Rear diff clunk when pushing Tahoe body side to side

[Dustin Jackson]

I’ve had a bit of a rear end clunk lately and after doing all my usual panhard bar clunk tests like rocking the body back and forth on the side steps or rear bumper I wasn’t able to replicate the clunk.

But by simple pushing on the side of the Tahoe I was able to have my wife replicate the clunk while I climbed under the Tahoe and the clunk seems to be coming from the pumpkin.

What does this mean?

Pretty much standard lateral axle play in the c-clips and side gears.

I don't think so man, I've had this thing for a long time and I've never had this. Maybe it's just getting close to needing replacing

Take the rear cover off and watch what's going on. Good excuse to put fresh gear oil in that pumpkin.
