With the wheel and brake caliper removed, use a screwdriver to gently pry the bearing grease cup away from the hub. Turning the wheel a little each time helps get the job done.
|
Remove the cotter pin, retaining ring, and spindle nut then remove hub or rotor-hub assembly.
|
Inspect the bearing and race for scoring, flat spots, or broken rollers. If all is well then repack with grease and skip to Step 10. If not, move to Step 4.
|
Use a drift and hammer to knock the outer race from the hub. Flip over the hub and use the same procedure to knock out the inner race, bearing, and seal.
|
Pack the new inner and outer wheel bearings by either pressing grease into each roller by hand or using a bearing packer and grease gun. The idea is to force the grease into all the surfaces of the bearing.
|
Selecting the right size drift is the key to the wheel-bearing tool. Use a drift that is slightly smaller than the race or seal to be seated into the hub.
|
Remove old grease from inside hub. Use the wheel-bearing tool to seat inner race into hub. Place the bearing in the race and use the tool again to seat the grease seal. Flip over the hub and repeat for the outer race.
|
Pack a good amount, but do not completely fill inside the hub with grease. Clean all excess grease from outside the hub.
|
Place the hub on the spindle. While spinning the hub, tighten the nut just enough to seat the whole assembly. Loosen the nut then re-tighten to specifications. As a general rule, use about half as much torque as it took to seat the assembly. Do not over-tighten!
|
Pack more grease into the bearing and bearing cup, replace retaining ring and secure with a new cotter pin. Gently replace the bearing grease cup being careful not to dent it as dents can cause interference. Remove all grease from the outer surface of the hub or rotor. Grab the top and bottom of the hub and check for play.
