My jeep wrangler just passed 100,000 miles, what service does it need?
Here is the basic maintenance list for your Jeep:
~ Inspect lights and check tire pressure at least monthly or before & after each trail ride
~ Oil & filter change, chassis lubrication, differential and transfer-case fluids every 3,000 to 5,000 miles or 3 to 4 months - if you have recently crossed through water deep enough to submerge the centre of your hubs, replace the differential fluids as a precaution
~ Underhood belt and hose inspection every 3,000 to 5,000 miles or 3 to 4 months (every oil change)
~ Tire rotation and wheel balancing every 6,000 miles or every other oil change - driving offroad can knock wheel weights off a wheel, so you may need to have this done more frequently
~ Brake inspection every 6,000 miles or every other oil change - if you have rum brakes in the rear, ensure they are cleaned after each trail ride where you encountered deep mud/snow
~ Replace air filter every 12,000 to 24,000 miles or as indicated by inspection - dusty trails can shorten these intervals dramatically
~ Replace fuel filter every 24,000 to 100,000 miles
~ Automatic transmission service every 24,000 to 100,000 miles
~ Wheel alignment check every 12,000 to 24,000 miles or as indicated by tire wear - offroad driving can knock wheels out of alignment, so budget for an alignment every 3 months, then watch tread wear to see if it's needed
~ Cooling system flush and refill every 40,000 to 100,000 miles
~ Belt and hose replacement every 60,000 to 100,000 miles or 5 to 8 years
~ Engine timing belt replacement every 60,000 to 100,000 miles (when equipped) or 5 to 8 years
~ Air conditioning performance check annually, usually in the spring - be sure to run your A/C during the winter for brief period to ensure all hoses and valves stay lubricated and operable
