I have a '98 V70R AWD with 130K miles and yesterday my wife called me at work to tell me the car was making loud tinging sounds from somewhere under the drivers seat. This morning, I put the car up on ramps to take a look. I moved the tubular drive shafts ahead of and after the splined joint (center support?) and isolated the sound to the forward shaft after the transmission differential housing. When I rotated it back and forth it made a loud tinging sound. The same sound my wife describe whiling driving.

Does anyone have any thoughts on what the problem might be? Would it be okay to drive the car to the repair shop or should I have a flatbed pick it up?

Thanks in advance for your comments.

Good news. The rhythmic clanking noise was the front drive shaft universal joint.

Thanks to those that provided comments.

I have a V70 AWD (125k) which started out making a weird whirring noise at high speed, then progressively worse clunking until there was a definity rotational clunk which could be heard half a block away. Went through a lot of non-diagnostics looking for the noise before actually wiggling the drive shaft, and viola, there it was. (Dealer didn't find it, two indy's did, and neither of them thought it was a big deal, but that I should repair it sometime (fcp groton drive shaft $860). In the meantime, it has stopped rattling - one mechanic suggested that it's due to the rubber shrinking in the colder weather, and since it's been such a warm winter to date . . .
In conclusion, isn't the the worst that would happen is that I'd suddenly have a front wheel drive instead of AWD? I've heard that some people just take the darn thing out.

Any thoughts?

Have you wife follow you to the repair shop, just don't use the boost. Hopefully, just a bushing.
Let us know,
My R has 118K and I am just waiting,
