I'm helping a friend set up his rearend on a 1978 Camaro. We are using the Yukon Instructions located here: http://www.pirate4x4.com/tech/billavista/PDFs/Yukon%20Gear%20Ring%20and%20Pinion%20installation% 20instructions.pdf
The problem is, reading the pattern and comparing it too the pictures is a little tougher than we thought. There is one thing we can see is the obvious development of a "half moon" on the coast side which indicates a pinion too deep. We can also see for sure its not too shallow by comparing the pictures to the install sheet. As we gradually go down, you can see the half moon start to turn into a oval like shape, but not so obvious like the picture. It doesnt change a whole lot on the coast side, but the drive side does slightly from face to flank. What should we do? Go as deep as possible until its too deep? Right now since the .043" started to become an half moon on the coat side, we went down to about .040" and the oval is back. Or is there a range that will be good?
