well i put my 4.88s in the rearend and when i took the front apart water was in there from one of my seals leaking but im getting the truck on the road tomorrow

after waiting for the clutch disks for my rearend put them in and put the rearend together and the pin wouldnt fit anymore so i called yukon and they said that that is a common problem in chrysler rearends so i had to grind on the ring gear to get the pin to fit in

so if anyone is doing gears heres a tip
