Had to switch and change things to pass smog here in Vegas, but as I was down there I was looking and around the cap it says to not remove it. Is that just them covering their butts or really don’t remove? Also, thanks for the recommendation on the axle nuts, was just going to go with Dorman ones I had already gotten from autozone. Thanks for the reply’s guys, y’all are great.
It says do not adjust, which is due to the bearing design being fully self contained, which was still a pretty new concept in the early 90s. Old cars you have to adjust preload on the bearing/spindle, which can be adjusted later from wear, ours the bearing is torqued to 250ft/lbs and that’s that. The dust cap is just a dust cap, itself sort of an artifact from those older designs as there’s really no path for debris to get into the bearing(though it does keep the nut and spindle from moisture and rusting)

Since the bearing is a tapered roller, rotate the wheel while doing the initial tightening, it will loosen up as you rotate it, as the two halves of the inner race go together. Make sure there is grease inside; you can very slightly separate the two inner races to see. I'm running about 25% on greased ones, lol.
They’re actually ball bearings, not tapered rollers

That's one of the knockoffs; is there a partnumber etched in the side of the race?
Its factory original, that wasn’t the only one I pulled apart, the ones on my car are timken and it’s the same thing.

You can’t get them out with a press, you need to slip it part way onto the spindle and pull on it diagonally to create resistance to release the inner race, from there you can access the ball bearings. The pics are unfortunately gone but this thread describes it in detail Figured out how to lube the SN95 hubs...

Regarding failure rate it’s shockingly not uncommon to find brand new name brand hubs with little to no grease inside them as well, that concern is what prompted me to disassemble/pack mine but they were ok to begin with.

I’m not saying you’re wrong about tapered rollers being better for the application but the ball bearing hubs hold up pretty wel on modern cars that have far more cornering capabilities than the oldies with tapered rollers, and they never need adjustment until they’re truly kaput. Let’s face it, the hubs are the least troublesome component between the wheel and pickup points in our front ends.
