Re: 4" lift driveshaft problems 88 blazer

check the pinion on your rear diff i know this doesnt really pertain to your lift kit but my old 86 used to do that. Driving it would be ok but coasting the rear end would scream and i had all sorts of driveline chatter. found out one day in a home depot parking lot that my pinion nut had backed off some. i am unsure how but it did. I put locktite on the nut and never had the issue again.
