9 bolt parts
I have a 3.70:1 yukon gears with a tight posi ! it was gone through about 2005? has a solid pinion spacer. it has some wine at hwy speeds when you hit gear float (little to no load its always made this noise, was told its the gear cut which makes sense as it ALMOST goes away with none synthetic oil) I would like 200.00 but would take offers.
I have two sets of 3.27:1 gears one is still in the rearend. posi in that rear works but not very well had just over 103,000 miles on it. open to offers
also will be selling my aluminum 1le 3rdgen drive shaft
