On my w123 wagon. I noticed 6 months ago one side was about 1/2 an inch lower than the other. I knew it had to be a bad sphere. Jacked up one side and slid a home depot paving tile under the tire, then the other. Kept the jacks about half way up and put jack stands on both sides, and wheel chocks. Loosened all three crowned retaining nuts, but left them on. Loosened the hose connection and bled off the fluid into a oil catch pan. Loosened the hard line and bled that. Removed both, then removed the sphere. Installed the tested junkyard sphere, added FEBI fluid and cleaned up. About 40 minutes including talking my sons 7 & 8 y/o thru the job and clothes change/body washing.

Nice work. How's it ride now?

Don't they both get the same pressure from the pump?

yep- but if you have one bad side "the boat will list" ever so slightly to one side- the bad side. It was between 1/2 and 3/4 of an inch. Enough to notice for someone sharp. The passenger side sphere I removed was completely worthless, the drivers side was doing all the work. May not be that way in every case, but mine was that way. I captain/maintain/fix a 22 year old 65 foot sportfish fulltime and have a keen eye for discrepancy, and I was guessing- but I guessed correctly.

I don't think I would have guessed that one correctly. Pretty slick.


If you revved the engine long enough before you parked, it would not have been as noticeable, right?

I can see how after a 'bounce', it won't return to the same height as the working side, but parked and then pumped up it should rise (I'm lost...), right?
