Video Transcript for TruRyde E-Z Lube Grease Cap Plug Review

Speaker 1: Today, we're going to be taking a look at the TruRyde rubber lube plug that fits the 1.18-inch lubed dust cap. It's sold as a quantity of one. Part number is DC-RP. For the quantity of two, part number is RG04-010. These dust plugs are very inexpensive, but very critical component to any trailer hub system with the E-Z Lube axles. These, you can see we've got one missing here.

Our design to cap this off preventing water, dirt, and debris from getting inside the hub where it can cause major problems. In your hub you've got bearings that are going to ride on races. You can see the grease in there that keeps those working properly. Once dirt and debris gets in there, it starts wearing on those. The life of our bearings is going to be greatly reduced.

At the extreme side of that, it could cost us an entire axle. It's a very and simple thing to install.You can see the lip all the way around the outside here. That's going to go right inside the metal ring. Place them in. Push it in all the way around and that's going to be sealed up at that point.

We'll not have any issues with moisture or debris getting in there, causing us headaches. Now here's another great example of a dust cap that needs replaced. You can see it's kind of deteriorating here. We can start to see cracks in it. It doesn't fit properly all the way around.

That allows an area for the moisture to go right in. To remove it, it's quite simple. You just pop it out. Grab our new one and we'll put it in place. That'll complete our look at the TruRyde grease cap plug for the E-Z Lube grease caps.

Grease Cap Plug for E-Z Lube Grease Caps - Qty 2 - RG04-010

I tried this product for an aviation application. I own a DHC-2 Beaver aircraft that has a tail wheel axle that is 1.125 inch ID. I wanted an end cap that was removable because the axle tube is used to steer the aircraft with a hand held bar during some ground movement. So far the rubber cap seems to work. It has remained on during several flights. It is easy to remove and insert. The only problem may occur if the cap mounting area of the axle become oily or greasy which may allow the cap to slip off. It seems to need a friction fit to stay on. 138273

I cannot honestly give these a good rating as I cleaned up my old ones and will be putting them back into service. While the rubber on these is soft and pliable compared to the original equipment, the tolerances are all wrong to be able to get a snug seal. The groove in the seal that fits over the sheet metal cap is too wide in the first place, something like 1/16" with the metal being probably half that. Second thing is the hole is slightly larger then the center of the rubber when it is installed meaning this plug does not make a tight seal, my old stiff ones make a tighter seal and will be reused. Also, the part of the rubber plug in the inside has a much smaller lip the catch the metal then the old ones which probably makes it easier to get off and put back on but also means it can fall off much easier as the tolerances are such that it moves around and does not seal tight. In my experience I cannot recommend these. 475850

These are the caps that get removed to pump grease into an Ultra-lube hub. Perfect fit on my trailer with AL-KO 8490 axles and 10x2.25 brakes. Very nice price for a product that can be hard to find locally. I can't prove it, but my research suggests these cross reference to: + 85-10 + AL KO #568067 + Hayes #09213611 + TruRyde RG01-010 + Dexter 085-001-00 129297

The original OEM rubber caps on my trailer lasted less than 6 months and were cracked allowing water to seep in my trailer wheel hubs. These new grommets fit perfectly and are heavier rubber and seem like they are heavy duty. I recommend these to anyone. I also want to say etrailer.com upgraded my delivery at no extra charge and I received my order in three business days. My order included a very heavy tire and wheel. I call that a notch above great service. I will be shopping here from now on for all the products I need. 58022

Great live customer assistance not to mention your excellent website which not only shows the customer a set of photos with zoom to help the customer with a visual match of what he needs. Great detailed product description to make sure you are getting the right part the first time. The prices are great and shipping and delivery in much less time than expected. I look forward to shop at etrailer in the future. Thanks etrailer staff. 190625

Just before making an order for a wheel and tire I noticed that two axle grease cap covers had cracks in them. I searched the ALKO/Hayes part numbers and etrailer was the only site ( other than the mfg ) to list/cross ref the covers AND they were in stock for a low price. I made the order on Tuesday and they arrived Friday which is real good for free shipping from Missouri to N.E. Pa ! Parts arrived securely packaged and in perfect shape. I am very satisfied with this order. 266201

These caps did not fit as tight as the original Dexter's that I removed, so I was disappointed at first. I could press these in with my fingers, whereas the Dexter's I had to beat in with a piece of wood and rubber mallet. I've only put on a couple hundred miles on the trailer so far (6000lb tow behind RV), but it seems to be holding up and I don't see any concerning grease leakage. Based on this, I will replace the other three and see how they hold up as a set. 88282

I had purchased this same item previously and they fit great. Unfortunately, I had one crack after about a year of use. Given the inexpensive price, I decided to replace all 4 needed for my trailer. I bought 8 pairs (16 total) so that I would have plenty of spares for the future. I plan to change them out yearly just to be on the safe side. My shipment was delivered within a week. Good product, good price, good delivery ... what more could you ask for. 90954

After 5 years of storage, my original caps were in poor condition, but that was mostly due to the cotter pins behind being too long and cutting the caps from the back. Having no other option, I had to buy a set of the chrome dust caps just to get the rubber caps. So I was delighted to learn I could just order the rubber caps from etrailer! I have yet to install them, but in comparing them to my original caps, I don't see where I will have a problem. 395891

