Front Wheel Bearing Change


Jack up, remove wheel and caliper.


Remove dust cap (a tool exists for this)


Remove cotter pin


Remove locking nut, nut, washer and outer bearing


Parts removed so far: dust cap, cotter pin, locking nut, nut, bearing, washer
Note: there is no seal on the outer bearing as the dust cap serves the same function

Pull wheel hub assembly. Here is a pic of the back side. You can see the inner bearing and its seal


Pic of the spindle with hub removed.
Note: old grease typically has lead in it. dispose properly ( 78 2plus2 )


If you are replacing the rotor then you need to do this to separate the hub from the rotor.


Pry out the inner bearing seal


Pull out the inner bearing
Carefully drive out races
Note: Be careful not the gall the hub when driving out the old races. That can make getting the new ones in a real pain. If the hubs are already galled, a small sanding drum on a rotary tool can be used to smooth the surface. (HizAndHerz)

I like to throw the races in the freezer a couple of hours beforehand and warm up the hub a little bit to make the races go in easier. (HizAndHerz)


Here is the old race. It is easy to see the wear


Home made front wheel outer race driver. 1" pipe coupler with slight grinding to fit  (thread is inside)


Here is home made front wheel inner bearing driver  2" threaded pipe coupler. Note the lightly ground threads to make it fit.


Apply anti-seize to the hub where the race will be placed

Install washer

 


Install nut and torque (20ft-lbs). Rotate a few times then re-torque


Test pre-load with fish scale and wheel stud, Adjust nut if needed ~1lb or 2kg


Install nut lock


If the nut lock's V slots do not line up with cotter pin hole, simply pull nut lock off the nut, rotate the nut lock then reinstall. The V's are offset so
that they will line up


Install NEW cotter pin


Installed


Bend cotter pin
Note:
Cotter pin not installed correctly. The pin goes with the round bulge facing out. Before using a new pin, hold one end in a vise and twist it's other end 90 degr. Now you have the famous Rolls Royce twist that allows a correct install. so that the two legs of the pin can be folded back against the outside of the retainer back to front w/o hitting the grease cap or having to cut off one leg of the pin.
