as stated on you site, correct size for the wheel I have. 93392


So far the caps work as they should. The only comment I might add is that I had to modify the caps to make them fit. When I applied they, they just a shade too loose and felt like they would fall out when I put them in the water: they were on my boat trailer. So I cut the ends and spread them a little bit and they have fit since.

I bought this for my FWD Jeep Patriot Sport. A Jeep blog linked to this part so I ordered four. It fits PERFECTLY on the front wheels. But if you have a FWD it won't fit the back (too small). I recommend these for owners who want to remove the plastic center caps that come with the Sport version wheels. Side note: They arrive shinier than this picture portrays (a good thing). The metal finish was close to the chrome of the lug nuts. But I painted my rims black and plan to match this grease cap to them. 158959

I bought items three times from, two personal and one for work.I have been very happy with the products and the service I have received. Cannot find this 2.25" grease cap locally, this one fits perfect no issues and a great price. This cap is for a special built trailer for hauling a dory boat used for beach haul seine fishing. Spindles and hubs are from a late 1940s Ford or GM truck. I tell everybody with trailer issues about and I want to thank you George for your service. 206493

Difficult to find odd size grease cap SOLVED by The cap came quickly and efficiently. Fits perfectly after driven in--I wasn't sure if it would because: I was a little confused by O.D. and I.D. (outer and inner diameters). This could be explained better--some are measured one way or the other. I took a chance and got the right one . . . 206442

Worked like a champ. Exactly as advertised. I purchased a trailer with out dust caps. I replaced the bearings and races and didn't want moisture, dirt and grime getting back into the hubs. These worked great. Fit real snug and I won't fear them falling off in route. Thanks! 61813

I was very pleased with Karen who took my order and the company, the grease caps I ordered seemed to be of good quality and very reasonable in price and reasonable S&H cost also, they arrived at my door in just a few days. I would rate them 5 out of 5. good job guys. 155294

While there isn't much one can say about the quality of grease caps, the issue here was the size. I was unable to find one the right size in any local parts or implement stores. I was very happy to find one on etrailer at a very reasonable price. 101028

Do you have a question about this Grease Cap?

  • Replacement Grease Cap for Threaded 1.98 Inch Hub Bore that are 1-1/2 Inches Tall
  • We do have a replacement grease cap/dust cover set that will replace your existing thread caps with the 1.98 diameter AND they are 1-1/2 inches from the part just before the threads out to the top of the cap. Take a look at the Bearing Buddy Bearing Protectors - Model 1980T-SS - Threaded - Stainless Steel (Pair), # BB1980T-SS. For threaded covers in the 1.98 diameter, this is the only option we carry. Bearing Buddies will keep out water and ensure there is enough grease in the hub. A definite...

  • Choosing the Correct Dust Cap with a Drive-In Flange
  • At this time we do not carry a 2-1/8 inch diameter dust cap, however, we do have a few dust caps that are close to that measurement. I recommend using a precise measuring tool such as a dial caliper to measure the inner diameter of your hub bore. This will give us an exact measurement to go off of. Typically, when choosing a dust cap, you want to get an accurate measurement of the inner diameter of your hub bore and then choose a dust cap that is slightly larger. The next size dust...

  • Selecting Replacement Trailer Grease Caps Close to 2.1-Inches Outer Diameter
  • Trailer grease caps are offered in many sizes to fit a range of hub bore dimensions. Some of these sizes are very close to one another, such as 2.047-inches and 2.080 inches. It is best to measure to the nearest thousandth (three decimal points like the sizes above) to ensure a proper fit. This is easiest with a precision dial or digital caliper. All types of grease caps are shown on the linked page, including standard caps, E-Z Lube caps and Bearing Buddy bearing protectors. You can...

  • Bearing Buddy Recommendation for a 1.98 Inch Hub Bore
  • What you are looking to do is possible in theory, but we don't carry any hub/rotors that are for oil bath hubs like you are looking for so it wouldn't be a solution I could provide. The only solution I could provide for you would be to replace any lost Bearing Buddies with the # BB1980A-SS as these are confirmed to fit your 1.980 inch hub bore. You will want to make sure they are seated fully in your hubs as this is probably why your previous ones fell out. If you could find a hub/rotor...
