So came home the other day and right rear was on the ground! Darn it. Blown shock... No difficulty diagnosing it, hole the size of a baseball in the boot. Fluid everywhere.... So ordered new one, and put it in, presto, fixed! Calibrated the air system with my IDS system... (That has paid for itself over and over so far). So, this morning, drive to work, and after shutting car off on level ground, left rear looks a lil low. Climbing underneath, shock is wet, but bag looks ok.. Do I still need to replace? I'm assuming its toast....

 

Hi Jim,

I'm a little puzzled what the fluid/wet has to do with it. It's air suspension. Where do you notice it's wet?

I'd give it a little time to 'balance' out after you had one or the entire rear elevated during the RR shock change. If after a week or two, it still shows low, and you can't 'dial' it out of it using your SDD (just give it an adjusted 'height' to compensate), then I'd start testing that shock for a leak.

 

The shocks still have hydraulic fluid in them as well as the air section, that fluid is leaking from the shock... On the right side, when I blew it out it was everywhere...messy!

 

Did that, it was still down. It pumps right up, but slowly drops over he course of the day...

 

Okay I see, so the damper itself is leaking. That makes sense why there's fluid in there. In the air circuit of the airbag there shouldn't be any fluid. I hope to find a drawing how the individual damper/airbag is constructed.

Yep, swapped it.. Rides perfect.... Now if I could only find the darn bushings for the front lower arms that always wear out..... Everyone keeps sending the wrong ones....they are squeaking and popping now....

 

I'm sure there's a thread about these replacement bushings in the X358 section.....look and ye shall find I'm sure


Good luck
