In my opinion only, it’s not just the gears. 3 different sets by 3 different manufacturers and 3 shops. Either they’re all no different from one another, this is just common with all torque arm 9’s and/or it’s that TruTrac. The only parts that did not go back were the axles. Nothing obvious was found there. I do regret not at least having them looked at.
The FN988 is around $2800 with associated parts last I looked. Plus new axle and the fab work would be an extremely considerable investment. I believe I’d need both axles as if I recall correctly I have 35 spline and not the 31 needed for the 8.8.
I’d be happy to offer the car as a test mule for development to adapt the 8.8 
Coincidentally all three shops found things they did not like as done by the previous shop when tearing down the center. I was hopeful each time one found the culprit. |
Based on everything I have read it’s the gears. They are all noisy. Just some worse than others. Your torque arm with solid mounts may be amplifying the noise.
