Video Transcript for Double-Eye Springs Wet Equalizer Bolt Installation

Hi there trailer owners. Today we're going to be taking a look at Redlines replacement shackle wet bolts. These bolts will make a great replacement for standard bolts or wet bolts if you are performing suspension work here on your equalizers and leaf springs and you find that they're all wore out. Over time your bushings can wear out, and once the bushings start to wear out, play will develop inside which will allow movement of the bolt inside of your suspension components. And that small movement will allow the bolt to travel up and down. And this little bit of movement is going to cause wear on both the bushing and the bolt and over time it will eventually destroy the bushing and it will also make our bolt a smaller diameter with an uneven wear pattern on the inside, so you'll need to replace it when you're putting a new bushing in or else you're still going to have that play from the bolt wear.What's nice about these bolts is that they do have a grease fitting on the end so you can grease your bushings.

Many of your factory suspension setups will have non greasable bolts with bronze bushings. And if you have that combination, those bushings are eventually going to wear out. They need lubrication. So upgrading to these will allow you to lubricate your bushings and your bolt to ensure that they don't seize together and also provide a lubrication coating between the two so we have no metal on metal contact, which greatly reduces the amount of wear.Wherever these bolts are installed, we have bushings in them and these are the design movement point for your suspension system. The bolt will pivot inside of the islet here on our leaf spring.

Same with our equalizer in the center and at the bottom here, all of these components move. And over time they will eventually wear out the bushings on the inside. But being able to lubricate them greatly decreases the amount of wear.What I also like about these bolts as they can be used with any type of bushing, too. If you're going to be using with a bronze bushing, they're great because they will fit in there and you also have a way to lubricate them, but you can also use them with plastic bushings. Many of your plastic bushings are self lubricating, so you don't want to lubricate them because the grease can potentially break down the plastic of those types of bushings

It is a 9/16 diameter bolt. Included with your bolt, you are also going to receive a lock nut, so when you're replacing the bushings on your worn out suspension system, I highly recommend replacing the bolts at the same time. It's going to make the installation easier. Often when you're taking apart your old suspension and you're planning on greasing 00:02:46 those bolts, the threads and things like that can easily get nicked and damaged because you do have to drive out your old hardware. And you can use the nut to help protect it when you're driving it out with a hammer.

