Go to Carquest and buy an inner tie rod for your steering gear box. Part Number EV80782, $47. Put this in the back of your WK. You're most likely going to need one sooner or later.
At Grand Slam West 2007 I was driving Mopar Skunkworks' 05 CRD (euro spec) up the Moab Rim trail, this part broke (we had to call someone with a portable welder to fix the link).
Last year (2 years ago?) Will (fellow WKer) pretzeled one of his.
This month an attendee (Kevin) at GSW 2010 was wheeling after the event and...you guessed it, he bent one of his links. This is what it looks like:
Unfortunately for Kevin and Will, Chrysler doesn't know (or maybe care) that MOOG makes a replacement link, so the dealer's service departments put an entire new steering gearbox (complete with new links) into their WKs, costing waaaayyyy more than it should have.
Here's a pic that shows the stock part (bent) and the replacment MOOG part (the left and right links are interchangeable, so you only need one trail spare):
As you can see, the replacement has a flat spot you can use a wrench on, but the stock part is round, so you'll need something with teeth (pipe wrench or large vice grip) to remove the stock part. You'll also probably need a tie rod end puller. If you're intimidated with all this - don't wheel alone and make sure you have this part with you - a fellow Jeeper will probably be able to help you replace the link.
