Too blurry

Did you measure the thickness of your clutch packs (including shims). If your clutch pack is too thick, you'll never get the spider gears in. Here's a video explaining exactly how to measure them, and what the specs should be. I set mine up a little tight, and it was hard to get the spider gears in, but the unit works great this way. If the diff is out of the rear, you can also use 2 bolts, with 4 large washers and 2 nuts, to compress the side gears against the housing while you work the spider gears in. First you need to check the thickness of your clutch packs.

your problem is you are using too thick a shim, the kit usually comes with a .030, .035 and a .040 shim for both the side gears....find out which one you are using with a vernier caliper....usually the new ones are labeled....anyway use the next size down and reassemble until you can roll them in

i did use the bolt method to hold the side gear in and i believe my kit came with only one shim and states it is presized to fit the factory 8.8 rear end it has a .30 shim the kit is http://store.summitracing.com/partde...5&autoview=sku

make sure you have everything in order and the proper amount of friction plates and metal plates installed and not one to many, I've never had an issue using a .030 shim, infact I gave mine a tad extra for added preload...035 to be exact to take up some excessive backlash on the worn spider gears I had

does anyone know what should be the over all thickness of the clutch pack including the shim?? the kit came as it stated preordered i think its fssfsfsfs shim........ if i rememeber correctly its at i thik .661 for thickness

im thinking i need to take out some shim???? Would you all agree? if i do the my measurement subtracted from 640 i get a negative number........

if it will not roll in then yes for sure you need to subtract shim

finished it this evening ...... no change in shimming..... believe it or not all i did was remove the clutch packs and whip off the excess oil and tried it all again and it went right into place....
