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.

<font face="Comic Sans MS">They are sealed bearings. I dislike it but that's how they do it on these new fangled trucks (from about 1989 up)... Try searching the GM IFS forum for "Hub bearings" and the like, and you should find a plethora of information...</font>

Re: Z71 front wheelbearing

this is a very easy task i have done a few. three bolts on the back of the spindle. a nut on the cv shaft and i bit of prying to get it off. easily done in the driveway. any questions just ask in the gm ifs board. good luck.

That makes for a super-easy swap then. I have mixed feelings about sealed bearings, but there's no debating the fact that it's much quicker and easier to change them out than it is to mess with packing tapered bearings, driving races in and out, and torquing (and retorquing) spindle nuts.
