Strange whine at 60-65 and 71-73 mph...
I have a TRE stage 3 tcase, an exedy stage 2 sprung clutch. Both have about 2000 to 3000 miles on them. Transmission has larger roll pins in the shift forks, and oem syncros in good shape. (also has about 2000 to 3000 miles on it.)
The whine appears under load, and when in neutral/clutch in from 60-65.
It appears under load from 71-73 mph.
I've done a lot of testing and I can say that
A.) The whine appears at both speeds regardless of gear
B.) If accelerating from 60 to 70+ there is no whine past 65mph.
C.) It is not like tcase death whine ( I had that, hence the TRE tcase...)
I am stummped and have no idea what this could be. It isn't very loud at all, but when I notice it I cannot ignore it. I changed by tcase fluid about 500 miles ago to redline shockproof heavy, but it did not help the whine, making me think it may not be tcase related. Any ideas? Transmission maybe?
Thanks guys!

I hadn't thought about the tires as they are reasonably new...like 5 months, and not terribly worn. I will look into that, and def. get an alignment soon as I will be ordering some GTWorx springs in the near future.

No, generally only aftermarket (polyurethane or solid mount) bushings cause some additional whine. I have the AMS mustache bar eliminator kit, which has solid aluminum bushings, and my rear diff will resonate (whine) between 55-60 mph and again around 75mph.
If it's been 25-30K miles since your last rear diff fluid change, you'll probably want to change it regardless, though.
