2020 Jeep Wrangler
90,000 mile service checklist
Here's exactly what your factory maintenance schedule calls for at this mileage — and what each item typically costs.
90,000 mile service
- Engine oil and filter change — 0W-20 full synthetic
- Tire rotation
- Replace spark plugs — 3.6L Pentastar iridium (if not replaced at 60k, replace now; second set for severe-use owners who replaced at 60k)
- Replace front and rear axle gear oil
- Replace transfer case fluid — ATF+4
- Replace brake fluid — DOT 3 full flush
- Inspect serpentine belt — replace if worn
- Inspect all coolant hoses
- Inspect steering linkage and ball joints — Wrangler off-road use accelerates ball joint wear significantly
- Inspect front swaybar disconnect (Rubicon electronic disconnect or manual linkage) for proper operation
- Inspect skid plates and underbody for impact damage from trail use
- Inspect shock absorbers for leaking or blown seals
