Creaking sounds from suspension
 

My xA has ~100k miles, original springs and shocks. When I have passengers in the rear get out of the car, there is quite a bit of creaking from the suspension. I blame it on these passengers being overweight :rolling:

Any one have similar experiences and if so did you find a solution?

2006 xB with 52K miles...I've got a creaking from the back end also. Sounds almost like dry bushings but I haven't bothered to check. My guess is they can't be greased so I may shoot them with some white lithium spray grease and see if that helps.

Sounds bout right for an older car. IF this was an S-Class than it would be an issue. If its driving straight and fine without passengers in the back, then save your money or turn up the radio.
