2005 AWD Vibration

Hello all

Bought this 05 equinox about 6 months ago. After getting snow I was out driving and when the tires start to spin and AWD kicks in I get the really bad noise(vibration) from the rear. It sounds like when you screw a screw in with a screw gun and the bit jumps or the top of the screw strips, that sound it makes..like a impact wrench??? It only happens when the front tires spin and the rear try to kick in. The rear do kick in but it make that horrible sound..any ideas. I have to let go of the gas and try to go a again. It does no matter how fast I take of as soon as the AWD kick is??? any ideas???

I have the same problem! You described it perfect. Any ideas?? I think the back wheel's AWD is not working, sounds like it slips instead of engaging.

i get like a loud rubbing noise when theres alot of sno but im like 99 percent sure thats the snow in the rims

My '06 does the same thing. I do know the AWD is working through it though, just not sure if the noise is normal. Next time I'm to the city I'll ask the dealer about it.
Cheers

My 05 does the same thing to, I'm going change the fluid back there to see if it makes it any better, a little bit of noise is normal though. I know that there was a service bulletin on these to change out the rear clutch drum because of noise in the rear end.

I have the same problem with my 06 with 35,000 miles. Just started to make this grinding noise when the AWD kicks in. The AWD seems to be working just a grinding or slipping noise coming from the rear when it kicks in.

I know this is a old post, put I changed the fluid in the rear diff and about a week later there was no noise at all, fixed the problem.
