Front Bearing Replacement Procedure
1) Jack and support truck
2) Take off the wheels
3) The fronts have 4 bolts on each caliper. Take off the two 13mm bolts, that will get the caliper off.
4) Then take off the caliper mounting bracket, that’s 18mm, 2 bolts, caliper bracket will come off
5) Remove the dust cover from the wheel bearing with a hammer and a flathead screwdriver, be careful not to hammer too hard, just get in-between the hub and the cover, and pry it off.
6) Bend the cotter pin with needle nose pliers and pull off.
7) Remove the cotter pin retaining cover off
8) Remove the 27mm nut from the middle.
9) Remove the outer wheel bearing by just starting to remove the rotor, the bearing and the retaining plate.
10) Put the 27mm back on and pull the rotor down and out at the same time. The rear bearing should hang up on the nut and come out of the rotor taking the dust seal along with it
11) Time to pack the bearings, take new bearings and put a wad of grease in your hand, and work it into the bearing little by little putting the sides into grease and hit it on your hand, forcing the grease up to the top; you should do this till you see new grease on both inner and outer. Or if you have a bearing packing tool then that will make quick work of them.
12) Take the new inner bearing; put it in the back of the new rotor
followed by the inner dust seal. Carefully hammer into place, don’t bend the seal
13) Put the rotor into place on the truck on the spindle.
14) Install outer bearing followed by retaining plate
15) Install the 27mm Nut, hand tight. Follow the torque sequence:
a) spin rotor clockwise and tighten nut to 30 ftlbs
b) back it off two turns
c) spin rotor counter clockwise and tighten to 24ft lbs
d) back it off 1/3 of a turn
e) spin rotor clockwise and tighten to 17inlbs
16) Install the cotter pin retainer followed by the cotter pin, and bend it back with needle nose.
17) Install dust shield with a hammer, make sure it’s centered and seats all the way
18) Put on caliper bracket 18mm bolts, TIGHT, turn the wheel so you have room.
19) Install the pads on the rotor in the caliper bracket. Now is a good time to put a coating of Brake Quiet on the back side of the pads and let it set up before installing.
20) Spray rotors down with BRake Clean liberally
21) Install the caliper; it should slide over the pads and right into the caliper bracket.
22) Take the 13mm and put the two caliper 2 bolts in.
23) Reinstall wheels and torque to spec (120ft lbs)
24) Pump the brakes before driving to make sure you have pedal pressure.
And you should be good to go.
