Hello All! I drive a '98 S70 with 84K miles and need help diagnosing a problem I've been having lately. While driving around town if I hit even the smallest of potholes or cracks in the road I hear a loud "thump" from the passenger side wheel. Every little crack in the road sounds as if I've just plowed into a 6 inch curb! Going over speed bumps are the worst. Lately I've been coming to almost a complete stop before going over them. This problem seems also to be aggravated by cold weather, and sometimes lightens up once the car is warm. I'm trying to narrow it down between shocks, struts, or bearings? Anyone had similar problems?

If it does it over irregular surfaces, it may be the sway bar link, that's what failed on mine. IPD had the part reasonably cheap and instructions on how to diagnose as well.

sounds like the rubber upper strut mount is broken. Common failure at 75k miles in these cars, right goes out first, then left within the next 10k miles.

Ditto - the upper strut mounts are failing. If you just do the right side the left will go within 6 months. The part is about $50, but repair shop labor will make it a $200+ job.

It's your sway bar- IPD has 'em sale right now for $39 part#SN9492804

You better have that car checked or just trashed coz theres no need of driving junk around that is prone to harming other motorists.
Fix it or get rid of it...just quit driving around with that ol explosive bang...its bad for the environment too.
