Transfer case whine

[Kernal]

Lock the CDL before driving with a driveshaft removed (and set the Emergency brake before you crawl under the vehicle to remove a driveshaft).

I thought mine was the pinion/carrier bearings in the rear 3rd member. Initially changed my axle bearings in the rear axle, turns out they probably needed it. Didn't help. Eventually had the 3rd member pulled and there was blueing in the pinion bearing, and it was a little loose inside. Had all the bearings replaced, so now I've got all new bearings in the rear end. The noise is still there.

I'm back to thinking its the rear output on the t-case. I never heard this until I put newer tires on that are near silent. However I and part time converted, and when doing the 10%Under drive and part time conversion the output was pretty bad so I thought we replaced it. It being bad AGAIN after just three years and 30k ish miles seems suspect. I haven't thought the whine in the T-case was the same as the whine I was hearing at 65-70mph. I was used to noise in the t-case from my old pickup with dual cases.

I would definitely check your output though.

I will hopefully be able to narrow down the area of the noise with the chassis ears. I can run 6 microphones simultaneously, so will be able to cover quite a few bases to help me pin point.

So I just need to come visit you so we can take a ride in mine too and sort it out.
