What are the symptoms of a faulty transfer case?

If a vehicle's transfer case is damaged, it will be unable to switch to four-wheel drive mode, and may even prevent the car from driving normally. Only four-wheel drive vehicles have a transfer case, which is a crucial component for such vehicles. The transfer case is a device that distributes the engine's power, directing it to either the rear axle or both the front and rear axles simultaneously. Here is some relevant information about transfer cases: 1. Part-time four-wheel drive vehicles can operate as two-wheel drive under normal conditions but switch to four-wheel drive for off-road situations. The transfer case in part-time four-wheel drive systems is a purely mechanical device. 2. When engaged in four-wheel drive mode, this type of transfer case rigidly connects the front and rear axles, enabling a 50:50 power distribution between them, which significantly improves the vehicle's off-road capability. 3. Additionally, due to its purely mechanical construction, it offers high reliability, which is vital for vehicles frequently driven in remote wilderness areas where rescue services are scarce. 4. Even today, many rugged off-road vehicles still use this type of transfer case.
I've been driving for many years, especially on off-road sections, and there are several obvious signs when the transfer case is failing. The car vibrates heavily, and the steering wheel shakes, particularly when turning or going uphill. You'll hear rattling noises, like gears grinding, especially noticeable at low speeds. Oil leakage is another indicator; you can see oil stains under the car after parking. When shifting into 4WD mode, it might get stuck or not respond, and the 4WD warning light on the dashboard will illuminate. This affects the entire drivetrain, causing uneven power distribution, accelerated tire wear, and increased risk of skidding or losing control on slippery roads. As an experienced driver, I believe it's crucial to get it checked at a professional shop promptly, before minor issues turn into major problems.
My four-wheel-drive vehicle has been experiencing this issue recently, with symptoms including severe vibrations while driving, to the point where the steering wheel shakes uncontrollably when starting from traffic lights in the city. There's also a noticeable humming noise, seemingly coming from underneath the vehicle, which becomes louder during acceleration or turning. After parking, I found oil stains on the garage floor, specifically in the transfer case area. The four-wheel-drive system warning light on the dashboard has also illuminated, and switching modes is unresponsive at times or completely fails. This might lead to increased fuel consumption or lack of power when climbing hills. It's advisable to check the oil level but avoid attempting repairs yourself to prevent further damage, as safe driving is paramount.
