Re: Z71 front wheelbearing
Invest $15.00 +/- in a shop manual at the auto parts store. Study the wheel bearing inspection replacement procedure thoroughly prior to starting the job and keep the book handy during the job. It's going to be a messy job as you have to pack wheel bearings full of grease (unless Chevy came out with a sealed bearing assembly for the Z71, and I don't think they have). You can pack the new ones prior to beginning the rest of the job. Make sure you buy and install new races with the new bearings, and don't ding them up during installation. Be careful not to over-torque the spindle nuts when putting it back together (they don't have to be much tighter than finger tight, believe it or not). The torque specs are in the shop manual if you have a torque wrench handy. After you finish it, go back after a couple of hundred miles and retorque the spindle nut for good measure because sometimes those things tend to need a while to get seated well.
