I have an 02 cladded av.... Love the truck but somehow managed to strip out the spider gears in the rear end. I just ordered the replacement gears from gmpartsdirect. I do have a limited slip Diff. REAR of course. I have been searching all over the net for a "How to" on changing the spider gears on this type of Diff. I can't find anything on this... Does anyone have any literature or info on this? I'd like to do this myself if at all possible. Not sure if I need any special tools for this job. If it wasn't a Posi I know it'd be easy but I have never done a Posi. ANY HELP?!?!?! THanks mxz71@hotmail.com
