Wierd vibrations

Weird vibrations

I recently was getting vibrations around 25, 35 and above 60 MPH. It goes away as soon as I let off the gas. Also when I would put it into Reverse from either park or drive it would clunk and lurch a little.

I took it in and they replaced both u-joints, the rear u-joint was worn out. That fixed the problem but now I get a low pitch hum at 75 MPH and vibrations, but this time the vibrations stay even when I let off the gas. The vibrations and noise go away around 80-85 MPH. So I again had the tires the tires rotated and aligned. But no luck.

Any suggestions? Thanks.

humming noise

I have the same humming noise even after the u-joints are replaced coz I installed an after market ujoints, but when I installed the toyota ujoints the noise is gone but still there is a little humming noise coming from the rear and I am planning to take my 4runner to a differential specialist, I heard that differential bearings would be likely our culprits so we will see after that....

I have a 2000 4runner SR5 with 100000miles
