PS: it's not the rear end - I just had new ring and pinion installed which did not fix the growling sound.So my truck has a loud growling sound on the hwy around 55mph whenever I let off throttle. It improved with a new driveshaft, but did not resolve completely, so I'm thinking it's the T case rear output shaft bearings. I don't have the time or desire to rip the t case apart and rebuild it with new bearings/seals. I'm planning on going this route to circumvent the inevitable oil pump grinding problem.
My only question now is should I keep the electric shift or take this opportunity to switch to a manual shift T case?

The truck is on 4 inch lift, 35's, stock motor, and will not see extreme rock crawling. I'm fine with the current low gear ratio and don't want to fork out $$$ for an Atlas.
Thanks for any opinions.
