My final setup was to add another thin shim to the s2 side of diff to slightly increase preload and backlash.
Pulled the input and pinion shaft out... checked preload and it is around 35-40 inch lbs which is about right for FAG bearings?
Rechecked my pinion depth and I am within 0.01mm of spec.
Checked backlash and it is slight larger.. took 6 readings and the average is 0.158 (spec is 0.15)
The book says you dont need to check the pattern.. but here is mine. Not sure if I am using too much compound. I engage gears, and then use a thick leather glove to brake the drive flange while rotating the input shaft forwards, and backwards.
My patterns dont look anything like the "footballs" that the websites and youtube vids mention.
But according to the numbers, I think it should be right?
fyi - I only apply the compound to approx 5 teeth on the CW.
