Andrew, The problem is that you risk damaging other far more expensive pieces of the system, like the control valve and the hydraulic struts, which now are absorbing all the road shocks that were meant for the spheres. -Max -----Original Message----- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of andrew strasfogel Sent: Thursday, April 22, 2010 11:23 AM To: Mercedes Discussion List Subject: Re: [MBZ] Changing 300TD air cells (accumulator spheres) - anyoneBTDT? I am not yet convinced without further inspection that faulty sphere()s is(are) the root cause of my jarring (as opposed to bouncy) ride. Don't forget that one of the two spheres I installed 18 months ago was new @$140; the other was used. I will remove and inspect both spheres, but if the "new" one looks good inside (compared to the other one) I won't replace it. Since the labor on R/R the accumulators appears to be easy/cheap/DIY I don't see the problem of experimenting. I will also, of course, check for leaks in the SLS and for correct operation of the rear SLS valve. Thanks for your concerns and suggestions.
