Yes, the preload will change when you change the bearings.
The marked pinion depth is almost always just a good place to start. It's always been off by around .003 when I tried to use it.
Thanks. I guess being a first timer, I'm doing too much "internet research". After further consideration, I can at least install both races and the rear bearing without making things too difficult. I'll start redoing this in a few minutes...
Do you see any issues with my reasoning on the 0.020" clutch pack shim? The depth of the hub was 0.491", the feeler gauge reading averaged 0.021", which gives 0.470". Subtracting the Ford spec (?) of 0.455" leaves 0.015", which should be a bit on the tight side. BTW, the stock shim was 0.005" with the old clutches and steels.
Thanks for you help (and patience!)
