So I have 2WD Jeep. Yes, I know. But I don't plan on keeping it that way forever so help a Brother out...

I need a shopping list, of those items that one needs to convert a a 2010 2WD JK Sahara 4dr into a 4WD Sahara 4dr. I know it is going to be long and expensive, but you climb a mountain one steep at a time and I would like to know what parts I need to obtain.

I also would like opinions on which parts you think would be better to buy OEM new or used, and which would be better to buy as a aftermarket upgrade (since I am starting from scratch anyways)...

I plan to use the 4wd version of my JK pretty much as I do now, as a DD and as realistic transportation still, but something that I could play around in during the weekends. So 35' tires, a moderate lift in the 3-4 inch range, and stock engine for reference.

I figure this way I can slowly acquire the needed parts as they become available and funds allow. Other than a few cosmetic changes to my JK, this would be the big ongoing project for me to work on the next few years.

BY then the kid will be taller, Wife will have a new car to drive, and I can change the Jeep from family-mobile to something just for me

Thanks

I sent you a pm but for some others here is a basic list and buy new or used
Front & rear drive shafts used
Transfer case used
4wd shifter new
4wd shifter cable new
Tail housing new
Input shaft new
For axle Dana 30 or 40 used
Regear the front if needed

You will need to decide if you are going to beef up the front axle while it is loose , labor will be cheaper

If it was not for beefing up the front axle it would have cost me around 1400

 

Someone on here is giving away driveshafts

 

hold on................................ a 2wd wrangler ??

 

Prolly not as easy as throwing parts. Yes shafts, housings , transfer case, axle assy , shifter , cable console , mounting plate , and a few uddah things ... but the worst of it all is it is going to need all the harness, inputs to the PCM as the Jeeps CaN BuS computer system needs to know whats goin' on.

Sure you can just convert an keep it manual but the esp and all the other mitigation systems in the jeep may produce undesireable results when off road. Me ... I would sell the 2Wd and p/u a 4x4 and build from there.

 

Totally wrong , the only reason to even hook it up to the computer is to light the light on the dash and to keep you from going to fast in 4wd low

The ESP is in the axle not the trans case

 

Not just "in the axle". Like I was saying the system monitors inputs to the PCM. Things like wheel speed sensors , throttle input from ECM , Steering input from BCM and trans and transfer case inputs from PCM.

Correcting for an erroneous driver input in 2wd or 4wd can produce two entirely different outcomes. When in 4x4 say with lockers on and sliding sideways to the left, the system trying to apply braking force to just the right front wheel to correct the direction. The system is in a sense applying braking force to all four wheels as the one brake is tied to the entire driveline through locked diffs and transfer case as it thinks it is a 2wd drivetrain and is applying max brake force to that right front.


"Electronic Stability Program (ESP) is a stability enhancement system designed to electronically detect and assist drivers in critical driving situations and under adverse conditions...automatically. Using signals from sensors throughout the vehicle, the system determines the appropriate brake and throttle adjustments for directional stability of the vehicle.

Electronic sensors are strategically placed in the vehicle, allowing ESP to analyze steering wheel activity, wheel speeds, acceleration and the vehicles' rotation about its vertical axis (technically named yaw). During motion, the collected data is continually compared to determine whether the actual course of the vehicle corresponds to the direction the driver is steering the vehicle. If not, ESP springs into action, correcting the vehicle's direction to coincide with where the driver is pointing it through a series of brake and engine interventions by applying brakes and derating engine output. The effect is to help correct oversteer and understeer and to coincide with where the driver is pointing the vehicle to help keep it on the road." - Source - Jeep a registered trademark of Chrysler Group LLC.


AND with two different programs (2wd Vs. 4wd) a 2WD Jeep now becoming 4WD may provide less than optimal results.

 

it's just a light dude.. i have a converted 2WD JKU. You're over thinking it.

 

Others have done it. Gather the parts, and have fun wrenching!

I saw a member on here, JnT just swapped/ or is swapping out his transfercase with a rocktrac one. Maybe he would sell you his old unit at a price worth shipping it to you.

 

Thank you , people love to post on things they have no clue
