Ok, gonna repack or replace my wheel bearings next weekend. Aint never done it before, have paid to have it done, but I aint never done it. Anyway, the bearings that are in it are probably the originals, should I go ahead and replace them? What would the approximate cost for them be, and what other parts would? I know there are seals etc in there, which ones do I need to replace when I do this? Also while I have it apart, may as well go ahead and have the rotors turned for an approaching brake job. While I am that far in what else should I go ahead and do? The U-joints are probably the originals, how much more work to go on in and replace them or should I just wait till they break? Also, what should I look for to tell me to replace them instead of just repacking? The races I assume show wear like a main bearing from a motor, so I think I can figure that one out. Ive never even had the locking hubs off of the truck, so I dont really know what Im getting into lol, any tips or pointers are appreciated, but I have some mechanical knowledge lol. Now on to the realm of tools. At pep-girls They have the hub sockets w/ the little prongs. I assume this is the tool I need for the hub nut(probably not the right term haha) and they have two that could possibly work. One is a half ton from 73-90 fullsize chevy's etc. Since I have the 8lug 10 bolt this will probably be the correct one. The other is a 3/4-1 ton from 73-90. Its visibly larger, but 1 tons have D60's and 3/4's D44's or 10 bolt's. Which is it? The larger or the smaller? Any recommendations are appreciated. Thanks. Chris.
