Jeep patriot fwd to 4x4

I picked up a 2009 Fwd jeep patriot 2.4l automatic pretty cheap, and I want to do a conversion to 4x4.

Before I start, I wanted an insight in all the parts I would need. Including wiring and such.

Anyone wanna help me out?

Going to be very difficult.. You're going to need a lot of electronics, would be cheaper to trade in and buy a 4wd Patriot. I'm curious if anyone has even done this before?

Totally unrealistic to do. The cost would be astronomical you would need so many things to even get started. If you wanted 4WD that is what you should have bought. This isn't an old pickup where you throw a t-case and front axle in and maybe some suspension upgrades. You have all the drivetrain stuff plus tons of electronics.

Don't waste your time. Sell the FWD and buy a 4WD or learn to live with FWD.

Only 1 part needed,buy a 4wd vehicle and sell the 2wd vehicle.The only way it's going from 2wd to 4wd.

Besides the parts, you need software. the awd system in a patriot is very strongly controlled by the computer, and the brain is married to the vin of your vehicle. so even if you got all the parts in, you wouldn't have a working system as you couldn't update the software.

Dealer could flash it for the various updated controls but I bet it wouldn't be cheap.

I doubt that they would be willing to do it... too much liability to them.

By law they can not.

Never heard of such a thing. Dealers flash vehicles for updates and changes all the time.

Different conversation. Can vs will.

They can't re-flash your PCM with programs not specified for VIN unless it's a accessory option that can be dealer installed like DRL's,cruise control,or OE remote start as they are not VIN specified options.

Could you imagine the liability the dealer would have?

Lets say that I have a 4x4 patriot that was in a rollover accident... so instead of trying to convince me to get rid of it and buy something else... lets play with the idea.

So the computer would have to be reflashed?

where does a rollover 4x4 come in? as a spare parts car?

The parts that would have to be switched over:
transmission
Front drive shafts
center drive shaft
rear diff
rear drive shafts
the rear suspension/wheel hubs (if even usable on a hypothetical roll over vehicle)
wheel speed sensors for the rear tires (and wiring)


and I'm sure there is more, that's just off the top of my head,

you might be able to switch over the ECU as well with the correct software... but not sure how it would work in the new car.

It's just no going to happen,your driving a FWD car based vehicle.The amount of $$$ and time spent trying you could buy a brand new 4wd one and still have cash left over.
