Question Can the Quadra-Lift be replaced with a regular suspension?

Can the Quadra-Lift be replaced with a regular suspension? Just asking because I plan to drive this Jeep for a long time and next time this suspension stops working I think I will just replace it with a regular suspension system. This suspension has just being expensive and a pain the last few months.

Here is my story if you want to read it (long sorry):

October 9th 2014, I took in my 2011 Jeep Grand Cherokee to the Jeep service department (to the only dealer in town) because my Quadra lift stopped working. In addition I asked them to perform recalls P14 and p36, both completed without an issue. The diagnostic from the Tech mechanic was that the pump/compressor was bad so a new compressor was ordered.

October 20th 2014, I picked up the Grand Cherokee from the dealer, paid the cost of $2180.20 (part plus labor), tested the Quadra lift suspension, everything seemed to be working fine. The morning of October 21st I notice that my front suspension was sagging. Turned on the vehicle and the suspension went back to normal. The morning of October 22nd the same thing happened so I took it to the dealer where tech identified leaking lines to both front suspension air bags. So new lines were ordered for a cost to me of $309.55 (parts plus labor). I don’t think I should had paid for them since they were not leaking before but I just wanted my car back.

October 29th 2014, picked up the Grand Cherokee from the dealer after they replaced the lines. I went to test the suspension and it just wouldn’t do anything. The only thing it did was to flash the suspension button lights or give a message to service suspension.

Took it back in the week of November 3rd, don’t remember the exact day, tech checked it out, service advisor called me later that week saying that everything was ready to go. I get there tested the suspension and it does nothing again. They ordered a new compressor.

New compressor arrived on the week of November 17th but I was not able to take it in until November 21st. They finished swapping the compressor on the 28th (according to them it took them along time since I didn’t have an appointment and they had other cars to work on). Tested the suspension and again nothing just the flashing button lights and service suspension message.

December 1st, dropped the vehicle at the service department. They gave me a dealer car for me to drive (nice of them). Yesterday December 9th, the service advisor called me saying that they got it working but they are getting a suspension temperature message that they should have it ready today December 10th. Today I get a call, that they can’t get rid of the temperature message and that they are working with Chrysler engineers to get it resolve.

To be continued...

I have not heard of anyone doing that, all the parts are not available over the counter, you may need a donor vehicle. All the A arms and such are the same, but struts, shocks and associated brackets are different. Then there is the computer, its probably going to be throwing faults and warnings all over without a reflash and the program installed is based on the VIN... but I dunno. I guess we wait until someone tries it. Its been talked about now and again. But the better choice may be either a lifetime warranty or trade it for a steel spring version.

Sounds like the local dealer is not that experienced with the QL. You may have had a slow leak that eventually burned up the compressor.

Here's a thread with perhaps another blown compressor, although it worked again.

The most cost effective way to swap the suspension from QL to "regular" is likely to trade the vehicle in on a JGC that doesn't have QL...

Tell me about it.... if I had known before I would have gotten the extended warranty the day I bought the jeep (used). It cost me 2000$ to fix the stupid compressor that died after 30k miles (3 months after I paid 40 000$ for the 30K miles jeep).
POS system if you ask my point of view.

I am selling the jeep when that extended warranty is over. Not worth the trouble.
Reg shocks cost nothing to change, and springs last the life of the car.
That air suspension looks like a nightmare of money to keep working.

So far mine works.... I had overheat errors before it died.
Now I don't care, I have an extended warranty until 6/120k KM, so it can break as much as it wants, I'm not paying for it, but in 3 years, I'm selling that jeep.

The whole Quadralift idea sounds like a nightmare in general. So many things that can potentially break. Sure there are people who have the QL and have zero problems but then there are people who have a million problems with it. I'm coming from the JK world so my opinion might be bias but there are 2" budget boosts available for Wranglers for like $200. The idea of having a $10,000 QL option to raise your vehicle a whole 2" is cringe-worthy.

Unlike the JK, the WK2 is a road/tow vehicle with some off road capability. The suspension has to be sophisticated to not compromise road manners or Jeep wouldn't sell many. Its mostly German (MB) designed. Folks that want big tires lifted off road cheap and dirty monsters look at the JK, where those of us that to highway look at the WK line. There was a lot of discussion when QL first came out in 2011 and there are plenty of advantages for those that need them. Park level for easy entry/exit, ORAII level for changing oil without a lift, sport level for better handling and mpg.... If you are afraid of QL, just don't buy it. Its like a $1500 option on vehicles that its not standard.

I prefer to park in OR2 when it snows so I don't really use the park feature :P

You may want to talk to a lawyer who specializes in the Lemon Laws. You may now be over the hump of qualifying and might even get some of your repair money back.

This suspension is a real fiasco when it goes bad. I am glad I have Lifetime Max Care

IMHO, at some point any of those systems will fail in due time, unknown by each. Lifetime warranty may be a good choice.

You know the new Half ton Ram has these air springs in the rear.
Plenty on the road.
We have the 2014 Overland.
Suspension looks pretty simple to me.
But it's not leaf springs.
To be honest I don't ever plan to go off road with this.
But I could I guess, a little.

This Lifetime warranty seems much better suited to a fully decked out Overland or Summit which would hold its value more in the case of it needing a new engine 10 years down the road rather than cutting a check for "actual cash value". Anyone agree?

I think anyone with the QL suspension that plans on keeping the vehicle should consider the lifetime warranty. That's the main reason I purchased mine.

I'm a Jeep newbie with a 2015 Overland. How does one do this? Does the car retain whatever height setting the ignition is turned off at (unless overridden by the Exit/Entry setting)?

Yes it retains the height, I use ORA2 to change oil.. Convenient but I wouldn't crawl under without first putting some jack stands under.
