I have a 95 4Runner with procomps 4" Lift, and at the top of the intructions it says I may need a high misalignment driveshaft because I have a V-6. Ifigured this because i have a loud humming noise coming from under the body when I release the gas pedal , but it goes away when I re-accelerate. Please help?!

 

I get that vibrating too when I release the gas or put it in neutral going about 45-60mph.

I have a pickup 93 with a lift, but I don't think it's the lift. My driveshaft is in pretty bad shape anyhow.

I had to change the ujoints a while back because the noise was really bad. That pretty much took care of most of the vibrating. But the problem I described above is still there.

If you haven't done your ujoints do that....or your driveshaft might be unbalanced.

 

Thanks. I get the same thing when i put mine nuetral too. I will try that then see about a new shaft. Thanks!
