you should just buy my hub conversion parts and eliminate them.... wink wink nudge nudge
If you can get a lifetime warranty part I would just do that, but in reality there are no such things as good unit bearings. I would double check with Currie though, as I know they make upgraded unit bearings for the JKs, might make one for the D60, but I doubt it. If you run oversized tires you will just wear them out again. If you plan on keeping the truck more than a few more years, just pony up for a conversion now, saves money in the long run.
