Thread: D2 SLS strange problem

go to off road height and test the bags with soapy water.

the compressor has had to work overtime to keep the bag with the hole inflated--

Have a look at the plenty of threads on here about leaking air bags. They do not last forever and almost certainly you have a leaky one which is causing the compressor to overwork. It's often really hard to find the leak.

Replace both soon - buy from UK and easy to do it yourself.

What he said ^^^^

You have leaking SLS air spring/s ... order a pair form the UK. They are cheap, and take about 20min/side to changout.

Forget about them then for anothe 8-10 years.

.... and the longer you wait, the more damage you'll do to the compressor.

99% of SLS drooping problems are leaks in one/both air springs.

As pedro says go to off road height and maybe even extend the bags further by jacking up a bit from there, then spray soapy water (spray and wipe works well) around the crease marks in the bags, thats where they leak most often.

Paddocks spares in the uk have reasonably priced good quality dunlop replacement air springs. Easy job to change them, lots of info on here search SLS sagging etc.

Most unlikely to be a more complicated solution than new air springs.

do the leak check!

cheers.

I had the same issue in January this year. Left rear kept going down over about 3-4 days and sometimes never.

The local specialist said no leaks first time it was inspected in December. The second time in Jan they found a slight leak. In fact they gave me the bag to keep as a spare as we know it can last 3 days. I had a new bag fitted the one side (Dunlop) Then a few days later it dropped again. It was recommended that I did both sides and hope it was not the compressor or valve block. The other side was conititec and new in 2009 according to my bills from the previous owner.

It became very frustrating taking it back and forth and the bills. Plus I was due to go on a road trip that week too, so they agreed to take the new bag back after a week and refunded and fitted coil springs with a one inch lift.

I may consider putting air bags back on at some point when im a little more flush with $$$.

That said the peice of mind with springs is priceless! The ride is no different. fully loaded with 5 passengers and gear it does not sag. I have a 7 seater but don't use the rear seats. I understand that SLS was standard for 7 seats for the weight etc.

Peice and mind of reliability with coils has won me over!

i had the small air tube rub through recently about 8 inches from the rear drivers side air bag which was only a intermitant deflation of the suspension it cost about $20 to fix it
