I picked up a 2001 Disco with 97k on it at a real good price and did some maintenance on it. It is a SE model with the rear air suspension but not the hydraulic anti-sway system. Even with the vehicle sitting/not in use for a few days, the butt end did not sag, it kept air pressure.

I took it into the shop to have the front two O2 sensors removed as I was unable to get them out. Since then, the butt end now sags after sitting for a few hours like the air shocks are now leaking.

I am not very familiar with air shocks. Is there a proper procedure to put these trucks with the air suspension on a lift? I just wanted to make sure the shop's method of lifting it did not cause the leak to happen or I will have to go back there and have them repair it.

Truck drives fine and the suspension fills up right away but it does now leak after sitting. What issues can result if I do not fix this? Worn springs?

 

Likely, something was stressed a little that was not used to being stressed. I believe they are jacked up like any other vehicle, nothing special. Not necessarily their fault, unless they bumped an Air Line pretty hard while jacking/working on it. It may have also just been time for a line to start to leak. Might be as easy to fix as a loose fitting, or maybe a crack in a line. Could also be an Air Bag as they do eventually give out.

 

your front has not dropped because disco do not air suspension the front, just rear.

 

^^^^THIS.

Technically according to the manual and the instructions that come with lifts, you shouldn't lift D1, D2, RRC, or Defender by the frame. It's just slightly dangerous because of how close together the lift arms have to be. It won't hurt anything mechanically though. The shocks should bottom out (or the watts link will bind up) before the air bags stretch too far. Most likely they were about to go, and they stretch more than they were used to, but no further than they are designed to.

I've lifted my 1999 D2, 2003 D2, and 90 without any issues.

 

Thanks for the replies gents.

My next question would then be, is there any harm if I do not address the leaking shocks until spring when it is warmer out and get in the garage? Like, will it wear out the spring or something? It seems like it is mainly happening on the left side, not both and still drives great. It must be a real slow leak as the pump only turns on when the truck is first started and does not need to run during driving to fill it back up.

 

Not unless the leak gets so bad that the compressor is running a lot to keep the bags full while driving, because then, you run the risk of burning up the compressor from over use... or unless it gets so bad that the compressor cannot get the suspension lifted off the bump stops on the frame...

 

It is not air shocks, it's air springs.


Looks like good prices here:

I've not bought this particular part, but I've bought parts from this company before.
