Jeep Wrangler Maintenance: a Guide to Keeping Your Jeep in Good Shape

Jeep Wrangler Maintenance

The Jeep Wrangler has been a popular off-roading SUV since 1941. With many updates that include a smooth drive on the road, it’s become a fan favorite among adventurers and commuters alike.


Auto maintenance is vital to any car’s longevity, especially one that is used off-road.

When regular jeep wrangler maintenance is overlooked, issues can build-up, resulting in expensive and complication solutions that’s why maintaining your new or used jeep wrangler can extend its life and keep it running for years to come.

Dos and Don’ts of Regular Maintenance

Every vehicle should have regularly scheduled maintenance. Here are a few common maintenance items to keep in working order:

Tire Pressure and Rotation

Periodically checking a car’s tire pressure can help reduce wear and maximize gas mileage. You can find the ideal tire pressure for your car in the owner’s manual.

You can find the recommended tire pressure on a sticker inside the driver’s door. In addition to maintaining proper tire pressure, tires need to be rotated every so often.

The timeframe between tire rotations varies on the car and its use. Off-roading vehicles, such as Jeeps may have more wear and tear than a car used only for commuting to a workplace.

Many manufacturers recommend that tires be rotated in the same appointment as an oil change. This is typically every 7,500 miles or six months.

Oil Change

A car’s oil is a large part of what makes the engine run. The engine relies on oil to run, cool, and lubricate its parts. Regular oil changes help keep the oil clean and prevent engine damage. Drivers can check their cars oil level under the hood of the vehicle.

Brake Inspection

It’s important to have brakes inspection to reduce risk of failure and accidents. It’s recommended to have brakes inspected during tire rotations or if they are making an unusual noise such as squeaking or grinding.

Jeep Wrangler Specific Maintenance

To keep costs down, it’s important for Jeep Wrangler owners to keep up to date with maintenance. The Jeep Wrangler has a reliability rating of 3.5/5 according to RepairPal.

It ranks 25th out of 26 for compact SUVs, based on average cost and frequency and severity of maintenance and repairs. The average repair cost for a Jeep Wrangler is $694, which is an average owner costs compared to other vehicles.

Rotate and Check Tires

Maintaining tires is especially important in an off-roading vehicle due to different terrain. It’s recommended that a Jeep’s tires are rotated and balanced every 6,000-8,000 miles and wheel alignment is checked every 20,000 miles.

Off-roading can misalign tires easily, so be sure to have wheels aligned every three months or so.

Check and Change Oil (and Other Fluids)

A Jeep Wrangler’s oil can be changed by a professional or by the owner. Jeeps typically sit high, so getting underneath doesn’t require a jack.

Other fluids to check are power steering, transmission, and radiator fluid. The ideal levels can be found in the Jeeps owner’s manual. If you are off-road with your Jeep in water higher than your tires, you should change the fluids after every high water encounter to avoid any potential issues.

Brake Pad Replacement

Brake pads can wear down over time and if not maintained, can cause braking issues. In addition to regularly scheduled braking system maintenance, brake pads should be changes between 25,000 and 60,000 miles.

Additional Jeep Maintenance items include:

  • Air filter replacement
  • Tire pressure inspection before and after off-roading
  • Tire condition before and after off-roading
  • Drum brake inspection

Maintaining a Used Jeep Wrangler

When purchasing a used Jeep (or any car), it’s important to know its maintenance history, especially since maintenance schedules varies from vehicle to vehicle.

It’s imperative to have a trusted mechanic, auto shop, or dealership who can advise you on best maintenance practices for your used Jeep Wrangler.

One major part to pay attention to is the axles and suspension. If these are checked every inspection and oil change, small issues can be dealt with before they escalate into bigger (and more expensive) problems.
