2020 Jeep Wrangler
60,000 mile service checklist

Here's exactly what your factory maintenance schedule calls for at this mileage — and what each item typically costs.

60,000 mile service

  • Engine oil and filter change — 0W-20 full synthetic
  • Tire rotation
  • Replace cabin air filter
  • Replace engine air filter
  • Replace spark plugs — 3.6L Pentastar iridium (factory ~100k; replace at 60k if off-road use is heavy, plug fouling from low-speed crawling is common); 2.0L turbo: replace iridium plugs at 60k due to turbo combustion stress
  • Replace front axle gear oil — Dana 30/44: 75W-90 synthetic (on-road use) or 80W-140 synthetic (severe off-road/towing)
  • Replace rear axle gear oil — same spec; check for water contamination (milky appearance) from stream crossings
  • Replace transfer case fluid — ATF+4
  • Replace manual transmission fluid — GL-4 75W-90 (6-speed Tremec)
  • Replace automatic transmission fluid — ATF+4 (8-speed 850RE; some dealers do not recommend change but off-road use warrants it)
  • Replace brake fluid — DOT 3 or DOT 4
  • Inspect coolant — OAT (orange) extended life; first change typically 10 years/150k — inspect at 60k for pH and freeze-point
  • Inspect serpentine belt
  • Inspect all four wheel hubs and bearings (sealed on front; adjustable on some rear configurations)
  • Inspect front and rear differential cover seals
