Expert Answers about Grease Caps

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 cap with

How to Determine the Correct Bearing Buddy for a 2013 Carry-On Trailer
There are a few ways to determine which Bearing Buddies will fit your 2013 carry on trailer. The easiest way may be to find the manufacturer and model number of the hubs on your trailer.

At 3,000 pounds your hubs are probably smaller and you would need a smaller grease cap.