But depending on how tightly they are seized inside your suspension system, you may still end up mushrooming the end and needing a replacement anyway. Replacing it with the lubricatable end here is going to further increase the life, so that way once you're done fixing your trailer, you can just keep maintaining it so you don't have to make those repairs down the road.They're fairly easy and straightforward to install. You can pick up as many as you need for however many bushings you're replacing in your suspension system. Let's go ahead and go over the installation together so you can the confidence to do it at home. We'll begin our installation by getting our tires out of the way. We're just working on the back axle for this one. So we don't need to remove our front. But depending on what all you're doing, you may need to remove yours as well. When removing your wheels, you want to make sure you got your trailer supported on the frame by jack stands. So you can use just a regular floor jack to lift it up.Once you've got all your tires out of the way for the area you're going to be working in, we can then start removing the bolts for wherever we have damaged bushings. We recently just had a new equalizer installed here and you can see we've got new bolts and shackles and an equalizer, but the bushings weren't replaced inside of the leaf spring here. So we're going to tackle that as well because we still got a little bit of a clunk noise because that bushing's wore out. To replace the bushings, you just needed to remove the hardware first. So for this particular set up here, the bolts are pressed into these shackles on the head of the bolt side. So we're going to remove both of these nuts and take the two out at the same time.We're going to take our bolts off. The bolt sizes can vary depending on your particular trailer. For ours, we're going to be using a 7/8, and you may or may not need to hold the backside of the bolt when removing these. They are supposed to be stuck inside of here, but over time they do rust and things wear out and they may not be. So it's not a bad idea to put a wrench on the other side to hold it.If we place our floor jack underneath the U bolt on our axle, we can relieve a little bit of pressure on it to make it easier to get the bolts to come out. Now what I'd like to do to get them out is I like to just thread the nuts back on there just a little bit and then tap them out with the hammer. Putting the nuts on it just helps prevent you from damaging your threads when you're tapping on them. And we can just slide it out there and you can see on our equalizer, we've got a brand new bushing in there, but on our trailer here, we've got an old one. And this old one here is so worn out that I can actually just push it out. Now if you we're unable to just slide out your worn out bushing like this, one of the best things to use to take them out as you can use an old bolt.So if we use another bolt that's slightly smaller and just place a flat washer on it, we've got a nice flat solid surface to drive it in. And we know since we're hitting all the way around, we're not going to ding up the outside of our bushing here with our hammer as we're driving it in. So we're just going to hold it in place and we're just going to tap it in with our hammer. A lot of times these tap in pretty easily. Every now and then you got to hit them pretty hard depending upon the rusty condition of your leaf springs.We can now take our new wet bolts and we can slide them into our shackles. Now if your old shackles are all worn out and the holes all wallowed 00:06:53 out, then I would recommend replacing them. We've got replacements here at etrailer, but if they're just a little bit of surface stress on them and the holes are fine, then you're okay. You can just slide your bolts right into them. Once you've got them slid in, we can come over to our bushing here and align them up. It is a bit of a snug fit. Sometimes you need to adjust the jack a little bit. WE're just going to line those up until they slide through.On the other side. Now we can take the other shackle and place it on there and then thread our nuts on. We can now tighten up our nuts. Now what you're going to want to do is hold the backside of your bolt with your wrench, because our bolt does have splines in it and it's going to spline into the inside shackle here, because the head of the bolt here has got those splines. And we don't want it to spin while we're tightening it down because it's going to rip the splines off and prevent it from working like it's supposed to. So we want to hold it steady, and then tighten it down and that will draw the bolts into the shackle and draw them tight together. And I do like to work back and forth with them just a little bit just to make sure that they are going to get pulled in.Once you've got them tightened down, it's always going of you to double check yourself and look here on the backside. You want to make sure the head of the bolt is flush all the way up against the shackle here. Sometimes the splines will prevent the bolt from going all the way in and it's not that it's preventing it from going in, just means you need to tighten it tighter until it draws it all the way flush.We can then go back and lubricate our bushings. Now we're only going to be greasing the bronze bushings, so that's going to be just this top one here on the leaf spring. Now that we've got our wheel back on, we can torque it to the manufacturer specifications and we're ready to hit the road.And that completes our installation of Redlines replacement shackle wet bolts.

As always the customer service is great and the products are as advertised. The website is full of great resource. My issue is with the shipping, more specifically the packing. Heavy items are just placed in a box with very little regard to cushioning or protection. This particular shipment had eight heavy shackle bolts and nuts in a box with hub seals. The seals weren’t in any sort of packaging and could easily have been damaged during transport. Only thing I don’t like about etrailer, terrible packaging.

I bought these to go with a set of new leaf springs for a skid-loader-trailer at a concrete company. I don't do their regular maintenance but I do notice fresh grease around the equalizers, so I take that as validation in my theory: "Give the boys a grease zerk and they'll grease it." Very happy with everything that I got from etrailer.com last year. Great pricing for known brands on a site that is so easy to navigate that I now use it as a reference for every trailer repair that I do. Who could ask for more?


Comments
Its music to my ears when I hear concrete guys complaining about grease globs on their perfect shop floor. The trailer is used almost daily and doesnt rattle, creak, squeak or lean. Very, very happy.

The parts arrived soon after I ordered them and all the parts appeared to be for good quality. I installed the parts on my old snowmobile trailer that I was rebuilding. I sometimes use the trailer to haul some heavier loads that were well beyond the rating of the old springs and that took a toll on them. These new 2000 lb spring are working well for these heavier loads. I used the Wet Equalizer Bolts with Locknuts and Grease Zerks to mount the leaf springs to the trailer with heaver duty shackles, they worked well.


Comments
They are working fine. I wanted to go a bit heavier that OEM and they work good for the heavier loads.

I love these things. I pull heavy loads day in and day out. 3-500 miles a day everyday. I was having to replace all the undercarriage bolts and shackles once a year due to wearing the bolts in half and making the shackle bolt holes oblong shaped. There was so much slop it worried me to be on the highway doing higher speeds. I did my one your inspection and there was very little wear. And that made me happy. Last time I had to stay up until 4am with one of my workers and cut everything out from under the trailer. Then re-weld and and install everything back. It's a serious problem when you don't have time to do it. This product will help save on downtime, labor and money.

