Challenges That Your Vehicle Encounters When Its Transfer Case Goes Bad

Though a vehicle is seemingly fashioned from humongous components from the outside, there are several elements inside the car with separate functions that help in the overall functioning of the car.

The transfer case element is one of the significant automotive components that differentiate between an all-wheel-drive (AWD) and four-wheel drive (4WD) vehicles. Driving on all four wheels provides improved mileage and performance on bumpy and challenging roads. A smooth ride on rough terrain is only possible due to the transfer case, as it permits equal power transmission to both the front and rear wheels of the vehicle. When you encounter a faulty transfer case, you will find difficulty in switching to AWD or 4WD. Hence it is necessary to analyze the symptoms that can lead to component failure.

Multiple problems that the vehicle exhibits with a faulty transfer case:

The following problems can arise due to faulty or malfunctioning transfer cases.

1.   Difficulty in switching gears:

If you face problems changing your vehicle’s gears while driving, you may have a bad transfer case that restricts you from the gear switch. If the transfer has an adequate amount of fluid, the gear moves smoothly without causing any problem. But insufficient fluid can be due to leakage in the fluid container. Another fluid leakage condition arises when the pool of liquid is placed under the transfer case. If such a condition occurs, you need to call an industrial technician immediately. There are chances that your transfer case can completely collapse while driving.

2.   Unusual Noises:

The external shaft seal is not only used to maintain the fluid inside of your 4484 transfer case, but the seal also acts as a closure for the sound produced due to gear shifts. When the seal is dismantled or damaged, the sound through the seal escapes out, making an unfamiliar grinding noise that becomes hard to tolerate. With time the noise keeps on increasing when the transfer cases lose hydraulic fluid. The fluid acts as a lubricant, ensuring that all the parts in your moving vehicles are functioning correctly. Once the transmission fluid evaporates, the transfer cases end with no oil that is needed for lubrication. Further, the absence of oil between the transfer cases leads to metal-metal contact, making a more unusual sound than before.

3.   Inconsistent Four Wheel Drive Performance:

A four-wheel-drive system consists of three parts: part-time, full-time, and active. Part-time and active allows the transmission to function either on two wheels or four wheels. Under the part-time system, the driver changes the gear manually as and when needed. But the active drive allows a computer-based automatic gear shift from two-wheel to four when at suitable timing. Contrary to a part-time and functional form, total times operates on four-wheel-drive capacity every time. In other words, energy gets transmitted to both rear and axle parts every time you run a car. Leaks and further different damage are the sources of the flawed 4484 transfer case. Hence a regular check is necessary to avoid the inability of your transfer case.


Expert diagnosis is always recommended to avoid any confusion in your transfer case. You may encounter the challenges mentioned above when a transfer case problem arises. Examining your vehicle for several issues and repairing them will substantially increase the performance lately.
