Hey guys any ideas on what would cause a knocking noise from the rear of vehicle when turning left only. Normally heard when making a left turn at an intersection or so and I'm off the gas.

Thanks

U-joint or bad upper ball joint?

Do you have limited slip diff?

06 did not have limited slip only stability control. I'd add look at lower control arm, brakes on that side (including emergency), and wheel bearings to bugnout's suggestions

U-joints were replaced about 15,000 miles ago. It doesn't have that chirping sound of a u-joint though. Hmm I'll have to check the upper ball joint. The rear control arms were replaced not to long ago with new ones from the factory recall. I checked the brakes but didn't inspect the parking brake. Thanks for the suggestions guys. I'll check those items out. I should get some audio of the noise I hearing to help.

Use a long pry bar on the ball joint that is on top of the diff. If it has over 100K, it will have slop in it. Replace with OEM only.

Hey dragging up an old post here but wanted to update on the knocking noise on my Jeep. After changing out the rear u-joints and checking the rear upper control arm I found out the issue. It was my muffler contacting the frame. Weirdest thing and explains why I only heard it turning left. Slight adjustments on the hangers and all is well now.
