I am stumped I have an 03 Hummer H2 with 60K that randomly squats down when it sits. If i back it into my driveway so the front is angled down nothing, but if I drive it in so the back is angled down by the next morning its squatting. I went under the truck with a spray bottle and soap and soaked the airbags and didnt see anything.. Could it be a bad line and how hard is it to check them?

Thanks
Hutch

 

Just gotta soak everything. sucks. on the bags try getting the rear end in the air..lift it with a jack so it extends the airsprings then spray. mine was leaking in the folds and sealing itself when level. it only leaked when not level.

 

I had mine replaced for $500 with steel coil springs and I would highly recommend it.

 

My bags were about $165 took me 30 minutes or less to install myself. very easy. The bags are better especially if you tow. it levels the rear end when there is weight on it.

 

J/c - what does the compressor cost if it goes? (I realy havent a clue).

Had a great job done on my springs (had small leaks in both bags). I only tow my Tahoe Q8 ski so no issues yet . But my air suspension caused one issue after another, and when it went down the last time, it looked like a car from a WAR video and rode like a stagecoach, hence my choice of steel coils. Great ride, more dependable thus far, and no mo low ridah!

 

The compressor is alot of money. thats why when your bags leak you fix them right away. If you don't, and let your compressor run all the time to keep the bags inflated, you will burn out your compressor. There are many threads on this forum about this issue.

SAH2 I tow a trailer that is at my max tow weight when I go camping and wheeling about once a month. the compressor is a must for me to reinflate my tires, level the rear end and blow up mattresses etc. If I remove it, I'll still need to buy another air tank or something like that.

 

It is the bags or a line (I had both). Raise the bags to the extra hight and spray them again. Almost sure it is bags since they dry rot.
I replaced with new bags, hoping the compressor is still in good shape. So far so good.
I love airsuspension. I had it on my VW Touareg too. Great when towing

 

The spring kit $170... You can do it yourself in an hour. There is a YouTube video on how to.

if you buy this spring kit can you still lift the vehicle after? has anyone tried? i am having similar problems and also want to buy a rancho lift kit. does this converison kit screw with anything? do i purchase the kit that asks if you are running springs or air?
