Team, Here is how I go about it... Buy a shim kit for the carrier bearings. The kit I like the best, I've gotten at Reider Racing. They have a Two part shell that you put the thin shims in the middle (it makes them easier to put in). Find someway to lock the pinion (flat plate with the u-joint strap holes drilled in it, welded to a bar/pipe clamped to the frame, leaf spring, ect. so there is no movement. Mark a tooth on the ring gear & the Two intersecting on the ring gear (some ratios don't matter, but it can't hurt). Mount a dial indicator on the housing, touching a pinion gear tooth, rock one way, zero the indicator & rock the other way. This is your backlash. Unlock the pinion, remove the indicator & rotate the ring gear a half turn & repeat the lock pinion & dial indicator. Your goal is to put the ring gear back in this spot (typically .006-.012) it is before you take it apart. Start with the shims that you have, on the same side they are on & see what backlash you get (many times it is close). Add/subtract Right & Left aiming for the number you had in the beginning & add .001-.003 to each side to preload the bearings, this will make getting the carrier a little tight going in. Adding to the Left will increase the backlash, subtracting will increase it. Tighten the carrier bolts each time you check (it can change the number) & rotate . Once you have the same number you started with your done. Others may have a different plan, do a little research. Lorne
