The paper from the dealer has Part # 88862624. Also says that they drained and filled differential 3 times as per doc#3331992.
I'm not sure what that doc number refers too. But now that I think about it, my car only had 9 extra miles when I picked it up from the dealer. So there is no way they drove the car as indicated on the TSB.

*, that may not be necessarily true. I have seen previous issues with with GM posi rears that when the rear diff is drained, and the proper lubricant is installed the issue goes away.

9 miles definitely does not meet the tsb requirements, it is at least 40. Many dealers treat the ZL1 like any other Camaro and don't understand the differences. They probably put the wrong oil in to. I have had both the ring and pinion snapped and the tsb done the correct way.

Recommendation/Instructions
Note: Steps 2 – 9 MUST be performed two (2) times for a total drain and fill of three (3) times to have this procedure be effective. 1.*With original lube in axle, conduct Freeway Speeds for 10 miles to warm up lube. 2.*Immediately drain original lube and refill with fresh lube. 3.*In parking lot lock steering to the right, and then execute 5 Full Circles at (5-10 mph). 4.*In parking lot lock steering to the left, and then execute 5 Full Circles at (5-10 mph). 5.*Perform 4 Figure 8’s at (5-10 mph). 6.*Freeway Speeds for 20 miles until operating temperature is achieved. 7.*In parking lot lock steering to the right, and then execute 5 Full Circles at (5-10 mph). 8.*In parking lot lock steering to the left, and then execute 5 Full Circles at (5-10 mph). 9.*Perform 4 Figure 8’s at (5-10 mph). 10.*Immediately drain current lube in axle and refill with fresh lube. 11.*Perform Steps 3 thru 9 again. 12.*Immediately drain current lube in axle and refill with fresh lube. This procedure is only to be used for the condition listed above. *During regular maintenance, the fluid only needs to be changed one time. *The maintenance schedule can be found in the owner’s manual on pages 11-5 and 11-7. *For regular service the fluid is changed at 45,000 miles or 72,000 Km and for severe service the fluid needs to be changed every 15,000 miles or 24,000 KM.

Well that truly sucks....
Curious what the outcome of this will be. me being me, I will probably just accept it, which isn't the right thing to do. |

...you got to break the sucker in...it's synthetic lube, like as in the engine oil. It's friction inhibiting and long life service to the max. There is a specific amount of time that seating and break in can occur upon. You miss the window, you miss the boat. Guys, seat the reciprocating and drive assemblies with gusto, they will break in and seat. Drive this car like a Sunday driver and you may incure issues down the road.

Thanks for all the suggestions. I stopped by the dealer today and they said to take it back on Monday. They also said that the mechanic wants to replace clutches. I think I'm just going to ask if they can verify that the correct oil was used and if necessary to add the friction modifier suggested by jessrayo.
As for the car...when I drove to the shop...the noise was loud. But it's not really a moan anymore. Instead it is a "thumping" or "grinding" noise. Very hard to describe. Thanks again everyone!!!

...it can only be a few things...There is a quality control issue with the assembly of the rear axle<doubtfull>, there are quality issues with the parts involved<possible> by the comment of the last post. Some of the complaints are driver perception versus reality issues. If the noise gets worse, or more pervasive over time, then it's a mechanical problem.

I went out and bought Royal Purple Max Gear 75w-90 with friction modifier additive.
Is that one ok to use with the ZL1 differential? If so I'm going to replace the oil with the RP and then drive the car in the figure 8's as suggested. If that doesn't work then I will take it back to the dealer and start looking at my options.

I have had both issues you talk about, The moan while turning in the cold is the second thing I had done because it was done prior to the release of the service bulletin. Be very careful, there are two bulletins for the Camaro's one excludes the ZL1 the other is the ZL1, the # for the ZL1 is #PIP-5097. The other issue you have is the one I would worry about. I had the same thing and it was the backlash, it was off and they swapped the ring and pinion. After that it was quiet for awhile as far as the slow turning in the cold moaning sound, and the decel sound was gone (backlash). Later, the slow speed turning noise came back. The TSB came out so I took it back to the dealer and they performed it. Mine has been quiet ever since and I have 25,000 miles, both proceedures were performed between 3,000 and 5,000 miles. I understand wanting to do the bulletin yourself and if capable why not other than the cost. I would just make very sure you are using the proper fluids because there is definitely a difference between the ZL1 and other Camaros. What I was told about the moaning slow speed noise is that leftover lashing compound gets into the clutch packs and makes the noise. The procedure removes the excess to eliminate the noise, so changing the clutch packs may not be necessary. I will find my work order and try to provide more info. The other problem may be the Dealer, very few really understand the differences in the ZL1. They will try to treat it like a normal Camaro and make mistakes. Good luck! Found the work order, part # for the fluid was 88862624. I am not sure if the Royal Purple is the same as the GM 88862624 so it might be good to check that before you do it. There was no slip additive listed on my work order, I believe that is for other Camaros, unless it is contained in the 88862624 lube.
