Did Zuk quote you before hand? I keep meaning to email him. PO didn't really change diff fluid and it needs bearings and stuff that goes over my head. His website is really impressive.
ZUK said:Your backlash was a super wide .024"......should be .006"
To bring backlash back in spec I loosened up the one side 10 full notch holes....tightened the other side the same 10 notches.
A paint test revealed that the contact pattern is extremely shallow. I am surprised that you did not break some pinion teeth yet. The good news is I can reset the depth to a much stronger depth. It should be quiet.
One of the big adjuster wheels was mis-threaded in the slot. Fixed.
ZUK said:I threw out your flange...it was badly scarred. They did not even set the pinion bearing preload anywhere near correct...they used too much shim. The bearings were basically 0 preload with a slight wobble. I removed about .006" to get some preload to show up.
Starting to tear into my truck to check out the damage I inflicted last weekend.