I used these "wet" bolts on my leaf spring change out. I ended up using 3 per equalizer since that seems to be the location of most of the movement during axle travel and a friends 5th wheel had 3 installed on the factory set up, so that is what I went with. I painted a yellow mark on the head of the bolt in reference to the grease hole in the shaft, so that I could install them in the direction of "least resistance" when greasing them later, after reading how some guys have to relieve pressure on their trailer in order to get the bolts to take grease. I used Mystik 6 grease mixed with anti seize when putting everything together, then gave them 2 shots of Mystik 6 after installation. (I chose Mystik 6 because we always had good results with that grease when I was in the aircraft industry and it doesn't was out.) I did notice that the grease zerks did allow grease to return out of the fitting which means the spring behind the ball isn't doing its job. That is why I rated them as "good". There are different ways to install these due to the knurled shoulder. If you have access to an impact gun you can just tighten them in with that. Pulls the knurl right in to the shackle. Overall I like the idea of having a suspension that can be greased.

I bought a set of these bolts to replace the hardware in the triple axle suspension of my toyhauler. I had read about the benefits of a wet bolt kit, and after finding two broken shackle plates on my camper, decided I too needed to be able to properly lubricate the moving parts. These were a perfect fit and replacement for my original bolts. At the time I installed them I hadn't read about orienting the hole in the bolt to the 3 or 9 o'clock to ease pumping grease through them. I put them in at whatever orientation they were in my hand, but had no problem pushing 3 - 4 pumps of chassis grease through the zerk. I was able to observe grease flow out of the spring eyes around every bolt, and all of the zerk fittings stayed firmly in place when I wrestled the grease gun nozzle on and off. There were a few bad reviews about these press on fittings falling out, but I didn't see any evidence of that. I am very pleased with this purchase, and enjoy the peace of mind that comes with knowing I can properly service my suspension and hopefully extend the life of all the components in the system.

I had a trailer spring break this summer on the way home from a 2,700 mile trip. Our small luggage trailer just couldn’t take anymore rough roads. One of the springs broke through the centering bolt. The etrailer.com website and Tammie P. came through with replacement springs and accessories. Thank you Tammie P. And trailer.com!

by:

Attached a before and after picture. Everything fit perfectly. I used a right angle grinder with a cutting wheel to split the old nuts off. Heated the spring eye enough to melt the plastic to drive out the old bolts. Used an 11/16 drill bit to clean out the spring eye, then used a c-clamp to press the bronze bushing in then bolted and torqued everything like the instructions stated.

The replacement shackle link with wet bolts kit is by far superior to what was on the suspension system of the RV. There are no more snap crackle & popping sounds coming from the suspension system of the RV. Now that the components can be greased.

This is an upgrade from what was on the trailer before. You can grease the unit for longer life. I would recommend this.



- 126B2
by:

Grease fitting is not threaded, it is pressed in so it does come out. While it looks like a high quality bolt/but it’s very depressing to press it in the shackle the have the grease fitting pull out. Only 1/14 of the bolts but a threaded fitting would have had no troubles.



- 126B2
by:

This is a multiple product review. The long bracket are good. The shorter brackets are of the same good quality. The issue is using the short brackets with the shackles. The shorter brackets could be narrower so the shackle line up better with spring and other longer bracket. We used washers to make it align better. The greasing bolts are good, but could be longer. so we could only use 2 of the 6 and had to use normal grade 8 bolts.

3 of the 10 grease Zerk fittings have pulled out of the end of the bolt. They are pressed in...not threaded. They should be threaded!

Exactly what we ordered and was shipped quickly. Would purchase from Etrailer again.

These wet bolts are a great idea,also you must use with bronze bushings,they seem to be well made, I installed 14 along with bronze bushings on my toy hauler travel trailer,I had zero problems with the zerk fittings as some has stated,the problem I did have was with the amount of threads on the end of the bolt,the lock nut "supplied with bolts" was as tight as it would go but the head of the bolt on the other end was not tight up against the spring hanger or shackle so I had to go buy some lock washers and put behind the lock nuts,this allowed the bolt to become completely tight,so if the threads on these wet bolts were a 1/4 inch longer I would not of had this problem,after install greased them up and all is good,NO more squeaky suspension,by the way this is a 2020 brand new trailer.

