I regeared my Tahoe to 4.88, replaced the slip yoke, checked the rear brakes, and clamped the leaf springs...but I'm STILL getting this clunk when I roll forward from being stopped. Can anyone help me figure this out? Thank you in advance.

 

Did you pack the slip yoke with grease? This will usually stop the clunking.

 

how bad of a clunk? did you get the pinion nut torqued properly when you regeared?
