Cars with four-wheel drive (4WD) and all-wheel drive (AWD) need a transfer case to operate, but when it fails, serious mechanical problems can happen. Below, we discuss the main signs of a problematic transfer case. When your car needs transmission service in Greensboro, NC, or the surrounding areas, contact Continental Motors to get the job done.
What Is a Transfer Case?
A transfer case is a gearbox found in 4WD or AWD vehicles that distributes power to the front and rear axles from the transmission. It facilitates the transition between multiple driving modes, including 2WD, 4WD high, and 4WD low, depending on the terrain and vehicle. If the transfer case isn't functioning properly, your car won't be able to engage 4WD or handle challenging driving conditions like snow or off-road terrain.
How Does the Transfer Case Affect the Transmission?
The transmission and transfer case efficiently transmits power to the wheels. A broken transfer case can overtax the transmission and result in problems like poor wheel power or gear slippage. The transmission and transfer case must work together for your car to function properly.
Signs of a Bad Transfer Case
Strange Noises
Grinding, clunking, or whining noises when changing into 4WD or AWD are the first signs of a failing transfer case. These sounds could be a sign of faulty gears or worn bearings inside the case.
Difficulty Shifting Gears
Unexpected 4WD disengagement or issues with AWD or 4WD engagement may be signs of issues with the transfer case. Slow or rough shifting between gears may be a sign of internal deterioration.
Leaking Fluid
Specialized fluid is used to lube the internal gears of transfer cases. Overheating and mechanical failure may result from a fluid leak that reduces lubrication. As soon as you see fluid under your vehicle, get it checked.
4WD or AWD Won’t Engage
A defective transfer case may completely prevent the car from switching to 4WD or AWD modes. If your vehicle struggles to move between these modes, especially when driving unevenly, the transfer case could need to be replaced or repaired.
Warning Lights
Some vehicles have 4WD or AWD warning lights on the dashboard. If this light comes on, there could be a sensor issue with the transfer case.
