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.

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


Same as described above.

I couldn't find the hub seals at the neighborhood parts store, they wanted me to do a complete replacement which would have cost much more than what it cost at I am very satisfied with the product, the cost and the quick shipping. 204151


The fit was perfect so I have no complaints. No grease leaks even in the hot weather. They are on my Pace American enclosed trailer.

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 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

Installed the grease caps on my trailer today for a perfect fit !!. 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


Product still fits well and is pliant. Very satisfied with this product and etrailer.

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

by: JDM06/19/2017

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

Worked great, could not find them locally and found them here. Always afraid to order from a site I did not know but received order confirmation very quickly along with a name and number to call with questions! Very nice, wish some of my more complicated purchases offered service like that. Anyway, they arrived very quickly and they worked. Not much you can say about a rubber plug. 14406

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

Product was exactly what I ordered, the only problem was I ordered I think on a Mon. and did not receive it until the following Fri. 9 days later was supposed to come UPS they past it on to the post office, as slow as the post office is it would have been better to send it by the post office in the first place, Kansas City, Mo. to Minneapolis, Mn. 431370

Product was what I needed. Only needed one, but ordered extra just in case. I am glad I did, disappointed with shipping, wouldn't order again if I needed in reasonable time, would have been better if they would have just shipped first class post office would have got sooner, would have been cheaper for company too. Did Ups surepost took like week. 355767

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

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

by: KungFuDonkey10/05/2013

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.

Have original EZ lube caps. The rubber on the caps have rotted and now grease is getting all over my tires. Ordered these and they went right in place of the originals. These seem to be a little thicker than my originals (good thing) but they dont have "EZ Lube" engraved on them (bad thing). 22532

Bought these to replace the originals purchased years ago. My trailer sits outside so the get weathered. Popped these new ones in and though I thought they could have dirt a bit more snugly, they were easy to insert and time will tell if the looser fit will allow grease leaks or not. 442715

I purchased these grease caps for 7000 lb axles on my horse trailer. They were a perfect fit and good quality. This is not my first purchase from Etrailer and it will not be my last. They have the products that I need at a resaonable price. And there shipping, can't be beat. 238454
