Video Transcript for TruRyde Nylon Bushing Installation

Today we're going to be taking a look at the True Ride nylon replacement bushing for spring ends in the eye and also our equalizers. Part number is TRBU11566. These measure nine sixteenths of an inch in the inside diameter, eleven sixteenths of an inch outside diameter. They're designed to work with springs and equalizers that are an inch and three quarter wide. The basic purpose of these is to give us proper bolt fitment of out bolts when they go through our springs and mount to our trailer or mount to our equalizer. These are an exact round fit. They're going to give us really nice, snug fit on our bolt, and it's going to prevent the movement that we can sometimes get out of our trailer and also help to prevent some of the noise. The replacement process is pretty straightforward with these.

Sometimes if these are on an older trailer that's had some use and that's why you're replacing them, they're simply probably going to fall right out. They'll be really thin. We're going to use a seven sixteenths inch socket here and that usually works out really well for getting those guys to come out. Once our old one's out, it's just going to be a matter of putting our new one in place. You can see that slid right in.

Sometimes you will have to again use your socket to drive it in, maybe put a block of wood there and tap down on it. Whatever you prefer. It's just a really quick, easy way to switch these out, keep that proper fitment for your trailer, and keep a lot of that movement and play to a minimum. When it comes to our equalizer here, typically one side of the hole is going to be more rounded and a little cleaner looking than the other side. You can see how there's almost a lip over the edge of our bushing. We want to drive it out from this side out that way so it'll come out pretty freely and we won't have to fight it too much.

Again, if you have to knock it out, a socket is all you're really going to need. Those pop right out. Grab our new one, it'll go in that same direction. That's all there is to it. New bushing in place, ready to put it back on the trailer once we replace the other two here. The same bushing is going to work for all three locations of the equalizer and on both ends of your spring.

On a typical, single-axle trailer we're going to need four because we don't have an equalizer. Once we move into a tandem trailer, we're going to move up to fourteen, and a triple axle trailer we're going to require twenty-four. That's going to complete our look at the True Ride nylon bushings for the one and three quarter inch wide springs and equalizers, part number TRBU11566.

Spot on bushing for my leaf springs. Only suggestion would be to include instructions for lubrication. I wasn't sure, so I coated them inside and out with a thin layer of hi-temp grease. 337849


Comments
Michael, thanks for your review and your business. You will probably find it easier to the shackle bolts into the bushings if you lightly grease the bolts. A small amount of lubrication will both aid installation and provide a degree of lubrication for the whole assembly. You can use a general-purpose lithium grease like L11316.

The parts I bought from you to repair the suspension on our live stock trailer did the trick of getting it roadworthy. We dont use it often, but the couple times weve had it on the road since the repairs have been uneventful and thats a good thing when you have a couple tons of beef on it.

I Waited Too Long to Replace Trailer Bushings -The past few years I would hear “clunking” sound (different than “squeaking”) from my boat trailer, but I got concerned this year as it seemed louder. -With the boat off the trailer I could see wear around the shackle bolts -I called eTrailer to order the parts and was helped by Kayla to order the bushings/shackles/bolts/nuts for my tandem axle trailer -After trying to press the bushings in I realized I measured poorly and had two different bushings, the equalizer had 1 size and springs had a different size. -Amanda helped me get the second set of bushings (delaying the project for 5 days…but my fault) Right or wrong: -I applied anti-seize compound to the shackle bolt threads -I pre-loaded the “wet” bolts with marine grease to fill them up before inserting them into the suspension, adding grease when everything is installed -I tightened the bolts very securely and they backed off the nut ½ turn to allow for suspension movement Lessons learned: -Look for different size bushings in equalizer/springs and measure correctly ID & OD precisely -It takes some time to do this job (about 4 working hours per side) so try to do it when you are not under pressure -If you want the re-paint some parts, allow for primer and top coat drying time, i.e. overnight which adds time to the project, but it comes out better -Have a big breaker bar & extension/enforcer to help get the nuts on & off. My ½” impact gun could not tighten them all the way -A large “C” clamp will press the bushing in smooth & straight instead of using a hammer & block of wood “caveman style” -Annually inspect your trailer suspension for signs of wear and listen for increased noise Thanks again to Kayla, Amanda and eTrailer for help with this project. 520272

Ask the Experts about this TruRyde Trailer Leaf Spring Suspension

  • Recommended Bushings and Bolts for Trailer Suspension Upgrade
    The Bronze Bushings # K71-291-00 will work well with the wet bolts # 34007-187-00 which are 3-5/8 inches long. The usable length is 2-1/4 inches which will work well with the bronze bushings that are 1.74 inches long. As you stated, wet bolts can vary in length and should not be used with the nylon bushings # TRBU11566 as they cause them to break down prematurely. If you are simply wanting a bushing kit that requires no maintenance and will last, I recommend the Never Fail Tandem...

  • Upgrading Trailer Bushings Greasable Bolts and Equalizer Suspension Parts on a Alpenlite 5th Wheel
    Installing brass bushings of the proper inner and outer diameter and length is possible. In my experience brass bushings do not last any longer than nylon bushings and they are much harder to find in the correct size. At this time we do not carry brass or bronze bushings properly sized for double eye leaf springs. Upgrading to wet shackle bolts would be a good idea and would increase the life of the suspension components, no matter the construction. You will need to match the length...

