[Andy C]

I have a 2003 Jeep liberty that has just hit 60k. What is critical to get done on that mileage?

[Wayne W]

According to the owner's manual, these things should be done:
-Change the engine oil and engine oil filter.
-Inspect the engine air filter element, replace if necessary.
-Replace the spark plugs.
-Inspect and replace the PCV valve, if necessary.L
-Replace the ignition cables (2.4L Only).
-Inspect the brake linings.
-Drain and refill the front and rear axle fluid.
-Drain and refill the automatic transmission fluid, and replace main sump filter.
-Inspect the drive belt and replace as needed.
-Drain and refill the transfer case fluid.

Add coolant flush to the list.

Additional recommended services:
Clean fuel injectors.
Clean throttle.

What is critical though? Nothing but the oil change really. It is all "recommended" maintenance.
