crush sleeve eliminator isnt that great btw.

I only it used it once, the amount of time wasted to get the proper pre-load isnt worth the hassle.

I agree. As long as the crush sleeve was installed and setup properly the eliminator kit is not going to resolve anything. And if they can't get a crush sleeve setup correctly I would doubt they can get the eliminator kit setup right.

Had a friend capture the audio from the chassis ear and upload it to youtube.

Chassis Ear Dodge Pinion

60mph, whine is very loud in cab. On the chassis ear the transmission output shaft is just white noise, you can hear the whine when switching to the carrier bearing, but it is loud when switching to the pinion bearing pickup. When I lift of the accelerator the noise basically goes away in the cab, you can hear it change from the chassis ear as I lift and add back throttle a few times at the end.
