Additional Inspections
Inspect the CV joints.
Inspect front suspension, boot seals, tie rod ends, and replace if necessary.
Inspect the brake linings, parking brake function.
Inspect front accessory drive belt, tensioner, idler pulley, and replace if necessary.
Additional Maintenance
Replace engine air cleaner filter.
Replace air conditioning/cabin air filter.
Change brake fluid every two years.
Replace spark plugs.
Flush and replace the engine coolant at 10 years or 150,000 miles (240,000 km) whichever comes first.
