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. So you also have to modify the load-bearing capacity of the other parts of the vehicle to bear the stress.
Opting to go with a solid front axle will be the easiest option here since it negates the need for all the extra components found on an IFS suspension.
The front differential will need to marry up with the front driveshaft that connects to the transfer case. Once 4WD is engaged the transfer case engages the front driveshaft to power the front wheels. If the 2WD truck is rear-wheel drive with a rear axle, that eliminates the need for a rear axle. The additional weight from the added transfer case, diffs, and other components will increase your fuel consumption and decrease engine performance.
The 4WD drivetrain has more rotational parts that all add weight thus reducing engine power somewhat. This means you will need to beef up the engine power to accommodate the extra weight.
Aftermarket exhaust, filters, and intake mods are going to be the first upgrades. Later you might want to look at some piston modifications. You will need to purchase a donor truck or do multiple trips to the junkyard for components.
Also, depending on the make, model, and sophistication level in terms of electronics will drastically increase costs. This project could easily run close to the double figures into the thousands if you are going to do it properly. In theory, if the 4WD truck was an older pre model and 4-wheel drive was a factory option for that model, you have a donor truck so that you had all the miscellaneous parts that this job would require, plus the fabrication skills needed, plenty of time, and a wad of cash you could do it, yes.
Your 2-Wheel Drive is most likely a rear-wheel-drive truck so you will require a new front differential and axle to deliver the power to the front wheels. The transfer case needs to be compatible with the transmission to bolt onto it since it functions very differently from a 2wd transmission. I think about the only 4 x 4 conversion that might make any sense whatsoever a full-size van since there are kits for doing them. Here we strive to provide the most accurate, up-to-date, information about the functionality, common faults and latest technology built into most 4 Wheel Drives.
Skip to content So you probably drive a 2-wheel drive truck and most likely not by the means to upgrade to a 4-wheel drive truck so you are considering converting your existing 2WD to a 4WD. Table of Contents. Are 2wd and 4wd Transmissions the Same? Big tire upgrades are the most effective way of increasing ground clearance.
