Worried About Your Transfer Case? We Can Help.
If you’re hearing clunking sounds, experiencing trouble shifting into 4WD, or seeing drivetrain warning lights, don’t ignore it. Catching transfer case issues early can save you thousands in future repairs.
What Causes a Transfer Case to Fail?
Your vehicle’s transfer case plays a crucial role in the drivetrain, especially in 4WD and AWD systems. It’s responsible for distributing power from the transmission to the front and rear axles, helping you maintain traction and control on slick Wisconsin roads. But like any hardworking component, the transfer case can wear down or fail—especially without proper care.
At Joe’s Slinger Service, we’ve seen our fair share of transfer case issues in vehicles around Washington County, and the surrounding areas. Here are the most common reasons transfer cases fail:
1. Low or Dirty Transfer Case Fluid
Over time, transfer case fluid breaks down or leaks out. If it gets too low—or becomes contaminated—it can’t protect internal gears from heat and friction. The result? Premature wear, grinding noises, and eventually, total failure.
2. Lack of Maintenance
Many drivers forget about the transfer case during regular service. Skipping fluid changes or ignoring recommended service intervals allows wear and debris to accumulate, damaging seals and components.
3. Heavy Towing or Off-Roading
Using your truck or SUV for heavy towing, plowing, or rough terrain without properly engaging 4WD (or doing so improperly) puts extra strain on the transfer case and can cause serious internal damage.
4. Worn Internal Gears or Chains
With time and use, internal parts like gears and chains simply wear out. High mileage, poor fluid condition, or tough driving conditions will accelerate this process.
5. Electrical Failures (In Electronic Transfer Cases)
Modern 4WD systems often rely on electronic shift motors and sensors. When those components fail, your vehicle may not shift into or out of 4WD properly—even though the transfer case itself may still be functional.
6. Mismatched or Uneven Tire Wear
Running different tire sizes (or even significantly uneven tread depth) on AWD or 4WD systems can lead to drivetrain binding. That extra stress can wear out your transfer case much faster.
7. Improper Use of 4WD
Engaging 4WD on dry pavement in a part-time system causes excessive binding between the wheels and can quickly damage the transfer case. Always follow your owner’s manual instructions.
