Trailer Grease Caps with Zerk Grease Fitting

Question

Question:

I thought I was buying a greasable cap to replace the solid steel caps on my trailer hub. I think I made a mistake. I dont see any grease zerk fitting to put grease into. Could I get some guidance? I dont see any instructions or diagrams of how this part is installed. That might clear things up for me. Thanks,

Grease Cap set # RG04-040 are regular grease caps that have a rubber plug on the end to access a grease zerk fitting on the spindle (end of the axle). They install the same as regular grease caps. It sounds like you are looking for bearing protectors such as # BB1980A which are for regular spindles. I have linked a video review for you.

Either the Bearing Buddy # BB1968 or the stainless steel counterpart # BB1968SS (for corrosion resistance) will work perfectly. These are designed to fit the 1.968" bore diameter on your hubs.

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

Answer 10

The 205/65-10 and the 20.5 x 8-10 would be very close in size. Assuming that 20.5 is the diameter of the tire and 8 is the width. The Kenda 205/65-10 Bias Trailer Tire with 10 inch White Wheel, #AM3H390, for example, is 8.3 inches wide with a…

The modern size equivalent of the 20.5x8-10 that you have currently would be the same size tire that is on the #AM3H340 that you referenced, 205/65-10. As long as the bolt pattern of your current hubs are 4 on 4 inch the wheels of this would bolt up…
