Curious why you changed the rear diff fluid already? I couldve sworn the manual says it's good for 50k MILES between changes. I know theirs no initial 'break in' interval listed in the manual for the diff.
I guess it's not a bad thing to do either...did you make sure to put a friction modifier in the diff too?
I wanted to get any break-in metals out.
Yes, I used the GM part #'s for the lube & additive.

What is the break-in procedure for a new set of gears?
All new gear sets require a break-in period to prevent damage from overheating. After driving the first 15 or 20 miles it is best to let the differential cool before proceeding. I recommend at least 500 miles before towing. I also recommend towing for very short distances (less than 15 miles) and letting the differential cool before continuing during the first 45 towing miles. This may seem unnecessary but I have seen many differentials damaged from being loaded before the gear set was broken in.
I also recommend changing the gear oil after the first 500 miles. This will remove any metal particles or phosphorus coating that has come from the new gear set.

How often should I change my differential oil?
For a normal, daily driven, vehicles we advise that you change the differential oil every 50,000 miles. For vehicles that are hard worked, such as trucks that do a lot of heavy towing, we advise that you change the differential oil every 15,000 miles.
The owner's manual says the Camaro SS don't have a differential cooler (not counting the 1LE Performance package).
& if you were to track or race the Camaro SS...change your fluid every 24-hours of usage on the track.
PS: I guess that is why the GM owner's manual said to keep the rpm's down to less than 4K & speed less than 130 km for about 2500 km, & not to tow or go road course racing yet.
