First of all, remove the wheel and the cap and the nut and the shim, inspect the bearing. And stub axle. If it looks okay, and the grease too, put it back together, adjust the nut so the wheel just becomes harder to turn and back off by about one flat. New split pin recommended. It can have a little bit of play. If the grease looks really bad clean thoroughly and repack, there’s a trick to get the inner bearing out, [xj] Disassembling front wheel hub. How? - #2 by Doug_Dwyer
Bearings Timken, grease, I say anything but better grease will be a little better. ARB bushes are a good idea. Look at your steering rack bushes too while under there.
