I just went through this with my Maverick. Put it up on jackstands, measure the distance from the inner edge of a tire to the frame rail at full lock one way, then compare that to the same measurement on the other side at opposite lock. Now adjust the rod-ends so those distances are the same while watching how many threads are showing on each rod-end, they should be close to equal. You will also have to take your toe-in into account. I found it easier to disregard the toe and center the wheels first, then adjust the toe-in by making equal moves on both rod-ends until it was right.
