[W126 Coupe] MBCOUPES Digest, Vol 87, Issue 8

[Mike Valeriano]

In regards to the clunking noise my problem was the hydraulic rams.  The ram wasn't leaking, but the lower ball joint was worn and moved in the socket.  I have a long thread on benzworld about it.  You can buy the ball joint separately for around $200.   The rams are getting cheaper so it makes more sense to buy a new ram for $400.  I replace mine and the clunk went away.

Best regards,
Mike
