Having AWD issues?
AWD Center Carrier Mount Failure
I was just about to reply that the center carrier mount was definitely causing your problem when you posted that you removed your driveshaft and found it out for yourself. I just went through this with my 98 V70XC AWD too. I didn’t settle for leaving it out and wasn’t going to pay 1,100-1,400 at the Volvo dealer for a new one. The dealer will tell you that it cannot be fixed but I’m sure you know from reading here it can be.
I got a rebuilt one from Colorado Driveshaft www.coloradodriveshaft.com They are really great and make it pretty easy getting a replacement. They pay all the shipping both ways, and in the end you are only out $475 or so. Call them in the morning.
AWD issues – Diagonosing bad propshaft in xc70
holler1 » In my case, the front CV joint on the AWD prop shaft failed. However, it made a metallic pinging noise that seemed to come from under the console area, not a grind or clunk from the front. This joint seems to fail a lot and it is right at the back of the bevel gear. Mine threw a lot of grease onto the bottom of the car and I could see that it was misaligned; also it flexed when I pushed it. This CV joint can be replaced. I think any other propshaft problem would cause noise farther back. You might want to try just pushing up and down on the propshaft at various points to see if it is loose.
I’m not familiar with what a bad bevel gear sounds like.
WeAre06 » Removed my drive tonight and the bumping sound that haunted me for 2 yrs is gone. The rubber dampener on the center bearing was totally busted. Taking my time, the job took 2 hours. The only trick was you had to have a front and back tire off the ground at the same time so you can put the car in neutral and spin the drive shaft allowing access to all the bolts.
So I’m FWD drive for now and maybe forever…
