My 350SDL is beginning to exhibit a single front-end "clunk" as it tops quick rises in the road (decreased weight on the front suspension) - has about 150k on it.

Has 2 year old Bilstein shocks, but has had no other front end work.

Can anyone start me off in the right direction- figured this is pretty common at this age (the car's, not mine :-)? I am looking forward, somewhat innocently, to doing some suspension work!.

Any advice on non-OEM replacement of bushings, etc (urethane?) to tighten up the suspension would be appreciated, as well.

As always, I really appreciate the knowledge base and your time, and assistance.
