My wife's 1998 S70 has 75K miles on it and we have noticed a clunking noise in the front passenger side of the car. It has gotten worse over the course of about two months. It sounds like something is loose. Two weeks ago I changed the front rotors and brake pads and while looking around for what might be causing the clunking noise I noticed the left front cv boot was torn. I had that replaced at a local independent shop that specializes in Volvos. At that point based on information from this discussion board I figured the clunking was coming from a broken sway bar link. The mechanic also thought that was likely and confirmed that it would be an easy fix for me.

I ordered the parts from Eeuroparts and replaced those this past weekend but the noise remains. I'm thinking it might be the front motor mount. I looked at it while inspecting my car during my brake repair but couldn't tell for sure if that was the problem. I don't recall the mounts ever having been replaced. Does anyone else have any thoughts on what it might be? The noise happens as you drive down the street seemingly even without minor bumps in the road. It is particularly noticeable at 25 mph or so. It doesn't appear to go away when the automatic transmission is placed in neutral.

Thanks in advance for your feedback.

Regards,
Trevor

Have you checked your sway bar bushings? I just changed mine and everything quieted down. Links were fine. Just a thought.

My car just developed the same problem but sounded more 'metallic' than the swaybar link sound. Checked the front motor mount (the one to the left of the main engine pully) and sure enough rubber worn thru at bracket. A $28 part at FCP Groton...

What about the infamous front spring seats, are they blown out?

had the same noise in my 95 850 wagon and it turned out to be the spring mount as rule308 posted. i've read in other forums that some are defective

Hi laboy561...

Just wondering if you ever got around to adjusting your wastegate... you asked about it back on Oct 8th, but I don't know whether or not you read my answer to that post.

Trev,

Check the sway bar end link hardware again. After I did mine, it seems the hardware loosened up. I then double-nutted things and the clunking stopped.

Good luck,

Marty Wolfson
