2022 Ram Chassis Cab maintenance schedule

The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.

A dot means the service is due at that mileage or after that many years, whichever comes first. Engines: ESB.

Additional Inspections
Inspect the CV/Universal joints.
Inspect front suspension, tie rod ends, and replace if necessary.
Inspect the front and rear axle surfaces. If gear oil leakage is suspected, check the fluid level. If using your vehicle for police, taxi, fleet, off-road or frequent trailer towing, change axle fluid.
Inspect the brake linings, parking brake function.
Additional Maintenance
Replace the cabin air filter.
Replace the engine air cleaner filter.
Replace spark plugs. The spark plug change interval is mileage-based only, yearly intervals do not apply.
Flush and replace the engine coolant at 10 years or 150,000 miles (240,000 km) whichever comes first.
Change the automatic transmission fluid (AS66RC Transmission Only).
Change the automatic transmission fluid and sump filter (AS66RC Transmission Only).
Inspect the transfer case fluid, change for any of the following: police, taxi, fleet, or frequent trailer towing.
Change the transfer case fluid.
Inspect and replace PCV valve if necessary.

At Every Oil Change Interval As Indicated By Oil Change Indicator System

  • Change oil and filter.
  • Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
  • Inspect engine cooling system protection and hoses.
  • Inspect exhaust system.
  • Inspect engine air cleaner filter if using in dusty or off-road conditions. Replace the engine air cleaner filter, if necessary.
  • Inspect battery and clean and tighten terminals as required.
  • Inspect the CV/Universal joints.
  • Inspect automatic transmission fluid if equipped with dipstick.
  • Inspect brake pads, shoes, rotors, drums, hoses and parking brake.
  • Inspect front end, and lubricate — If equipped with serviceable fittings.
  • Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty conditions.
