Tire Rotation Procedure
- Check vehicle's recommended rotation pattern (typically forward-cross or X-pattern)
- Loosen lug nuts on all wheels before lifting vehicle
- Safely raise and support vehicle on appropriate lift points
- Remove wheels and inspect brake components while accessible
- Clean wheel mounting surfaces and hub faces
- Rotate tires according to recommended pattern
- Reinstall wheels with proper torque sequence (star pattern)
- Torque lug nuts to specification using calibrated torque wrench
- Lower vehicle and recheck torque after wheel rotation
Brake System Inspection
- Remove wheels for full access to brake components
- Measure brake pad thickness at thinnest point (replace if below 4mm)
- Inspect brake rotors for scoring, warping, or cracks
- Measure rotor thickness and compare to specifications
- Check calipers for smooth operation and piston movement
- Inspect brake hoses for cracks, leaks, or damage
- Verify proper brake fluid level and condition
- Test brake pedal feel and travel
- Document all measurements for future reference
Fluid Inspection & Service
- Check engine oil level and condition before draining
- Drain oil completely from warm engine
- Replace oil filter and gasket
- Add manufacturer-specified oil type and quantity
- Check transmission fluid level and condition with vehicle running
- Inspect coolant level, color, and freeze protection
- Check power steering fluid clarity and level
- Verify brake fluid level and condition
- Top off windshield washer fluid
Battery & Electrical System Check
- Clean battery terminals and cable ends
- Check battery voltage (should be 12.6V or higher when fully charged)
- Perform load test to verify battery condition
- Check charging voltage (13.8-14.8V at idle)
- Inspect alternator belt for tension and condition
- Test all exterior lights for proper operation
- Verify horn and wipers function correctly
- Scan vehicle for diagnostic trouble codes
- Test starter current draw if starting is sluggish
