Knocking Noise From The Front Suspension Going Over Bumps on Volvo C70

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 I go over bumps or turn hard right the knocking noise starts. I haven't had it fixed yet.
Hear a rattling sound in the front right side when going over bumps.
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.
the struts are sound but that knocking sound prevails like something is loose.
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.
A bumping sound under the front passenger side
I thought I was the only one! Was just told the front control arm bushing is torn and the control arms need to be replaced ... for $937. Looking for a second opinion.
Thought I was the only one with this problem, good to know Volvo is aware of it--getting it serviced ASAP.
Still in the mode where I take it to the dealer every few months so they can NOT fix the problem
Knocking and shifting in fromt end at different times. Volvo replacing...stated they are aware of problem.
hasnt been fixed,yet
front right strut making a rattling noise. Had to replace them.
Volvo said I needed to lube front struts!! Cost $38, Still under warranty but out of 1 year adjustment warranty Ha!
Waiting for the dealer to admit that the vehicle has a problm and repair same
