So... @dbbowen has exhaustively researched the T-case whine in his axle swap thread. All signs are pointing to this being an endemic issue with the Advanced Adapter part. A handful of folks have chimed in privately and in the thread echoing their experience with the whine while running this setup.
Seems the fix for eliminating the whine behind a 4l60e transmission is to either use the Marks version of the adapter, or eliminate the adapter and the split case and instead use the HF2A transfer case (with different marks/AA adapter, and part time 4wd mod). @TRAIL TAILOR and @Bullzi both mentioned utilizing the HF2A with non-whining results, and I’m sure @cruisermatt has some experience here as well.
Headed this direction in the future, so… is there any benefit to sourcing the HF2A over the HF2AV (viscous coupling) version? Seems the viscous coupler gets eliminated during the part time 4wd install, so wondering if there are other reasons to avoid. New driveshafts would be necessary regardless, so longer output shaft housing is irrelevant?
