"For as long as there have been Jeeps they have wandered down the road. Wandering along...
If you have driven a Jeep, you know the feeling. The steering wheel goes two inches to the right, two inches to the left and then back again, while your vehicle stays in a relatively straight line. That is the result of your Tie Rod rolling forward and backward forward and backward again and again. That's simply because there is nothing there to prevent it from doing that. And early wear on tie rods simply because they are always in motion. This results in torn tie rod boots because they have been flexed a jillion times in.
The Cure:
Used against only the face of our Y-Link Adapter or a common Y-Link Tie Rod. It gives a self lubricated, fixed yet slightly flexible surface for the tie rod to rest against. The drag link does not flop forward or backward whatsoever yet in common usage it is allowed to roll which causes the steering wheel dead spot and allows for the tie rod roll."
