Four Wheel Drive

Navigating the Unknown: Exploring Your Vehicle's Four-Wheel Drive System

Four-wheel drive (4WD) systems are popular in off-road vehicles, 4x4 trucks, and SUVs. This type of drivetrain configuration simultaneously delivers power to all four of your vehicle's wheels, providing superior all-terrain handling and mud and snow traction. Understanding how the 4WD system works and knowing the signs that something’s wrong are essential in recognizing when it's time to get your vehicle serviced by the 4WD experts at Brakes Tires & More.

Four-Wheel Drive Setup

4WD systems comprise several components. However, when even one fails, your vehicle can become unsafe to drive. It's critical to recognize when there is trouble so you can take your vehicle to Brakes Tires & More for service. 

Power Distribution

4WD systems deliver equal power to all four wheels, ensuring that each one receives the necessary torque to maintain traction and avoid slippage. A transfer case, a gearbox that splits the power between the front and rear axles, facilitates this distribution 

Transfer Case 

The transfer case allocates power to the front and rear differentials. It allows the driver to engage and disengage the 4WD system and provides improved off-roading performance. The transfer case controls the differential locks to maintain traction in challenging environments.

Engaging and Disengaging 4WD

To engage or disengage the 4WD system, drivers must use a control switch or lever. This switch or lever activates the transfer case, which sends power to the front and rear axles and engages the differential locks. Reversing the process disengages the 4WD system.

Differential Locks

Differential locks provide additional traction and improve off-roading performance. They lock the front and rear differentials together, ensuring that both wheels on each axle turn at the same speed.

All-Wheel Drive (AWD) vs. 4WD

While all-wheel drive (AWD) and 4WD systems both provide improved traction and handling, they function differently. AWD systems are typically found in passenger vehicles and crossover SUVs and supply power to all four wheels at all times. 4WD systems are usually found in off-road vehicles, 4x4 trucks, and SUVs and deliver power to all four wheels only when necessary, such as in rugged terrain.

Signs You Need Your 4WD Serviced

Watch for signs that your 4WD system needs to be serviced to ensure superb performance and safety. Regular maintenance guarantees prime operation and keeps your passengers safe.

Trouble Shifting Gears

If your vehicle is having trouble shifting gears, it could be a sign that your 4WD system needs diagnostic and repair services by Brakes Tires & More. Worn-out gears, a malfunctioning shift motor, or a faulty transfer case could cause this issue. 

Odd Noises

If you hear any unusual noises coming from your vehicle while driving, a professional at Brakes Tires & More should check it out. Loose bolts, rundown gears, or a damaged transfer case can cause these noises. 

Difficulty Staying in 4WD

If your vehicle has difficulty staying in 4WD mode, there could be an issue with the transfer case or the shift motor. Slipping out of 4WD mode unexpectedly can be dangerous. It's important to bring your vehicle to Brakes Tires & More so professionals can assess and fix the issue. 

4WD Won't Engage or Disengage

If you experience difficulty engaging or disengaging 4WD, get it checked out immediately by the specialists at Brakes Tires & More. This can be caused by a malfunctioning shift motor, an impaired transfer case, or a compromised drive shaft.

Warning Dashboard Lights

Warning lights could indicate an issue with your vehicle's 4WD system. Bring your vehicle into Brakes Tires & More for inspection.

Fluid Leaks Under the Transfer Case

Fluid leaks under your vehicle's transfer case could be a sign of a problem with your 4WD system. Cracked housing, a damaged transfer case, or overly worn seals could be the root of this problem. The experts at Brakes Tires & More can diagnose and remedy the issue.

4WD System Inspection

Regular inspection of the 4WD system by Brakes Tires & More is essential for optimal vehicle performance. This includes checking the transfer case fluid and performing any differential service. Regular maintenance is vital to keep all components of the 4WD system in top working order, including the front and rear differentials.
