pinion depth, bearing preload and such
So i decided to reuse the same gear ratio on my 8.8 rear end, now my question is mainly about the pinion itself and all the shimming involved. Being as I'm using the exact same ring and pinion and nothing has changed could i just measure the previous shims with a caliper and put in the new ones that came with my rebuild kit. The reason i ask is because it looks like setting pinion depth is fairly tricky and very expensive with the tools. i suppose worse case scenario i have a machinist help me out, but id rather not so help would be appreciated.
Thanks much guys

I'm doing an explorer 8.8 swap. I bought a complete rebuild kit from ford racing so i did take the pinion out to replace the bearings, races and shims. However if i replace the shims with newer ones of the same thickness i cant see why that would pose a problem but thats why im asking, and ya its a LS i just rebuilt.

When I rebuilt my 04 Levell II I reused all shims. Double checked/set bearing preload (used two crush sleeves til I got it right, then new pinion nut for final assembly), checked pattern, all were within spec. Yours might not, but mine were, you just have to check.
That was about 35k ago and all is well.....knock on wood!

If you are using the same housing, ring and pinion and carrier just reuse all the old shims, tighten the pinion down using a new crush sleeve to 16-29 in/lb and torque the bearing caps down (aarows pointing outward, on the same side they were) to 77lb/ft and youre good to go.
you will need a lb/ft torque wrench and a bram style 1/4" drive in/lb torque wrench with a 1/4-3/8 and 3/8-1/2 adapters so you can use your 1 1/16 socket to check turning torque of the pinion

Hey can anyone out there help me convert in/lbs to ft/lbs? My torque wrench wont go low enough in in/lbs to set bearing preload and i cannot find a beam style torque wrench anywhere in town. I figure if i can convert in/lbs then i should have it. I have to be between 16- 29 in/lbs i was going for 23 in/lbs so if you guys can help me out id be very grateful. thanks

alright thanks, ill go buy one tomorrow. A friend let me borrow his smaller torque wrench which was digital as well and that thing would not read at all, it would skip from 16 to 40 and higher it was hardly consistent at all, so as a result i messed up my ring so ya most definetly appreciate the feedback and ill give it a whirl tomorrow morning. later
