OK, I have been reading the threads and how-to articles on setting up the rear end. I think I have it down. But I have a question on the shims themselves.
People are talking shim depths like .020, .030, etc.
When we took my 8.25 apart, we found a .068 shim under the inside pinion bearing race. That was the only shim in the case. Unfortunately we didn't expect it to be under the race, so when we were knocking the old race out, we were actually hitting the shim...so it is screwed.
Now, I have a set of 3.55s to install. They are from a 2004 Dodge Dakota V6. They are clearly marked (both ring and pinion) with -0820 (or maybe it's 0280- ). I assume this means .082 is a depth, and therefore a good starting point for shimming.
Now, the Motive Master kit I purchased has 6 shims for a combined 0.060 in total thickness. Nowhere near enough.
I stopped by the dodge dealer and they list the case shims from .020 to .038 in .001 increments. If this is the case, does dodge stack them under the race to get the right depth, or is my assumption of .082 way off? It just seems like a lot of shim. There is nothing in the Mopar system regarding pinion shims..only case shims.
If it is accurate, is it OK to stack two shims under the race to get in the ballpark, then use the pinion shims to fine tune it? I don't want to have to knock out the race once i get it installed.
Maybe use the old race and bearing for the test fit, as I have read to do?
Is there a good place to purchase those thicker case shims in a kit? The dealer wants $6 PER SHIM.
