Four Wheel Drive
Rough Roads? No Problem! 4WD Service Done Right!
From slippery roads and muddy forest trails to rocky desert terrain and water-logged crossings, your four-wheel drive takes you places ordinary vehicles fear to tread. But the very features that power its extraordinary off-roading performance are the same reason it demands more care than an average vehicle.
This is precisely why Baldwin's Tire and Alignment has been perfecting the art of 4WD servicing since 2023. We understand that when your wheels work four times as hard, they need four times the expertise.

Understanding 4WD Systems: It’s Not Magic — It’s Mechanics
A 4WD drivetrain system simultaneously sends power to all four wheels. Behind this simplified explanation lies a finely tuned ensemble of complementary components that power your beastly ride through rough terrains. Notable components include:
Transfer Case
The transfer case is the heart of every 4WD transmission system. True to its name, it transfers power to both the front and rear axles, enabling your 4WD vehicle to tackle whatever terrain.
Depending on your vehicle’s model, this case may feature adjustable modes that optimize power distribution to match your driving conditions. Some models have a 4-high mode for increased traction on slippery surfaces and a 4-low mode for maximum torque during off-road driving.
Baldwin's Tire and Alignment expert mechanics are thoroughly trained in all configurations to ensure they can offer the 4WD servicing your ride needs regardless of transfer case design.
Differential Locks
Advanced four-wheel drive systems feature front and rear differential locks. These prevent wheels on the same axle from spinning at different speeds. This ensures power is evenly distributed through your 4x4 drivetrain, enabling your vehicle to conquer even the most extreme off-road conditions.
All-Wheel Drive vs. 4WD
While often used interchangeably, all-wheel drive (AWD) and four-wheel drive systems differ. AWD drivetrains are incorporated in rides meant for on-road use. They transmit engine power to all four wheels simultaneously but variably.
4WD systems lock the front and rear differentials together, forcing all four wheels to rotate at the same speed. This is what makes 4x4 trucks and SUVs with 4WD so good at off-road adventures.
In most vehicles with 4WD, the driver can engage or disengage the system using a selector switch or lever. Baldwin's Tire and Alignment expert team is well-versed in AWD and four-wheel drive options. We will accurately diagnose and service your vehicle regardless of its drivetrain configuration.
