2000 v6 - grinding noise

[Cj13531]

I’m hoping someone here can help me out. I have a 2000 V6 (manual) and when I’m driving and let off the gas it makes a grinding sound that is louder the faster I’m going. But the second that I give just a little bit of gas, the sound goes away and comes back right when I let off the gas again. The noise only occurs if the car is moving.
I bought a new driveshaft that came with new yokes in hopes that, that would solve the issue but that has not done anything.

I made a video that can be found at

In the video it sounds like a howling sound, not the raddling that you can hear a bit in the video

For a rear end noise. Likely IF the sound changes with the application or reduction of power the problem is:

• A worn pinion bearing
• or incorrect pinion bearing pre-load.
• or excessive ring gear free play.

Note, with a stock style pinion crush sleeve excessively hard clutch dumps can cause the crush sleeve to crush more. Which will change the pinion bearing pre-load.

Thanks for the reply. I will definitely take a look at that when I get a chance
