Not a good thought! Ok ok, enough with the negativity now, let us assume, for entertainment purposes, that you have a blank check and you were given the task of converting a 2WD to a 4WD. All expenses paid, just pull it off. Or you want to build one of those crazy competition trucks with roll-bars, huge spotlights, and massive chunky tires.
Well, in that case, you probably will be better off building one from scratch as opposed to buying one. We will need a donor vehicle of the exact same model as the one we are converting. This you could probably source at a junkyard for a lot cheaper than say purchasing a used one. Because if you purchase a used one, then you already have a 4WD and it negates the need to convert your existing 2WD.
Selecting the correct year model will mean the difference between a relatively electronic-free, purely mechanical build versus a more modern 4WD with electronic sensors and wiring harnesses.
These electronic sensors and wiring loom will need to be connected up to ECU and other complicated electronic management systems.
The older trucks will require a bit of metal fabrication and some reinforcement to accommodate the leaf spring and solid axle conversion. More modern 4WD trucks are a lot more sophisticated and complex in design. This is since manufacturers are constantly under pressure to develop more user-friendly, greener, and safer vehicles. So the modern 4WD will have features like traction control systems, wheel sensors, more electronic wiring, and sophisticated braking systems, and in the case of an.
IFS Independent Front suspension more complex suspension components. So once you manage to get the mechanical side sorted out, you now are faced with the electronic nightmare. You will need lots of customization to get the 4WD to actually function properly. So if you are going to pull off this project you are better off with manufacturers which are renowned for vehicle diversification.
This means they utilize the same chassis, drivetrain, and other components in models, types, and ranges. Manufacturers do this to cut down on costs to develop separate chassis for a 2WD vs a 4WD or to change the wiring harness to accommodate a specific model. They use the same components and simply blank off the parts that are not needed in the lower-spec models. Large manufacturers like Ford, Chevy, Toyota, and Volkswagen, for example, are renowned for doing this.
You will require the below but not limited to the following:. You get this to function correctly and we are looking good. What is entailed? Here you are better off purchasing or swapping the entire transmission with the transfer case from a donor 4WD truck since the hassle of opening the transmission to modify the box to accommodate the TC will be a headache.
Click here to read about converting a 2WD transmission to 4WD. The transfer case will need to connect the front and rear driveshafts to the front and rear axles.
The drive shafts will need to be balanced properly. If the truck you are converting was originally available from the factory in that configuration, then a few trips to the auto salvage yard or a donor would give you the major and miscellaneous parts needed to pull it off.
On the contrary, if the truck you want to butcher was never offered in 4WD configuration, you have a major design and construction project to embark on. The expense, time, and expertise to successfully accomplish this will be huge.
Due to the additional weight being added, the 2WD suspension will require a substantial upgrade. Here we are talking about front and rear dampers as well as leaf packs.
This alone will be a few thousand out of your pocket. The suspension upgrade is necessary to accommodate the additional weight from the transfer case, driveshafts, and differentials that have been added. This excludes the other miscellaneous components that will all add extra weight. By converting the vehicle 2WD to 4WD the weight will increase. The Competition Ford Super Duty vs. Louis, MO. First Name:. Last Name:. They are lighter and energy-efficient, as well as generally less expensive.
But their limitations are undeniable. Compared to the 4WD counterparts, they provide less power and off-roading capabilities. These constraints are particularly impractical for F After all, people love their pickups for their ability to steer through winter weather and haul sizable belongings. Another thing to keep in mind; your title will state that your car is a 2WD.
