[ragtop11]

I had no problems with my dealer, stopped by with TSB P10137C they looked it up,
ordered the parts, called me when they came in, made an appointment for the following morning, dropped the car off at 7:30am, picked it up at 2pm, work completed, no problems , no hassels.

2012 ZL1 here. Same problem. Dealer said they would use the same TSB to fix my car. Is this not the right procedure for a ZL1? Maybe just need a fluid change. My owners manual specifies the 88862624 fluid as being for the ZL1. So the ZL1 should be filled with this fluid already , correct?

#PI0137C: Rear Axle Chatter Type Noise on Low Speed Turns (Excluding ZL1) - (May 11, 2012)

Subject: Rear Axle Chatter Type Noise on Low Speed Turns (Excluding ZL1)

Models: 2010-2012 Chevrolet Camaro (Excluding ZL1)
Equipped with Limited-Slip Differential (RPO G80)

Attention: For 2010 and 2011 vehicles built prior to August 25, 2010, if the chatter noise you are experiencing occurs only in Reverse while making a turn, please review the latest version of PIC5424.
This PI is being revised to add an Attention statement and update the Recommendation/Instructions. Please discard PI0137B.
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
Caution: The rear axle seals must be replaced. The original seals are not compatible with the new fluid.
Replace both rear axle shaft seals with GM P/N 22798805 and drain/refill the rear differential with new fluid, GM P/N 88862624 (in Canada, use P/N 88862625). Refer to the Rear Axle Shaft Seal and Differential Oil Replacement procedures in SI. This fluid includes a limited-slip additive (friction modifier) already added. DO NOT add any limited-slip additive (friction modifier).

Important: Please advise the customer that once the differential fluid has been changed, it may take as long as 805 km (500 miles) for the lubricant to fully penetrate the limited slip clutch plates. During this period some chatter may still be felt on initial startup while making slow turns until the rear differential fluid warms up.

Note: DO NOT re-use the wheel drive shaft nut. Replace with NEW only.

I have already the dealership drain/refill the rear differential with new fluid and with the entire bottle of friction modifier additive.
Now what is become of my axle seals?
Will the dealership be following up before a major problem occurs?
How long before the seals fail? probably after my warranty expires

Make them change it again AND put in the new seals this time.
