Thread: Should i or shouldnt i

Hi MarknDeb, I dont have air susp. but I was talking to a D3 owner the other day who said he was a specialist in this type of engineering and swore by it. Because it gives you choice in ride height Id be inclined to sort it out and stick with it. Im sure Harry at MR would give you good guidance.

Hi Mark;

I've got this same set up on my disco as you've just described , Coil Springs with Polyairs Bilstein dampers ,although I've not have any experience with air bag suspention , but I swear by this set up ,it's great for touring.

Hi Mark,

If it were mine, I'd change the air to spring.
That Caravan would be putting a lot of stress on the rear air bags, especially without a WDH

Cheers,
Ron

Kandy - the D2 doesnt have the same setup as the D3, it would be nice to have the choices of ride they do.

Disco_owner - do you tow anything heavey mate, this is where my decission will lay, Dwayne at MR is the one saying to run this setup and he hasnt steered me rong yet

Ron, good to hear from you on this, yes mate i would definately have to run with the WDH on this setup , the good thing would be i could set it all to work together and have best of both worlds

I would imagine that fixing the underlying problem with your SLS would be the better option and probably cheaper too, that's what i would do.

Sounds like an airbag or an airline has a leak, the faults would be because of things working overtime to keep the air in, fix what's wrong and in theroy the faults will go.

Mark;

The set up is ideal for Towing , often I tow a heavy trailer to the Tip , Just pump the your PolyAir bags and readjust the ride height. no worries.

Hi MarknDeb,
I have a 21.5 Lotus Sprint sitting up on 3 tonne simplicity suspension. It is about 2,500 kg loaded up. I have towed it about 15,000 klms with the SLS and 750kg Hayman Reece load leveling hitch/device. (Yeah, I know).

Put some very soapy water in a spray bottle and spray it all over the air bags, lines and fittings. Leave for about 3-5 minutes and look for a patch of tiny bubbles. This may identify a leak.

Both my air bags had a leak from the cheap stuff they put on the tread as a sealant where the air line goes into air bag itself at the top. There is a screw in setup that locks in the air line. Good place to start. A dose of Number 3 aviation gasket on the treads fixed mine.

Personally if any thing else in the SLS system on my Disco plays up then it is getting Lovell springs fitted all round with polyair bags in the rear. The last thing you want is no rear suspension on the side of the raod with the van on the back.

Also the shuttle valve error is ABS.
Pump relay open circuit, I believe is also ABS
Rear sensors - could also possibly be wheel sensors ABS

Just throwing in my opinion (not experience with air susp.) but Im with Redback, fix the probs. before going all out with alternatives (might save you a lot of dough). My understanding is the design (if all things are sound and a good service programme should complement that) of the air susp.system is such that it supports and enhances towing BUT I have no experience only word of mouth and its all good BUT I appreciate the view that a system failure in the middle of nowhere (dud compressor, airbag blowout/leak etc. ) would be a real bugger or worse BUT so would an alternator / starter motor etc. SO get everything working top notch and enjoy the ride.
