WK2 Transfer Case SWAP
 
I have a 2011 GC with the pentastar V6. I love everything about it, but the 4x4 option i got. it only has the Quadratrac 1. Has anyone heard or thought about swapping the transfer case out of a new wrangler into a grand. What would be the challenges besides possibly having new custom drive shafts made.

It would be waaaaay cheaper to trade in your GC for one that has QTII w/selec-terrain

plus i dont know about way cheaper. i got my laredo for 15,000.00 and any with quadra trac ii started at about 28,000.00. I have found the transfer case for a wrangler out of a wrecked one for 200.00 and the wrangler had the pentastar v6. i can get custom made drive shafts locally for about 400.00 a piece. trying to find if anyone has attempted it. or if it would work. if the output shaft on the tranny is the same. plus it would make my gc rear wheel drive instead of all wheel drive which i like.

In the 2-3 years I've been following WK2 forums I have never heard of anyone attempting this. If it were easy I would think someone would have done the downgrade by now.

You don't need air suspension to get QTII, although I don't think you can get QTII in the cost leader base Laredo.

Here are a few things to be thinking about:

You may also need to do something about the computer... unless you don't mind a continuous check engine light.

Will the chassis mounting holes line up or are you also going to have to fabricate a bracket?

Does that wrangler transfer case have an electric motor shifter? Dunno what it takes to make that work other than a switch.

Does that wrangler use the same W5A580 transmission? Its more about the transmission than engine. I hear the 2012 and newer Wrangler V6s have the W5A580 or a manual shift. Earlier models have something else.

Resale value will probably be scrap value, if you care.

has anyone swapped in a Quadratrac ii transfer case into a quadratrac i jeep. looking at my jeep the wiring is there for the knob inside the jeep and from the wiring diagrams online the wiring is there for the transfer case itself as well. my biggest thing is i want 4 low for weekend off roading.

The recent Wrangler and WK2 W5A580 transmission to transfer case adapters seem to have different part numbers. I dunno what makes them different.

WK2: 52108715AA or 52120015AA
Wrangler: 5210844AA

The intermediate shaft also seems to be different:
WK2 68078839AA or 6808564AA
Wrangler: 05179989AA

No, there is a thread somewhere a few months back with discussion. Thats a big job with the CAN bus, controller modules, and all.

Much less hassle and expense to trade vehicle for one with QTII. The wrangler thing may be easier as both those cases are relatively simple.

You can get a 2011-14 Laredo E with the Off-Road Adventure Group I which comes with QTII/selec-terrain. No Quadra-lift.

Re: WK2 Transfer Case SWAP
 
Again because of the price difference in the jeeps with the quadratrac ii it WOULD NOT be cheaper to trade the vehicle in. as i paid 15,000. for the jeep i have now and the ones with quadratrac ii i havent found for cheaper then 26-28,000. which is a 13,000.00 dollar difference.

So that being said i can get a quadratrac ii transfer case for 400.00. out of a salvaged GC. and my existing jeep has the wiring for the knob and transfer case already on the wiring harness. what else would i need to make it work besides the internal knob. i was under the impression that the main computer controlled the tranny as well, would i need the ecm from the salvaged jeep or could i get my current ecm reflashed. Or is there another control module that im missing.

Re: WK2 Transfer Case SWAP
 
There may be some confusion between Quadra Lift (air suspension) and Quadra Trac II.

There are two transfer cases, Quadra Trac I and Quadra Trac II. Quadra Lift has nothing to do with the 4WD system and there is no I or II associated with it..
