Hey all. In the next few months I should be finally getting the 8.8 chopped and put into the car. I have a full rebuild kit and a trac-loc rebuild kit. I am looking for some tips...

I heard there is a trick about re-using one of your old steels in the the rebuild?? adding it in extra or something to tighten the posi action? Can anyone that know this let me know where I am supposed to put the steel in??

Any other tips or ideas that are recommended.?? I will be using FMS gears for the gear change and I heard that is the best route for simplicity of set-up...
 
It is 2 fibers that you will be reusing from the old pack. Find the best 2. With the side gear laying on bench add plates in this order. fiber/steel/f/s/f/s/f/. So you will have a total of 4 fibers and 3 steels on each side gear and will be discarding 2 new steels. You should get a shim kit with your kit also. Now take the .035 shims and put 1 one on top of each side gear on top of the last fiber. Now try to assemble this into the carrier. If the spiders wont twist in. replace the .035 with .030 or .025. If it twists in easy then step up a shim size. The trick is to use the thickest shim possible. Both shims must be the same on the left and right side gears. This setup gives you 33% more surface area = 33% more lockup. :D
 
I don;t think I got shims in the kit, they could be there, but I only remember seeing frictions and steels... was a generic kit, not a ford item.

I will find out tonight when I get home.

THANKS FOR THE INFO!!! heh mischief...
 
OK sounds good,

FYI - My kit has 8 steels and 8 frictions... I wonder if I could have the guys at work take my old steels and machine shims out of them also?? if my old shims are bad or not enough?? .030 pretty thin, but they might be able to do it..
