Whether it’s a full-time AWD BMW, a selectable 4WD truck, or an electronically controlled SUV, every system requires routine inspection. Our technicians check for leaks, worn seals, binding, and improper engagement.

We use OEM-level scan tools and live data testing to verify actuator performance, clutch pack operation, and fluid temperature regulation — ensuring your system functions as intended in every mode.

The transfer case and differentials distribute torque between your wheels — but without clean fluid, internal wear can happen fast. We perform fluid exchanges using manufacturer-specific lubricants, replacing any necessary gaskets or crush washers to prevent leaks.

Our services include:

• Front and rear differential fluid replacement
• Transfer case fluid service
• Inspection of vent tubes, seals, and output shafts
• Verification of fluid level and condition
• Replacements

Proper lubrication means quieter operation, smoother shifts, and extended component life.

Your 4WD system depends on more than just gears. Driveshafts, U-joints, CV axles, and hubs all play a role in smooth power delivery. We inspect and service these components to prevent vibration, binding, and uneven tire wear.

We also evaluate wheel speed sensors and control modules, making sure your traction and stability systems work seamlessly with your drivetrain — because modern 4WD performance is about control, not just power.

If your 4WD system hesitates to engage, makes noise, or hasn’t had fresh fluid in years, now’s the time. Schedule four-wheel drive service with The Garage MKG today. Call (231) 246-7735, visit us at 1860 Henry St, Muskegon, MI, or book online anytime.