This was a second purchase as we just purchased a newer and longer TT. The OEM bushings and bolts were worn enough to allow play in the suspension, allowing more sway. After the upgrade things are n I ce and tight, which will give me a better towing ecper.

  • What Torque Rating Should be Used to Install Trailer Suspension Shackle Bolts
    If you are using 9/16 inch shackle bolts which are the most common you will want 65 to 95 foot pounds of torque. If you are using 1/2 inch then go for 45 to 70 foot pounds. And for 5/8 inch bolts use 100 to 120 foot pounds. All of these components are designed to move so you don't want to over tighten anything.

    On the wet equalizer bolt # 126B2 it does not matter which way the hole faces. Up, down, left, right, anywhere in between, it's all good. A lock nut has mismatched threads a little ways along the thread spiral and either its threads, the bolts threads, or both will get gnarled up so given that these are suspension pieces it would be a good idea to just replace whatever needs to be replaced instead of trying to keep reusing the same lock nut. Really it is situational. The nut could...

    It really shouldn't matter what direction the wet bolts part # 126B2 install when used for equalizers or shackle straps.

  • Trailer Suspension Wet Bolt Not Taking New Grease
    Most likely there is some old grease inside the bolt that's clogging things up. You can raise the trailer up and remove the wet bolt in question to give it a thorough cleaning or just simply replace the bolt altogether. Unfortunately there's not a good way to clean it out while it's still in place.

  • How Often Should Wet Trailer Equalizer Bolt Get Greased
    Like you said it depends on how much use the trailer gets. If you do not use it very often then it is not working as much and the grease will not break down as quickly. So you will want to grease it at least once a year. If you do use the trailer frequently you might want to check it a few times a year or when you notice the ride quality has changed because the suspension is not moving as freely as it used to.

  • Do the Equa-Flex Cushioned Equalizers Need to Be Greased Regularly
    I spoke to my contact at Lippert Components Incorporated (LCI) about the Equa-Flex Cushioned Equalizers that you have on your trailer. They informed me that the equalizer does not need to be greased regularly though it would not hurt to spray a bit of white lithium grease like part # L11363 around the bolt sleeves. If you intend to grease them regularly I suggest installing wet bolts like part # 126B2 (see photo).

  • Is it Dangerous to Over Tighten Bolts on Equalizer and Shackle Bolts
    Equalizer bolts, like the Redline Wet Equalizer Bolt with locknut and grease zerk, # 126B2, should be torqued to yield. Equalizer bolts are not given a specific torque rating because they should allow some movement of the equalizer. If they are torqued down too tight, the equalizer will have difficulty moving and that could bind up your trailer's suspension. Simply tighten the bolts down until they are tight, but still allow the equalizer to move. I have provided an installation video...

Installation of the wet bolts and of the equalizer (in this case) are independent of each other.

  • Do Trailer Wet Equalizer Bolts have Press In or Screw In Zerk Fittings
    Without knowing what wet bolts you have it is hard to say for certain, but most likely the zerk fitting of the bolt is pressed in as that is the norm.

  • Wet Suspension Bolt vs a Regular Suspension Bolt
    The term, wet, in this case means that the head of the bolt has a grease Zerk in it and there is a channel that leads to center of the bolt. This makes it easy to grease the bolt while installed, as you can put a grease gun right up to the Zerk and shoot the grease into the center of bolt. Otherwise, with a dry bolt, you will need to find some other way to apply the grease. If given the choice, I would go with the Wet Shackle Bolt, part # 126B2.

  • What Is Bolt Length Measurement On The Redline Wet Equalizer Bolt, # 126B2 And Are Bushings Needed

  • Can Lock Nuts Be Reused on Trailer Suspension Bolts After Being Removed
    You may be able to reuse the same shackle bolts provided that they are the correct size, are not severely rusted, and are not cracked or otherwise damaged, but not the lock nuts. If you think your bolts might be rusted, cracked, or damaged I would definitely change them out for new ones. When used with lock nuts, the bolt threads could be compromised and I would recommend replacing them. The lock nuts cannot be reused. There are essentially 3 kinds of bolts and 3 kinds of nuts. First...