Product fit the hubs easily. It is a good idea to order a few of them. I took the trailer to the shop and after they had packed the axles, I noticed that one plug had popped off and the other had a lot of air pressure behind it by the time I got home. Bleed some pressure, from the plugs, if you are using your trailer brakes a lot and the drums get hot or you may be losing a bunch of them. 227075

The elements take their toll on these more than it probably ought to, but the cost of em is so inexpensive that it's not a big deal to change em. I change them every time I repack the bearings or at least once/year. Even though they are small and inexpensive, they play a very important role in keeping dust & moisture out of my trailer bearings. It's really cheap insurance to keep em fresh. 424040

I ordered the EZ-Lube grease caps by telephone because I wasn't sure the caps would fit my Bear trailer. I received excellent service by the phone rep who informed me that the caps would fit all such bearings. The cap was installed with minimum persuasion, and I am very satisfied with the product. I launch my boat in both fresh and salt water, and a good fitting grease cap is important. 213325

Great web site - easy to navigate - fast delivery - no hassle If you need trailer parts this is the site to use. The only thing I know that can make it easier is if you had some kind of log of products you bought last time so you didn't have to search for the item. Other that that this is a good site. I bought trailer grease caps before and needed them again. 262842

I really like these grease caps compared to the original caps that came on my boat trailer. The original caps fit loosely and were allowing some water intrusion to the bearings. These caps fit tight like caps should and they were the perfect size. I will order these every time a cap needs to be replaced and to keep a couple of spares on hand. 162992

The grease caps were as described and just what I needed- fit very well and seem much more durable than the original plugs on the trailer. My small trailer is outdoors all year at a storage facility and the sun is tough on degradable materials such as rubber. Order processing and shipping status was well tracked and communicated by etrailer. 554212

Was rebuilding my utility trailer and these plugs were rotten and needed replacing. Found these replacement parts on your site, and the description was perfect and the price was right.

I bought 4 four grease caps for my utility and boat trailers. They are a perfect fit and very easy to install. Having gotten several items from etrailer made this the right place to buy. All I could buy locally was a kit but I only needed the caps. The price was excellent and the items arrived promptly. I highly recommend etrailer. 343272

Great product and great price. Seems to be of better quality than the original (thicker material) but nonetheless it fits perfectly. Super easy to install and seats itself in the dust cap very securely; no worries about them popping off while traveling. Best of all no more grease being thrown all over the wheels and tires. 102691

Iwould reccommend etrailer for evryone's parts, as they know hwat part you require and are prompt in shipping.

The Grease Cap Plugs were a perfect fit, the only problem is they only last about a year but that's ok, as they are inexpensive enough that I buy a couple sets at a time to replace them. I can't find them in any local parts store and I use them on my boat trailer, atv trailer and covered cargo trailer. 303150

  • Zerk Fittings Keep Falling Out on Boat Trailer With EZ-Lube Spindles
  • Because the zerk fitting is a press fit, if they are falling out I would recommend simply leaving them out and replacing your existing grease caps with bearing protectors like Bearing Buddies. The Bearing Buddies you need will depend on your hub bore, or the outer bearing number. Once the fittings start falling out, there is not much that can be done to keep them in place. The holes where the zerk fitting was and the holes in the spindle that the grease passed through will not cause any...

  • Replacement Grease Caps for a Trailer Hub with 2-1/16 Inch Hub Bore
  • Instead of measuring the grease cap, measure the hub bore where the grease cap fits. You will need the most accurate measurement as possible so use dial calipers. You may find that you have a 2.047 inch bore so you could use bearing protectors like # BB2047SS. Or it could slightly larger, 2.080 like # BB2080. These are the 2 most likely sizes if you are coming up with 2-1/16 inches but measuring the hub bore with dial calipers would be the way to go.

Since your trailer uses EZ-Lube zerk fittings on the spindles you will be better off with a grease cap that has a removable plug.

  • Replacement Grease Cap Plug for a Tracker Boat Trailer

  • How Does an EZ-Lube Axle Work
  • On an EZ-Lube axle, the grease gets inserted at the end of the spindle through a zerk fitting and comes out of a hole that should be in between the bearings, filling them both. You would not be able to use Bearing Buddies because the zerk fitting at the end of an EZ Lube axle would interfere with the installation.

  • How to Measure a Trailer Hub for the Correct Size Grease Cap
  • You would need to measure the inside diameter of the hub opening to determine which cap size is needed. You would want to choose a cap whose outside diameter matches the inside diameter of the hub. Some of the most common sizes are 1.980 inch, 1.986 inch, 2.441 inch and 2.717 inch.

  • Replacement Hub Grease Cap for 2003 Jayco Qwest 10 B Camper Trailer
  • To determine the size grease cap you need, I'd need to know the reference number from the outer wheel bearing or the inside diameter of your hub bore. With that information, I can steer you in the right direction for the correct replacement grease cap for your EZ Lube axle. If you're just missing the rubber cap that goes into the grease cap, we offer # RG04-010 that fits a 1.18 diameter hole. Unfortunately, I don't have any cross reference information about your camper.

  • Rubber Lube Plugs Needed for Triton Boat Trailer
  • Part # DC-RP for a single plug and # RG04-010 for a pair may actually be what you need. Instead of measuring the outer diameter of the grease plug itself, you will want to measure the dust cap hole. If this measures 1.18 inches then this is the correct plug for you.

  • The part # RG04-010 is designed to fit a 1.18 inch grease cap center hole. If you measure yours and it matches that then these are the correct ones.
