So I just finished my front end rebuild and the preload is pissing me off.
Did the whole fishscale thing and had it at about 9-ish lbs, Drove the truck around a bit and checked the wheel bearings this morning, they were loose... So I went home, jacked the front end up, and left the tires on.
I then carefully adjusted the first bearing nut just to the point to where there was no play and then tightened down the locking nut. I know the locking nut adds a bit more preload so I called it good at that. Drove the truck down the freeway to work (15min drive) and the hub was pretty darn hot to the touch. Not hot to were you couldnt touch it, but close...
I went home and took the drive flange off and the grease looks and smells fine (not burnt obviously) and the outer bearing looks perfect. So basically I put just enough preload to take away the slop and the bearings get hot... back it off a bit, and the damn wheel is loose.
Is it normal for the hub to get that hot? or should it just be warm to the touch?
I also recently added 315's which increases the rolling mass of the wheel making the brakes work harder. Could a large portion of the heat im noticing be from the rotor transfering to the hub?
I hate setting preload on bearings... there's no "sure fire" method, its just a bunch of guessing bull****.
