If your existing grease cap is marked 1.97, you're probably needing Bearing Buddies for a 1.98 inch hub bore. The stainless steel model, part # BB1980A-SS would be ideal. Bearing Buddies and grease caps are meant to fit tightly, so be sure to verify the diameter of your hub bore. A digital caliper is best for this, as a ruler or tape measure usually isn't accurate enough.

Bearing Buddies are only compatible with standard spindles, not EZ-Lube Spindles with the grease zerk.

You can measure either the outer diameter of the part of the dust cap that fits into the hub OR the inner diameter of the hub where the dust cap goes using calipers such as #PTW80157. Calipers are needed because the measurement has to be as accurate…

The closest bearing buddy we have would be the 1.980 part #BB1980A that it sounds like already tried. The next smallest size we have is the 1.968 part #BB1968 which unless you measured wrong would be too small. I am surprised you couldn't get the…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
