Hi All: What can I do to quiet down the suspension on my wife's 2000 V40. When I hit bumps in the road I hear a metal on metal sound coming from the front and the rear. Thanks for ANY ideas!!!

 

inspect your springs! most likely you have a broken spring where the last 3 inches or so of the top coil has broken off.

 

Good possibility, plus any number of bushings can fail to the point where you're getting metal-to-metal contact. This would include the control arms, the sway bar bushings and link bushings, and strut / shock bushings. There are a lot of bushings that can do what you describe. Normally these are fairly easy to spot visually, though it might require pulling the wheels to get a better look.

 

Gen 1 S40s are notorious for having the ends of the springs break. If it happens in the front, it will most likely also damage the bushing/bearing - which btw, is unique to the 2000s - as the design changed for 2001 to 2004. as noted the 2000's strut bushing/bearing is a weak design and can cause the metal/metal contact.




Here's a couple pics showing the difference between the 2000 S40 and the 2001+ Strut bushing/bearing and a pic of a broken coil spring. Note you can upgrade the 2000s to the 2001 design but there are different part numbers for the strut components (including the strut, spring, bushing/seat/bearing ) so you'd need to build a full 2001+ strut.
