2005 Tundra Rear End Noise (3 Viewers)

[SAB]

2005 Tundra

4 inch lift


Would anyone be able to help identify the repetitive grinding/swoosh sound coming from the rear end of this Tundra.

The owner recently had all 4 wheel bearings, driveshaft, and control arms checked.

It happens at any speed and does not change if the brakes or e-brake are applied.

Tires are balanced as well. This has been happening for the better part of a year.

Thanks in advance!

Any changes made just prior to the start of the noise? Have you checked the condition of the oil in the diff? The frequency doesn't seem to match anything that's rotating though. More of a match for suspension movement. Like going over a series of dips in the road or something. Weird one for sure.
