Transfer Case Failure Signs & Maintenance Tips
Transfer Cases Signs of Failure & Maintenance Tips
Found in all-wheel drive (AWD) and four-wheel drive vehicles (4WD) (and is sometimes found in off-road vehicles), this drivetrain component sends torque to the front and back wheels and receives power from the transmission's output shaft.
The transfer case controls power and torque distribution between the vehicle's axles rather than only to the front or rear wheels.
AWD vehicles have the simplest transfer cases, while vehicles with different drive modes have more complex transfer cases.
There are two main types of transfer cases:
4WD - enables the automobile to transition between two- and four-wheel drive modes by transferring power to the front and rear wheels.
AWD - made to deliver power to all four wheels at once. It is, therefore, perfect for our slick and snowy Midwestern winter roads.
The transfer case distributes power to the front and rear wheels. If it's not functioning properly, imbalances in power distribution can occur, affecting the vehicle's handling and traction, especially in challenging driving conditions like off-road or slippery surfaces.
7 Reasons for Failure
Uneven tire pressure or fluid levels: Insufficient fluid or pressure in the transfer case can lead to several problems, including damage. Maintaining the correct tire pressure and fluid levels for them to continue operating properly is crucial.
Not installed correctly: Improper installation can impact the drive train and transmission, among other vehicle components - you can avoid the headache by getting a qualified technician to do the work.
Natural deterioration (wear & tear): The mechanical parts of a car's transfer case (such as the seals, bearings, and gaskets) have a limited lifespan and need to be replaced, which is one of many solid arguments for investing in routine maintenance.
Unintentional damage: If your vehicle has experienced sudden impact (such as an auto accident), your transfer case could be affected and require repair.
Overheating: Many situations can cause overheating, which can cause your transfer case (and its components) to fail.
Rust and corrosion: If your vehicle's transfer case sustains significant damage from rust and corrosion, it may not transfer power effectively.
How Can You Tell Your Transfer Case Is Failing?
Difficulty Shifting Gears: In vehicles with 4WD capabilities, a faulty transfer case can make it difficult to shift between 2WD and 4WD modes. This is particularly problematic when engaging or disengaging 4WD in off-road or adverse weather conditions.
Vehicle Stalling or Failure to Move: In severe cases, a damaged or broken transfer case can cause the vehicle to stall or not move at all, as the power cannot be effectively transmitted to the wheels.
Abnormal Sounds: Transfer case noise indicates potential mechanical issues and should be looked at by a mechanic immediately. Grinding sounds, whirring, or humming can indicate internal damage or inadequate lubrication in the transfer case.
Your Warning Lights Come On: When warning lights come on, it's (literally) a blaring indication that there's trouble in vehicle paradise. You and your automobile will be safer if you get your vehicle in to see a technician immediately. Another perk is that quicker action generally means less expensive repairs.
Leaks Fluid: Fluid under a transfer case indicates a leak in the transfer case itself. This leak should be repaired as soon as possible because of the potential for a drop in fluid pressure.
A Tip from The Pros: The signs of a bad transmission can look like those of a bad transfer case. A qualified technician can diagnose the root of your vehicle's issue and guide you appropriately. Don't wait to find out the hard way that you're dealing with an expensive and potentially unsafe problem.
Transfer Case Maintenance
Maintaining a transfer case is a straightforward process, as both typical cars and pickup trucks exhibit noticeable signs when repairs become necessary. Despite variations in hardware among different automotive brands, common issues arise when specific components are damaged or defective. Regular maintenance is crucial for vehicle ownership, and here are some tips:
Regularly check the fluid levels in the transfer case. Change the fluid in the differentials and transfer case as recommended by the manufacturer. The recommended interval for changing the fluid can be every 30,000 to 36,000 miles. In some cases, you may need to change it every 15,000 miles.
Inspect for any leaks or damage when examining the vehicle from underneath.
Over time, transfer case parts will naturally wear out, requiring repairs. However, consistent and proper servicing of your transfer case will help delay this inevitability as much as possible.
Money Talk: What To Expect from A Repair or Replacement
Before you agree to repair or replace your transfer case, discuss the cost with your technician to avoid sticker shock.
That said, a transfer case is one of the priciest parts in a vehicle, so anticipate a significant cost. Because it plays a key role in your vehicle's operation, acting quickly and making repairs as needed is critical. The longer you let it slide, the more costly the problem's likely to get.
The final answer to "What will this cost me?" is "It depends!".
The cost of replacing or repairing a transfer case can vary depending on factors like the extent of the repair and the vehicle's brand and model. Likely, it will fall between $2,500 and $3,500. Still, it's vital to obtain a precise quote from a skilled technician first.
