Ford Bronco maintenance schedule
The Ford Bronco maintenance schedule follows the Intelligent Oil-Life Monitor for oil, with a limit of one year or 10,000 miles. The 2022 manual adds fixed items: brake fluid every 3 years, cabin air filter every 20,000 miles, engine air filter every 30,000, spark plugs at 100,000, coolant first at 10 years or 200,000 miles, and transmission, axle, and transfer case fluids at 150,000 miles under normal use.

The reminder system
The oil-life monitor counts how the engine is used and asks for an oil change when the oil wears out, not at a set mileage. Low-range crawling, idling, and towing use up oil life faster. Ford still caps it at a year or 10,000 miles. The Ford maintenance schedule page explains the messages and the reset.

Off-road and other severe use
The 150,000-mile fluid intervals are for normal driving. Ford’s 2022 Bronco manual adds a list for special operating conditions, and it applies when you drive that way most of the time, not now and then:
| Condition | Extra maintenance |
|---|---|
| Off-road operation | Oil and filter every 5,000 miles or 6 months; inspect steering linkage, ball joints, and U-joints often; replace the engine air filter as needed |
| Hard off-road use in heat (long sand, dune, or desert runs in 4WD above 90°F) | Front axle and transfer case fluid every 30,000 miles or 2 years |
| Dusty or sandy roads | Oil and filter every 5,000 miles or 6 months; tire rotation every 5,000 miles |
| Towing or a roof carrier | Spark plugs every 60,000 miles; inspect U-joints often |
| Long idling or low-speed driving | Spark plugs every 60,000 miles |
Summary of Ford’s list. Read the full section of your manual for your year.
Ford also says the axles and transfer case need a fluid check or change if a leak is suspected or the assembly has been submerged in water, so book one after a deep water crossing. See differential fluid and normal vs severe maintenance.
Manual or automatic
The 2.3L Bronco is offered with a 7-speed manual as well as the 10-speed automatic. Ford’s 2022 schedule lists the manual transmission fluid at 150,000 miles, the same as the automatic transmission fluid and filter, under normal use.
FAQ
How often does a Bronco need service?
When the oil-life monitor asks, or once a year or every 10,000 miles, whichever comes first. Filters, plugs, and fluids follow fixed intervals in the manual.
When should I change Bronco differential fluid?
Ford’s 2022 manual lists 150,000 miles for normal use and every 30,000 miles or 2 years for the front axle after long, hot off-road runs in 4WD. Have it checked after the axle has been under water.
Does the Bronco need brake fluid changes?
Yes, every 3 years in the 2022 manual, whatever the mileage. See brake fluid flush.
