Can a car still be driven if the transfer case is damaged?

A car with a damaged transfer case can still be driven, but it cannot switch to four-wheel drive mode. Generally, it is not recommended to continue driving, and the vehicle should be taken to a 4S shop for inspection and repair as soon as possible. Only four-wheel drive vehicles have transfer case components, which are very important for such vehicles. The transfer case is a device that distributes the engine's power, directing it to the rear axle or simultaneously to the front/rear axles. Below is an introduction to the transfer case: A part-time four-wheel drive vehicle is typically a two-wheel drive vehicle that can switch to four-wheel drive for off-road conditions. The part-time four-wheel drive transfer case is a purely mechanical device. When engaged in four-wheel drive mode, this type of transfer case rigidly connects the front and rear axles, allowing for a 50:50 power distribution between them, which is highly beneficial for improving the vehicle's off-road capability. Due to its purely mechanical structure, it offers high reliability, making it crucial for vehicles frequently driven in remote wilderness areas where rescue is scarce. Even today, many hardcore off-road vehicles still use this type of transfer case.
As someone who has been repairing cars for many years, I've seen quite a few cases of transfer case failures, especially in off-road vehicles and SUVs. This component is the core of the four-wheel drive system, responsible for distributing engine power to the front and rear axles. If it's damaged, the vehicle might still be drivable, but the outcomes vary widely: with minor issues, only the front or rear wheels may work, allowing short-distance movement on flat roads. However, when encountering turns or slippery surfaces, uneven traction can lead to skidding or even rollovers—a friend of mine experienced this, ending up spending over ten thousand yuan on transmission repairs. The risks are too high, including increased fuel consumption and potential chain damage to other parts. I strongly advise against taking the risk; get it repaired immediately or call for a tow truck. Don't neglect regular maintenance—periodic checks of the four-wheel drive components can prevent such troubles. After all, safety should always come first.
After getting used to driving a 4WD vehicle for daily commutes, I once experienced a transfer case failure. The car was still drivable, but its behavior was strange: wheels dragged during acceleration, unstable steering in turns, feeling like sliding on ice. I stubbornly drove some distance to the repair shop, where the mechanic warned it could wear out the transmission and might even require a complete overhaul. When the transfer case fails, power distribution goes haywire—especially dangerous in rain, snow, or mountainous areas. Imagine losing control and causing a crash; the consequences outweigh any temporary convenience. I’ve learned my lesson now—the moment I hear unusual noises or see warning lights, I stop and seek help immediately. Don’t cut corners in daily driving; the 4WD system is an integrated unit. Addressing issues promptly ensures peace of mind and safety.
The transfer case is the critical control point for a vehicle's four-wheel-drive function, and driving must not continue once it is damaged. It is responsible for evenly distributing power to the axles; if faulty, it may cause wheels to lose synchronization, leading to loss of vehicle control or rollover. Especially at high speeds, on slopes, or in slippery conditions, the risks multiply. It is strongly advised to immediately pull over to a safe location and contact professional rescue or towing services, avoiding any attempt to drive further.
