Quadralift Question

Should the QL system remain totally static with the vehicle turned off?

I just happened to look out the window at a restaurant the other day and noticed the front going down right when I looked out. The Jeep had probably been sitting there around 5 minutes when it lowered, I was in NRH when I parked. I have also noticed a couple of times when I get in to leave, it seems like it's raising up to NRH.

Is this normal, or should I have the dealer take a peep?

Thanks,
NB

Re: Quadralift Question

Yes, should be static. Don't know why it would cycle like that.

Re: Quadralift Question

Normally dropping while the vehicle is off is a sign of a slow leak. But with it being a closed system you wouldn't think it could keep this up for long.

Re: Quadralift Question

Might just be a sticking valve and letting the air flow into the reserve or the rear suspension. How far does it drop has anyone measured the change?

Re: Quadralift Question

I like the idea of Quadralift, but the expense/complexity of the system scares me. I like to keep my vehicles well past the warranty period and I could only imagine what it would cost to repair the system on my own dime.

Have a lot of guys been having issues already? I know Land Rovers are known for having problems with their air suspension systems.

Re: Quadralift Question

Ditto. My concerns exactly. Is Quadralift an option or standard with Overland?

My current 2001 GC Limited is 157,000 miles...when I buy the 2011 I plan to drive it a full 10+ years. So reliability is important...air suspension makes me worry.

Re: Quadralift Question

This all has been discussed in great detail in the suspension forum. If you plan to keep the car many miles and years I would suggest you get the extended warranty if you plan to get the QL suspension.

It is standard on the overlands. Only a handful of the first built overlands didn't have the QL suspension. Those will be very rare and worth a lot of money in the coming years.

My guess is that the daily temperature variation we've been experiencing the last couple of weeks is likely causing the QL to make such adjustments.

I haven't noticed mine doing the same thing, but I also haven't had much opportunity to look at it after it's parked.

Please keep us posted.

Re: Quadralift Question

It is a closed loop system and not very hi tech as most may think, air compressor, 4 air shocks and pneumatic tubing, so outside air temp should not have such a huge effect as if it were on an open loop system using outside air.

The hi tech part are all the leveling sensors front and rear, I have watched mine very rarely adjust while running when I got out in very small increments.

If you have an air leak even in the off cycle it will throw a code.

Re: Quadralift Question

I've been watching it close and actually have not been able to catch it move at all since I posted this, so, I guess theres nothing wrong.

I jacked it up to OR2 one day and left it there for a while and measured the distance to the wheel wells, and it never changed either.

Oh and on the reliability deal, I knew as soon as I decided overland and QL that I would be buying a Chrysler extended warranty. I bought the Lifetime Maxcare yesterday, so it's their problem now, not mine.

Re: Quadralift Question

I was working in the garage awhile after I pulled mine in and the compressor activated and it slightly moved. I've seen mine do this twice, and figure its part of the auto leveling just resetting or something.