  • Dimensions of Hangers and Equalizers on Tandem Axle Suspension on 16-Ft Trailer
    Front and rear springs hangers should be equally spaced around the center hanger and spring equalizer. It may be that your trailer was modified (if not originally built) with a different height center hanger and that might be how the spacing became how it is. Also, it may be that at some point the shackle straps were changed to a different length - we offer three different lengths: 2-1/4-inch, 2-5/8-inch and 3-1/8-inch. On a tandem axle trailer the 2-5/8-inch length is most common. It...

  • Recommended Tandem Axle Suspension Kit for Converting to Double Eye Leaf Springs
    The appropriate vertical height of double-eye leaf spring equalizers and hangers mostly depends on the axle diameter. 2K axles typically have a diameter of 1-3/4-inches. If you were to use a tandem axle kit such as # APT5 which has hangers that are 3-3/4-inches tall and equalizers that match well you'll be all set. It looks like you have just enough room to install this kit, as shown in the linked diagram. You will have about 5-inches of clearance between the trailer frame and the axle...

  • Should Wet Bolts be used on 3,500 pound Dual Axle Leaf Spring Replacement on a 2000 Skyline 26 Nomad
    As long as the wet bolt that you are intending to use is the appropriate size, wet bolts can be used on the fixed side of leaf springs. You will want to make sure that the bolt is the correct diameter, length, and that there is not a clearance issue with any other parts of the suspension when considering using a wet bolt. I have included a helpful article that explains a some differences in types of suspension bolts for your reference.

  • How to Use the Leaf Spring part # PR4B with 1/2 inch Bolts

  • Grease Recommendation for Suspension Components
    A Moly EP grease like part # L10314 would work well for greasing the suspension components of your trailer. For a grease gun to use the wet bolts and get grease into the # trbu11566 with the wet bolts you would want the # L30200. As long as the wet bolt that you are intending to use is the appropriate size, wet bolts can be used on the fixed side of leaf springs.

  • Should There Be Play Between the Bushing and Wet Bolt of Trailer Suspension
    If there is a tiny bit of play in suspension components that are designed to move you would be fine. 1/16 of an inch isn't very much. Typically there aren't any torque ratings for shackle bolts. We run them down tight or until the knurls are no longer exposed under the head of the bolt, then back them off enough to prevent the suspension from binding.

  • How to Determine if a Trailer Axle is Out of Alignment or Suspension is Worn
    It is unlikely that worn bushing would cause poor tracking or sway unless something else was also worn. Look for any egg-shaped holes in the hangers, spring, equalizers and any other suspension component. This would be an indication of excessive wear and replacing the worn parts would likely help. If you were to measure from a single point on the trailer coupler to the center of the the axle on one side, then do the same thing on the other side, the measurements should be nearly identical....

  • Wet Equalizer Bolt With Grease Fitting # 126B2 Recommendation to Prevent Premature Suspension Wear
    It is recommended that you lubricate the shackle bolts regularly. I would recommend you get a Wet Equalizer Bolt like part # 126B2. This bolt has a grease zerk fitting that would allow you to keep fresh grease on the bolt preventing dirt from accumulating causing premature wear. I attached an FAQ article on trailer suspension that you might find informative.

  • Should Trailer Hangers be Spaced Equally Apart on Tandem Axle Trailer
    Ideally you want the hanger spacing to be the same on a dual axle trailer like what you are building but a slight difference may not cause any issues. The shorter spacing that you have between the equalizer and one of the outside hangers essentially results in a leaf spring stack that is just a tad too long. The only thing you will want to watch out for is the chance that the shackle straps on the equalizer can make contact with the trailer frame. What you can do is manipulate the suspension...

  • Are Bushings Included in Double-Eye Springs
    Bushings are sometimes included in double-eye leaf springs. Sometimes they wear out and need to be replaced. You can purchase replacement bushings separately. You will need to know the bushing's inner diameter, outer diameter and the length of the bushings to order replacements. It does not matter which material, nylon or bronze, the bushings are. Also nylon and bronze bushings have about the same longevity.

  • How To Determine Trailer Leaf Spring Replacement Based on Axle Capacity and Other Components Used
    For your replacement leaf spring, there are a few things to consider. The number of springs in the stack doesn't determine the capacity, so you will need to know the capacity of your axle so you don't have springs that are too stiff or not strong enough for your application. For instance, if your springs are for a 3,500 lb axle, then the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275 may be the correct replacement even though it is 4 leaf versus 6 because the...

  • How to Determine Correct U-Bolt Kit and Leaf Spring Bushing for a 6,000 Lb Trailer Axle
    A 6,000 lb axle is usually going to be 3" in diameter. Therefore, for the u-bolts you can use part # APUBR-8 for 7" long or part # APUBR-9 for 7-1/4" long. You can measure your existing u-bolts or from the bottom of the axle to the top of the leaf spring pack in order to determine which length you need. You can always choose the longer option and cut away any remaining threads if necessary. Most leaf springs for 6,000 lb axles are 1-3/4" wide and will use a 9/16" bolt. If this is the...

    If you use a higher rated leaf springs on a lower rated trailer they will work but will cause stiffness in your ride quality.
