Since I moved from 33s to 35s my stock center link adjusting sleeve has been loosening up when off-roading. I decided to go with the Grand Cherokee center link as the upgrade; it's more beefy just like the tie rod upgrade. So for general information I thought I would post the AutoZone part numbers and prices. These are Duralast products.
Centerlink - DS1311. - $49.99
Tie Rod End - ES3096. - $34.89
Tie Rod Adjusting Sleeve - ES2079S. - $21.19

 

And if worse case you break it parts are easy to get today.
