  • Q:

    1990 GMC Suburban R1500 5-Lug 2wd 10 bolt rear diff. 8.5" ring . . Does this kit (search result for "pinion shim kit" for my vehicle) contain both the main pinion shim(s) (for the larger bearing) AND the pre-load shim(s) (for the smaller bearing) ? . . The 2 different shims will have a different inside diameter, and I'm only seeing what appears to be one size in the stock photo . . If it contains just the shims for the larger bearing, is there another kit for the pre-load shims, or a combined kit containing both sizes?

      I'm glad to be of assistance, Chuck! Yes, the shim kit is for the pinion shims for your GMC. I looked into the catalogs of Motive gear and was able to locate the carrier shims for your truck. The shims with the smaller bearing is Motive Gear Differential Mini Install Kit

  • Q:

    My c lock popped off and when I got towed home,I look inside the rear end and found my c lock off plus what looks like a differential shim wore down to almost nothing.
    My question is what size o-ring do I need to keep the c lock in place and where does these shims go?

      A:

      This shim will work on your 8.8" ford rear end traction set-up. Take your clutch pack including the shim and measure it with a C-clamp and then caliper. The normal track set up for the traction line should be like 0.640" to 0.645". Place(Head) the gear in a table(or any surface) and the traction set up in the gear is as follows - place the steel shim(Motive Gear Differential Shims), then a fibre plate(with round tab on corners), then 2 steel shims, then a fibre plate, then one steel shim, one fibre plate and finally one steel shim. So you would be using 5 Steel shims and 3 fibre plates as mentioned in the above setup. This should be an ideal traction - lok clutch pack set up.
