Depressurising SLS

Aiming to fit 2 new air springs and Bilstein B6 shocks tomorrow. I've searched the forum and read the RAVE and it should be not too bad.

BUT, can anyone confirm the easiest and quickest way to depressurise the system? I've read once to back-off the air pipes at the compressor then re-tighten once empty.

Is it possible just to pop the air lines out with a heavy rag over them once the vehicle's lifted? I did this with my P38 and it was fine... bit of a pop but no drama.

When I changed the airbags on mine I jacked up under the chassis rails so the rear axle hung down - and bags were then extended .
Just loosened of the 10 mm nut on the pipe going into the bag from the compressor - and very little air came out .
I had read that you should cut the pipe as close as possible to the connector and then simply push the end of the pipe into the fitting on top of the new bag . The new fitting is tested and airtight so shouldn't be disturbed .
Straightforward job really .

Yeah, you can't just 'pop' them out - the stock ones are nut and gland type retained.

I'd just do as RAVE suggests and loosen the unions gently at the compressor. Don't overtighten them after as they bite into plastic and don't need a ton of force to be airtight.

There isn't a huge amount of pressure to come out anyway, just a nice controlled hiss.

Thanks for the advice.

After prolonged consideration, and a computer-based SWOT analysis, I punched a bradawl through the spring and it did the trick fine. It makes a small hole, so the decompression isn't too quick. No going back, mind you...

I bet we'll be seeing these for sale on Ebay soon:

"Taken off my Discovery TD5, in perfect condition whilst on the vehicle - £50 the pair..............No returns"

Come off it! That's a bit steep! I'd take £40.

bugger! wish i had known - just ordered one from paddock.

I had mine replaced at my local LR specialist and they used the very technical technique of putting a drill through them! Thankfully he'd stuck a trolley jack under the tow bar so it didn't land on the floor!
