I've been searching on this, and read a lot about the slip yoke. Not sure that's my issue, but I'll give that remedy a shot soon.
Here is my issue: When I put the truck into reverse and back up, it will roll about a foot or so, then its like theres a tooth missing in the the rear diff. It studders (or clunks), then goes on. I've only noticed this when backing up a slight grade, and after the truck has warmed up. Have not noticed anything from a stop in forward gears, like most with the slip yoke issue.
This is on a 2002 2500HD with Allison and 287,000+ on the clock. Alli was just rebuilt about 10,000 miles ago. Have noticed this issue for the past 4-5 years, but seems to be getting worse. Plus, we are towing a heavy toy hauler now, so I'm a little more concerned...
Appreciate any input.
