2wd to 4wd conversion (Trading/Selling not an option)

Scar0 · **Posted:** Fri Jan 29, 2016 11:26 pm

lfhoward is correct. VIN specific programming is in almost all the electronic components.
A dealer can change the VIN in a PCM, but with that change, it will also be programmed with the VIN specific programming.
IE it will be programmed as a 2x4 and the 4x4 programming will go away.
A dealer will not/ can not change VIN specific programming. It has to be done by C.J.D. Corp engineers, and they will not do it.

tjkj2002 is also correct. The harness which controls the 4x4 X-fer case and switch is part of the main body harness. It would be more of a nightmare to try to add to the harness then to replace it. Either way you would basically have to strip the rig down to metal to do it. But without the computers talking to make it work, whats the point?

But it is possible to convert it to 4x4. After spending all that money to convert it to 4x4 why would you sell it. I at least drive cars until its junkyard time.

You'd be surprised. A lot of people like to start projects then dump them, or do projects just to get rid of the finished vehicle a few years after completion. There are many of us that won't give up our rigs (TJKJ is probably one of them...), but there's more that just build it to have it, then move on to something else.

1) Its just a computer, you can make it do what you program it to do. IF YOU Know how to change the parameters.
2) so you can find every part at a dealer could you not? Get what you need and install it all. I work on rv's have changed harnesses on new mercedes sprinter vans because rats chewed through wires. Hard work but somebody has to do it

Apples and oranges, changing a complete wiring harness on a Sprinter is not even close to the same as swapping out everything in a vehicle, we're talking everything just to convert to 4X4. Then if he ever goes to sell it, no one will want to touch it due to VIN saying 2 wheel drive etc.
Its not a feasible project really

I was bored today at work so I looked up some part numbers to see how many parts would have to be switched. On a 2008, apparently the IP harness is not coded by 4wd/2wd, so in theory the connectors for the shifter and control module are there, just taped back. The only harness that is coded by drive type is the engine/trans harness. Furthermore, due to the TIPM archetecture, the ECU and ABS do not have 4WD specific programming, it is all contained in the TIPM and programmed at assembly. I don't think the dealer tool would be able to change that, but even if it did, they would probably not do it due to the liability. I do know that the engineering software can though.

Short summary is the only harness/electrical you'd need to swap/add is the engine harness, switch, and control module, however without the engineering software, you won't be able to use it. You can try to see if a dealer tool can do it, but I don't think it will.

If you do you would be the first person to swap 4wd into a 2wd KK that we have heard of. I've seen it done with the XJ Cherokee but not on a Liberty. Please document your project as you go, so other 2wd KK owners will be able to follow in your footsteps if you are successful. :JEEPIN:

Your not going to get the programming unless you buy the starscan and buy the VIN specific programs from Chrysler(will need the correct 4wd VIN).That alone is about $3000-$10,000 and that is not even getting into the actual computers and harness that is needed besides the actual 4wd mechanical parts.

By the time your done you've spent the same amount of $$$ if not much more to out-right buy a 2 4wd KK without trading the 2wd in.

Efren_Hinojosa owns a CRD KJ not a KK.

Ah. I didn't catch that. And Coast2Rockies is the original poster.

tommudd · **Posted:** Sun Jan 31, 2016 12:22 am

How many poor KJs / KKs are sitting where someone thought they could swap in an engine, change from 2 wheel to 4 wheel etc over the years
Lots that I can remember and my memory is not even good any more :-)r

lfhoward · **Posted:** Sun Jan 31, 2016 9:50 am

Definitely more V8 swaps have been attempted than have been successful! I can think of one or two running V8 KJ's but neither owner claims that it was economical or easy, and there had to be some expensive custom programming to make it work.

Naw, They probably ditched the computers all together and went totally old school.

Like a distributor, throttle cables, vacuum lines, and a carbeurator?

I know of two that were started to go old school, neither was finished as of today though
Couple tried to connect everything up but costs a lot of $$$$$ in the end

I know of 3 successful V8 swaps.

2 used the 4.7 V8 and did 1 or a few posts then disappeared.The 3rd used a 6.1 HEMI but you will never hear about it,took all I could to get disclosure of it since the customer(assume it was sent to the middle east) did not want to advertise it anyway.I know the builder that did the 6.1 HEMI swap in a KJ and the #1 must is it has to be SFA'd(no clearance otherwise for the oil pan) and was done using a stand alone PCM tied into the OE PCM to "fool" the OE PCM that the 3.7 V6 was still in place and cost well over $30,000 just for the engine swap not including the SFA conversion with D60's.

So see , .....very easy and cheap to do

As stated I cannot sell it. I have a plan to buy a 98 grand Cherokee with the 5.9V8. Not too bad for 3 grand. But turning this KK to a 4wd is still on the list.
