I have a 99 W210 Est. Rear suspension has developed an annoying squeak. Bushes seem ok. If it is the self levelling shocks am I confronting big repair bill? Is there an alternative fix with traditional shocks/springs?
The squeak is obvious around town, seems to stop under acceleration and at higher speeds ( maybe just can't hear it then ! ) Tried wd40 on everything but will retry with silicon lube..
I had the same problem on my W124 right hand rear recently. It squeaks when the suspension travels up and down. Went to the workshop to have it looked into.
The lower arm bush was changed. No more noise now. Didn't cost much to change either.
