Default Driveshaft noise?

I'm getting a clunking noise (sounds like it's under the back seat)when I occasionally start from a stop on my green volvo. Also ,when standing still, foot on brake and shifting from Drive to Reverse I get a similar noise but not as loud. The noise sounds similar to a rusted brake pad or shoe breaking away for a drum or rotor. If the consensus is that it is the driveshaft what steps can I take to verify that it is the culprit and what are the repairs recommended? Thanks in advance for any input.

I would check all engine mounts first.

Thanks, Tech. The 3 motor mounts under the engine look fine (the passenger side was replaced last year as well as the top torque bushing) I lifted the car and had my wife shift from D to R frequently to see if there was excessive movement . All looked good. Any other ideas?

Then I would remove the driveshaft and test drive and see what happens.
There is allen screws front and rear. Also the bearing carrier.

Thanks, Tech. I've been working on removing the driveshaft this afternoon and can't seem to get the rear end separated. I separated the front and after the 6 allen screws on the rear were removed, I yanked on the shaft pretty hard but it won't budge. Is it supposed to separate where the white dot is on the photo? I PB blasted it and will try again tomorrow.

The photo is a little small but yes in that general area. If you have a brass hammer tap it a few hard times where where they meet. That might knock it loose.

Thanks. That did it, and the clunking noise is gone after I test drove it. I'm very grateful that you moderate this forum and that you are here to help.

Hey tech, I also have driveshaft related question. I just replaced turbo on my 01 v70XC and in process of removing it I took transfer case out and disconnected driveshaft to gain some room. I replaced turbo, smoke is gone but my driveshaft is very noisy now. I was wondering what could have gone wrong? Noise starts at about 40 mp/h and its unbearable, i cant drive the car. It was totaly fine before turbo replacement. Its too much coincidence that driveshaft is gonne all of a sudden. Are there any tips of driveshaft R&R?
