Where does the clunk come from on a Chevy Silverado?
The clunk will appear to come from the front, under your feet. When upshifting from 2nd to 3rd or downshifting from 3rd to 2nd, the 4L60E transmission may clunk. In TSB 01-07-30-042B (Jan 16, 2004) GM has stated that this is normal and no service is required.
Why does my Chevy truck make a clunking noise?
Discussion in ‘ Chevy Trucks ‘ started by VnDrWLawnCare, Jan 4, 2009 . Hopefully someone else has experienced this problem and can help me out. It doesnt happen every time, but close to… when taking off from a stop i get a clunk noise from the rear end. It feels like it is loose or something is moving or shifting.
When does the clunk come back in my truck?
Enjoy your truck with extremely less of a clunk or eliminated for about 8-10 month. Repeat if the clunk come back. Last edited by starspangled6.0 on Feb 11 2012, 9:07pm, edited 1 time in total.
Why is my rear end clunking when I stop?
There’s nothing wrong with the rear axle, it’s the slip yoke in the rear of the T-case like Spitz already mentioned. There were multiple TSB’s for this issue which included an updated nickle plated yoke. Greasing it will fix it temporarily but changing the yoke to the new design will fix it permanently.

Why does my Silverado make a clunking noise?
The noise is from the yoke binding on the output shaft. When the axle moves it causes the yoke to move. If you install Caltracs you will still have times when the yoke has to move, though it will take a little more to get it to move that much. GM’s fix was a special grease. As I understood it, that works for a while.

Why does my Silverado Sierra walk forward when I back up?
When you accelerate, the leaf springs flex, and this lets the rear axle walk forward slightly, which in turn moves the driveshaft slightly forward, and when you level out your speed, it goes back to it’s normal position. Same thing when you back up, but in the opposite direction.
