At first we thought that the tech had forgotten to add the posi additive to the diff lube so I drained the lube, put in a 7 oz bottle of additive and topped off with the recommended gear lube. Made no difference at all.

Ted told me to put in two bottles of additive so I drained her again, put in 14 oz of posi additive and then topped off with gear lube, still no real difference.

Well, let me say that it made no difference in the popping sound but it may have made the posi unit a bit less stiff.

This is what has me thinking its something possibly to do with the axles. Again, I can not tell all the time but it seems to be coming from the right side of the rear end.

I can live with a stiff posi unit but when you pull into a parking lot and your $50K camaro pops and snaps like a POS its hard to take. Just want to get this popping noise fixed.

Ted did say he would take the rear end back and check it out to make sure its alright. Only problem is that I am in Montana, he is WAY back east. My Chevy dealer said they would not allow the car to sit at the dealership until the rear end got shipped back and then returned. Plus it would cost me nearly $1000 just to pull it out and reinstall it. Want to make sure thats the problem before I do that and likely find out the damn thing is still popping when I get done and waste a grand.....

If it is the axles popping, WHY are they popping. To me that tells me something is binding up to hard and it CAN NOT be good for whatever is taking that abuse every time it pops.

I talked to one fellow member that had a similar rear end set up but with upgraded 1400 HP axles and never had any popping.

Just a bit frustrating. I will give Ted another call and see what he thinks.

Any more thoughts are welcome.
