Can I modify a 2WD car into a 4WD?

Have you ever thought why 4WD cars are better than 2WD cars? 

4WD cars are better than 2WD cars as they provide a much comfortable and orderly function and a safer ride all along. But what if you have a 2WD car. Can you modify a 2WD car into a 4WD car?

Let us know the same in the following paragraphs.  

2wd into a 4wd – Whole Story

It is possible to modify a 2WD car into a 4WD car, but the process is quite complex as well as costly. A 4WD vehicle has much more energy than just a 2WD vehicle. It has superior off-road functionality, performs admirably on slick surfaces, and has faster acceleration. Even farther, a vehicle looks steadier as well as its dynamics enhance whereas the vehicle is on route. The mechanical and fully automated transmissions of 2WD as well as 4WD are similar, but modifying the above by itself will not convert it into the 4WD. 

Every components you configure must be in perfect shape or they will start underperforming a few months later. To begin, the axle must be mounted first. Front wheel arrangement is critical in 4WD vehicles, and the axle position cannot be adjusted. You would then need a knowledgeable welder who really can assist you to get the wheel in the right situation for maximum effectiveness. The procedure also is not a one-and-done task; it is based on trial – and – error process.

Now let’s talk if modifying a 2WD car into a 4WD really worth the cost, time and work?

It’s simply not worth the money as well as the work. At some point of time, you may believe that the task is worth it. However, the actual headache with procedure would be that users may require a full re-transmission of a 4WD frame, specifically the sub – transmission. There are numerous components to alter, which could cause additional weight of the vehicle, that might ultimately led to energy losses. Furthermore, replacing all of these 2WD parts will lead to engine realignment. The realignment must be precise or you’ll miss in order to balance the car, which will impact the performance. Some transformation kits require the complete suspension system, along with the suspended lower arm, to be replaced. Converting to 4WD in a vehicle equipped with a modern electric power transmission scheme may impair the outcomes of a transmitting software and sensors. This implies that computer systems and their components must also be replaced so that the car can function properly. 

Have you replaced every component and are still uncertain that 4WD will perform as expected or not? You might very well need to pony up and purchase a new or used 4WD. Several car manufacturers create their vehicles in a manner that allows you to transform a 2WD to 4WD without restructuring.

Here are few points to keep in mind before modifying your car from 2WD to 4WD -:

  1. Compatibility: Not all vehicles are 4WD convertible. The best cars for conversion are the one that already has a transfer case and driveshaft. These are the actual components  in a 4WD vehicle. These components distribute power to the front and rear wheels. If your vehicle does not have these components, it may be more difficult or expensive to convert it to 4WD.
  2. Parts and labour: You will need to purchase the necessary parts to convert your 2WD vehicle to 4WD, such as the transfer case, driveshaft, and other components. You will also need to pay for the labour to install these parts, which can be significant.
  3. Performance: Converting a 2WD vehicle to 4WD can affect its performance. For example, it may become heavier and less fuel efficient, and the handling may change. It is important to consider these potential impacts on the performance of your vehicle.
  4. Safeness: It is important to ensure the installing of all components is correct and that the conversion is safely done. Improperly converting a 2WD vehicle to 4WD can compromise on the safety of the vehicle.

2wd into a 4wd – The Whole Process

Wheel Placement

  • The simplest method for converting a 2WD to a 4WD is to add the front wheel to a 2WD or to put the 2WD body on a 4WD frame. If 2WD is already in good condition and everything you have to do is improve it, adding a front wheel will enhance its efficiency. To do so, you may require a well-maintained 4WD vehicle.

  • The tunnel is bolted into place on 4WD models, but spot-welded into place on 2WD models. Based on the building system of your 2WD, you may have to reduce your trans tunnel to make more room for the 4WD to be bolted in place. You’ll also need to make some changes to make more room again for transaxle. Cutting a hole to allow the shifter to pass through would be an excellent modification.


  • Given that the two systems have a similar construction, switching a 2WD transmission to a 4WD transmission is simple. A same spline connect the output shaft of the residential unit and the gear ratios. The 2WD shaft, however, is longer than the 4WD shaft. The 4WD vehicle features a transfer case once more. The 4WD transmission features a similar type of unit, but it has a transfer case, whereas the 2WD transmission does have a longer tail shaft. Both axles receive power from the transfer case. In a 2WD, the gear-shifting modules do not require a transfer case.

Transfer Case

  •   In a 4WD vehicle, the transfer case is located at the back of the gearbox. Check to see if there is a fake transfer case in 2WD vehicles. With the use of two shafts, the transfer case aids in the transmission of power from the gear among two axles. Additionally, it corrects any imbalance between the front and rear wheels’ RPM rates. A set of limited range gears may also be present in this instance to assist you when you deviate from the route. The gearbox must have a unique design as it won’t have a transfer case. There are automobiles with 4WD applications that lack 2WD analogue elements. Subaru and Jaguar X Models are some of these models.

 2wd into a 4wd – Parts Required 

Make sure to purchase the following components when changing a typical 2WD transmission to a 4WD transmission:

  •       Automatic or manual transmission
  •       Middle differential
  •       Front and back differentials
  •       Drive the Cardan
  •       An exchange case

The approximate expense in modifying a 2WD car into a 4WD car would range between $2,500 and $15,000. The wide range of variables decides the cost of the conversion. First off, the availability and price of the parts will depend on the brand and model of your car. For instance, Toyota offers cheaper parts than Mercedes-Benz. Once more, it will rely as to whether you purchase only brand-new components or obtain components from such a source 4WD. You will spend less money if you choose the latter.


In summary, while it is possible to modify a 2WD vehicle into a 4WD vehicle, it can be a complex and costly process that requires careful planning and consideration. It is necessary to weigh the potential benefits and drawbacks before making a decision. The price of the modification, when coupled to the worth of ones existing 2WD car, may be more than the price of a 4WD automobile. Once more, the procedure is not straightforward, and effective performance is not a given.

Before getting the procedure done, consult the best 4wd mechanic and you’ll be able to understand the whole scenario better.
