I was sitting in my 2003 CL600 the other day tuning my stereo and I noticed every 7-8 minutes the passenger rear would suddenly drop. I have noticed this a couple times after starting the car and putting it in gear that the passenger rear would drop. Its not dropping down low, just stock ride height. I have gone out of the car to watch it and it seems that the shock (or spring) slowly lifts while running then quickly goes back to normal height. If I use the suspension raise button the car raises and drops as it should and the car never drops down even when sitting for a week or more.
So this had my curious, is the valve that controls the hydraulic fluid in the strut itself or is there a distribution block I need to replace?
The struts were all done 1.5 years ago and the ABC pump is under a month old as is the line that goes to nowhere. Is there yet another part I have to replace or do I have to replace that passenger rear strut again? Also since the system runs at nearly 3000psi what is the proper way to relieve pressure before replacing the part?

Got it figured out, replacing seals for the rear valve assy.

Hi Laser,

I was just reading your post. Just purchased an 2002 CL500. I have a few questions.
Is there a valve assy for FRONT shocks and REAR shock?

Did you replace the seals yourself?
Where are the valve assemblies located and how did you bleed the system.

Thank you

I sold the car. Dunno what new owner did with it. I think he wrecked it.
