I think your right and may be the reason why the bump-stoppers are completly worn out.
I know that the right front strut is leaking oil but the rear shock mounts are making a a lot of noise when the car is idling. I realized
used that when a rattling noise was coming from the rear. I looked at the rear shock and the noise was coming from the mounts vibrating.
I am still waiting the dealer to get my new bump-stoppers and will let you know .
