Problem Description and Possible Solution
Knocking noises going over bumps can be caused by worn sway bar end links. These end links have small ball joints that become loose and rattle. Replacement is the only fix.

When going over bumps, my car makes this "chinking" sound (like shaking a bag of coins). The dealer first couldn't hear the problem, told them to roll down the window! They found a broker link in the sway bar and replaced that. Still didn't fix the noise. They just replaced both front stuts. Much better, but still making the noise; dealership is trying to duplicate.
While watching my daughter drive away down I lane...I could hear that terrible clanking noise. I initally thought "CV Joints/Boots". Dealer determined sway bar links failed inspection. Replaced both front sway bar links. Cost of one sway bar = $82.62, Labor to instal at Volvo Dealer = $94.95. Total Cost to replace = $260.19.
