It is easy to install a lift and forget about it but these things really needed to be checked over once an a while and every thing re-torqued. I like to go over mine every 5000 miles or so or after a good hard week of wheeling. I just got back from Moab where I spent a lot of time bouncing around on the trails and yesterday crawled under the rig with my torq wrench. Most everything was still good and tight but both front upper control arms needed a 1/2-3/4 turn to click on the set torque and the passenger rear upper control arm was even looser. I am a firm believer that the paint pencil marks are not a good indicator, as going by that they should have been fully torqued. I find it somewhat common that the front and rear track bar need re-torquing every once and a while and when I have buddies who are complaining of their jeeps wondering on the road that is the first thing I check and more often than not I find they are not close to 120-125 ft/lbs.
