SUBJECT:
Fluid Flushing Requirements
DISCUSSION:
Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include: engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only exception to this requirement are published in the vehicle maintenance schedules, e.g. engine coolant.
I would strongly recommend checking diff, gearbox and transfer case fluids if you go through any water while off-roading, even if it’s not that deep.
Had mine inspected as a precaution after doing some water fording (which the Jeep is supposedly rated for) and found water in gearbox and front diff.
