Transmission Problem, 2000 4-Runner

[Mrat28]

I have a 2000 4-Runner, 2WD, 6-Cyl with 140,000 miles. No previous problems with anything.

Currently at speeds at and above 40mph, when foot is taken off the gas pedal, a loud internal hum with vibration down the center of the vehicle (Drive Shaft) is felt.

Replaced the Transmission fluid & filter. Replaced the Tranny Mount with no correction of the problem.

The engine runs fine and the motor mounts are good.

What else can I look for to properly diagnose this problem? U-Joints, Drive shaft alignment, CV joints, etc, etc...

Any help is greatly appreciated.

Thanks

First I'd look at the u-joints. See if they have grease fittings... Maybe that'd help. That's my 1st inclination, don't forget the rear-end.


Next I'd make sure the rear axle is full of fresh fluid.
