Rear Air Suspension - what do I need to know?
#11
I'll do the PCV one.
The bad news is I woke up this am and the *** end was real, real low.

OK. Not to panic! Same thing happened to me multiple times. A chilly morning... happens.... they sag.
1) after starting the truck, does it pump back up in short order?
2) no warning lights?
If so -- I'd bet you just need new airbags in the rear. The rubber gets small cracks/becomes porous. My 2000 had the original Rover shocks on it until this summer (20 years).
I got Arnott on mine and it's been stable thru the night since. In fact just went to a cabin where I left the Rover for 5 days in sub frozen weather and it stayed perfectly level.
I would not get Genuine Land Rover, and I would not get Dunlop. I'd get Arnott.

Actually pretty easy to swap yourself.

It pumps back up no problem.
EDIT: no warning lights
Honestly I'm going to run it like this for a while and see how it goes.
(then get under there with soapy water in a spray bottle and see what's what.
Obviously don't want to burn out my pump.
I'm about to take it on a week long trip and do so desert off roading in it!
Fingers Crossed.

Another trick. Try parking it overnight fully raised up -- ie in off-road height - if it sticks at that height and does not lower ...then probably there are micro cracks in the rubber where the spring flexes at normal height. BY raising, you are flexing a diff part of the rubber on the air spring that does not leak.
I repeated the above a few days in a row, note mine would only lower overnight at regular height (sitting all day it always stayed level, it needed a good 12 hours or so and cold (sub 40 degree F temps).

Hey @specops1526 - and sorry to thread-jack - but check out old BringATrailer listings (a few trucks have air suspension and people generally have good / decent underside pics). Like this one - is picture 147 what you're after? -- https://bringatrailer.com/listing/20...iscovery-ii-2/.

My old truck had SLS but I never really looked underneath the truck after I disconnected it and put in springs.
