If you own a Jeep Wrangler TJ and happen to run larger tires (most of us do) or off-road it at all, you're likely going to go through ball joints in short order. Depending on how hard you wheel (and how big your tires are), it's not uncommon to have to replace them every 40k miles (sometimes less). That being said, if you plan on keeping your TJ for a long time, it will save you time and money to learn how to change your own ball joints. This isn't that difficult of a job as long as you have some time and the special tools.
NOTE: This article applies to both the Dana 30 and Dana 44 front axles on the Jeep Wrangler TJ, as well as the Jeep Cherokee XJ.
Parts
I'd probably start by reading this thread: Which ball joints are the best for my Jeep Wrangler TJ.
In summary however, the ball joints you will want to get are the Dana / Spicer 706944X Suspension Ball Joint.
That kit includes all the parts you'll need to replace your factory ball joints with the best possible ball joint out there, hands down.
Special Tools
I highly, highly suggest purchasing these tools when doing your ball joints. These tools will make the job so much easier (not an exaggeration either)!
You'll also need other basic tools such as a full socket set (preferably metric and SAE), different size ratchets, socket adapters, a torque wrench, etc. In other words, don't attempt this unless you have a decent set of tools.
Procedure
I'm not going to sit here and type it all out. I can do you one better! Check out this very informative video that will show you step-by-step how to change out your ball joints.
Last but not least, after you're done doing all of this, make certain to reset your toe-in!
