Ball joints connect your steering knuckle to your axle, allowing the knuckle to pivot so you can steer your Jeep. They can wear out over time, causing sloppy steering response or wandering when driving down the road. If you've installed oversized wheels and tires, that can wear out the original factory ball joints faster than usual.
You can replace you worn out ball joints with factory quality ball joints, or take the opportunity to upgrade them to heavier duty ball joints to help keep them from wearing out prematurely again. Installing new ball joints requires a special ball joint press to remove and install as they are pressed into the axle.
