Rear air bag/solenoid leak?

[shagdrum]

My rear suspension has been dropping slowly. When I go out in the morning, the rear is dropped. Start the car, it inflates the rear bags and raises the car. no problems driving, just morning start up. I got a pair of rear bags from American air. Installed and lowered car, turned air ride on...hissing noise in the rear?!

Raised car back up, used the included kit to "re-seal" the solenoids. Reinstalled, and dropped...still hissing in the rear and not inflating. Hit the 90 second time-out for the compressor, still nothing.

Raised rear end back up, reinstalled original air bags (I knew they had a slow leak, but did hold air), lowered rear...still hissing and not airing up. Hissing seems to be coming from driver rear.:Bang

No hissing from the rear before I started all this...

What is the next step? I know the new air bags are not the problem, I am thinkin new solenoids are in order. Any input is appriciated.

One of the air lines on my Mark VIII was actually severed behind the back seat. Likely do to chassis stress, the metal cross bars behind the seat broke and the edge cut the air line.

So, climb into the trunk and see if you can pinpoint the problem.

Did you shorten solenoids and put new "O" rings on the outside of the solenoid stem with di-electric grease.

Yeah, I'll look... but if that was the problem, wouldn't it have shown up before I replaced the air bag?

just "rebuilt" the solenoids with the little kit that came with the air bags. Basically it came with "seals to reseal the 'solenoid to strut/spring' as well as the small one that seals 'line to solenoid'" and a new "collet" for where the solenoid attaches to the air line. There wasn't a replacement for largest o-ring on the solenoid (the one at the base of the extension at the top of the solenoid).
