  Q: How to check and replace front wheel bearings on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

  A: In most cases, the front wheel bearings should be checked whenever the front of the vehicle is raised, typically coinciding with brake pad replacement. The vehicle must be supported safely on jackstands and each wheel assessed by spinning it while checking for noise, rolling resistance and freeplay. You should grab the top and bottom of each tire to check for excessive play as you move the wheel in and out on the spindle; if there is any noticeable movement, bearing inspection, repacking with grease or replacement is required. After removing the wheel, remove the brake caliper and hang it out of your way possibly using a wood block between the brake pads for separation. Thereafter pry out dust cap, straighten and remove cotter pin then take off nut lock, nut, and washer from spindle. Slightly pull hub/disc assembly outwardly then push it back to facilitate removal of outer bearing. Then separate hub/disc assembly from spindle using screwdriver skimming seal out of rear side of hub keeping in mind how it was oriented during its installation. Proceed further to remove inner wheel bearing, clean all components thoroughly with solvent before carefully inspecting them for damage on races or bearings themselves. Replace any defective bearing races at a machine shop if necessary making sure that old bearings are not installed on new races. Thereafter pack bearings with high-temperature front wheel bearing grease and apply thin coat to designated spindle areas. Finger dam grease inboard of each bearing race inside the hub to contain excess grease. After this insert grease-packed inner bearing, a new seal then put outer bearing on top. Place washer on spindle followed by spindle nut which should be tightened gently; spin hub while tightening to approximately 20 ft-lbs then loosen 1/4-turn and finally secure snugly by hand using new cotter pin plus nut lock. Next install dust cap; replace brake caliper; re-attach the wheel then check condition of bearings by grabbing top & bottom of the tire. Finally, lower the vehicle.

  Q: How to replace the rear Wheel Bearing on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

  A: To remove the axleshaft and oil seal, you will first need a bearing puller. Attach the puller to the slide hammer, the bearing can be extracted from the axle housing. After removing the bearing, the recess should be cleaned out. The new bearing can then be installed using a bearing installer or a piece of pipe against the outer bearing race. Ensure that the bearing is tapped in fully and that the numbers are visible from the outer end of the axle housing, and then install a new oil seal before reattaching the axleshaft.
