3. **Hydraulic Brake Fluid Test:** Measure moisture content in hydraulic brake fluid to avoid internal ABS module corrosion.
4. **Suspension Bushing Evaluation:** Check control arm rubber bushings for cracking to maintain steering alignment precision.
5. **Transmission Fluid Analysis:** Refresh automatic transmission fluid every 45,000 to 60,000 miles to preserve smooth gear engagements.
6. **All-Wheel-Drive Differential Service:** Drain and refresh rear differential and transfer case fluids to avoid clutch binding under load.
7. **Tire Tread & Rotation Audit:** Rotate tires every 5,000 miles to promote even tread wear and extend tire life.
8. **Electrical System Load Test:** Check battery voltage under load to maintain stable power for onboard electronics.
