Accumulators

To anyone that has replaced their accumulators, how much did you pay to have this done? I need to get mine replaced and I want to know about how much I will need. Thanks.

I did the spheres on my S600 myself. Total cost $250.00 and a weekend of my time.

Cool, I wish I could do it myself but I don't have the tools, space, or knowledge. I'm guessing a shop would charge around $500 total... What do you think? Thanks!

Most people and repair shops have the Mercedes mentality. Mercedes = $$$$$$$$. Mercedes are like a well designed airplane. They are a pleasure to work on, but you do need a strong mechanical aptitude. I would guess the total job will exceed $1200 - $1500. A MB dealer could charge even more. Ask them! You should have lots of choices in the Chicago area. My 1997 S600 had bad accumulators and you couldn't tell it, because the springs were doing such a good job. When I loaded it with family, then the suspension sagged and then it was obvious. A good system will have about an inch of clearance between the top of the tire and the arch of the wheel well. Anything else I can do, just let me know.

Thanks for the info, I'll have to save up so I can get that done soon, it's really annoying me to the point that I don't like to drive the car for too long. The other item that needs replacing is the motor mounts, ever had that done?

I had to do mine last winter. I did other work but I think that doing just those would have been under $1000 at Mercedes Benz of Orange Park. If you go to a MB Dealer, enroll in th classic car deal. It gets you a more competive labor rate and a discount on parts. The dealer will also warrant their work so in the long run, it works out well.


Try to familiarize yourself with the job involved and then talk to the dealer's "classic car guy" before the fix to get a feel on how good they will be with older cars.


I think that Mercedes is attempting to compete with the after market shops for the older cars. They run the same rates as the shop I take my old Porsche and used to take my S420 too before it was destroyed last year in an accident.

Good Luck,

Mark
