The Bearing Buddy Bearing Protectors # BB2047SS fit hubs with a diameter of 2.047"(52mm). These are stainless steel construction to prevent corrosion and will allow you to fully fill the hubs with grease without dismantling the hub assembly.

A Grease Gun # L30416 or similar is needed with your grease to fill the hubs. I recommend the LubriMatic LMX Industrial Strength Grease # L11390 if you are cleaning out the hubs. This grease works well in hot or cold temperatures and bonds to the metal to reduce friction and wear.

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…

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…

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…
