Rear End Popping

I noticed somthing today that kind of has me worried. When i backed out of my garage and turned the wheel it felt and sounded like a "popping" noise came from the rear end. If you know what a truck sounds like if you try to turn really sharp on asphault while in 4 wheel drive, it was that type of sound. Anyone else heard this? car only has 1000 miles on it....hope i didnt get a lemon haha

Take it back to the dealer ASAP, it needs the limited slip additive installed. Mine did this early on last year but found a bad bearing as well and had to be rebuilt. Most of the common noise's from rear end are because of lack of or not enough of the additive.
Hope this helps.

Agree. ASAP. But see if can get to reproduce the noise first. Then have them get in the car with you.

Any resolution? Mine is doing this as well. Pops once when I start to back up and again when I start moving forward. Almost like the rearend is binding then unbinding.

There is a TSB per Chevrolet on the issue. It happens with both the corvettes and camaros. Something to do with the posi trac in the rear end. Easy fix, take it in to your dealer, tell them u know theres a tsb on it and the resolution is some type of additive for the rear end fluid. Dropped it off when they opened and picked it up around lunch. Didnt cost a dime. Hope this helps!!

So I went to the dealer today for the car's first oil change and brought up the issue of the popping noise. I was told by the service "advisor" that the tech looked everything over and checked the driveline. Everything looked normal and that a clunking noise is normal when a car is shifted from park to drive. I told her I have an M6, not automatic, and it "pops", not "clunks". I then asked if the tech heard the noise and she said no, but everything was fine. I laughed, took my keys back, and left. I have an appointment at another dealership to have this looked at. Does anyone happen to have the TSB# that applies to this? Thanks for the help!

PI0137A: Rear Axle Chatter Type Noise on Low Speed Turns - (Feb 24, 2011)







Subject:

Rear Axle Chatter Type Noise on Low Speed Turns






Models:

2010-2011 Chevrolet Camaro






Equipped with Limited-Slip Differential (RPO G80)




--------------------------------------------------------------------------------

This PI is being revised to add the 2011 model year. Please discard PI0137.

--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern

Some customers may comment on a chatter-type noise from the rear of the vehicle while making low speed turns.

This condition may be caused by a slip/stick of the posi-traction clutch plates. As the plates slip and stick, a jumping or jerking feel occurs, accompanied by a chatter noise.

Recommendation/Instructions

Important: Prior to adding the limited-slip axle additive, the bottle MUST be shaken vigorously for at least one minute to mix the additive thoroughly, then immediately poured into the differential.

Drain and refill the rear differential with new fluid, GM P/N 89021677 (in Canada, use P/N 89021678) and additive, GM P/N 1052358 (in Canada, use P/N 992694). Refer to the Differential Oil Replacement procedure in SI.

Once the differential fluid has been changed, the vehicle must be driven in eight tight figure eight maneuvers to heat the fluid and allow the additive to be worked into the clutch plates

Awesome, thanks! I'll take this to the other dealership. The funny part is, the dealership I bought the car from specializes in Camaros and Corvettes. Wonder how much $$$ they have cost less savy owners.
