Rear airspring access

MirrorSignalSwerve · Sep 2, 2009

Thinking of doing the soapy water test and replacing O rings on the rear air springs. I can barely see the the spring air hose through the gap in the wheelarch. Has anyone done this fix? Is it better to take the wheelarch liner off to get access. Can't see how I can do it otherwise.

If the O rings are shot I would think the airbags are too

. No need to remove the liner to replace the airbags, but I would guess that you would have to to replace the O rings unless you remove the airbag:doh:

For air bag replacement, do a search on An Idiots Guide

Did the front a couple of months ago and bubbles from the top of the airline indicated leaky o rings so I change em and they're fine now. Would do the same on the back and hope for the cheap fix first, but change them if necessary.

Symptoms are the car very slowly lowering, sometimes overnight. I'd describe the handling of the car as not so much positive - more like set sail for the general direction you want to travel and it will wander its way there! Have changed steering damper, suspect track rod end, done the tracking, checked tyre pressures. Shocks seem ok. Next is the O rings and then change the springs if I have to. All part of the fun of owning a P38!

You dont have to remove the liner, but it will give you a tiny bit more room to play with. You will have a job though as you have found it is really tight in there. There should be enough room to squirt in some soapy water with a squeezy bottle. My advice is that if they are not leaking - leave well alone, unless you have a new collet to hand. Because of how they are positioned the airline fittings on the back get cacked up and corrode. Mine fell apart when I came to change the springs last weekend, its worth noting that although the springs where knackered, the O rings where in tip top condition. If you are having sinking problems, its most likely that you springs are gone. Have a look at my post here.
