Apparently, giving some love to the shifter knobs angered the Jeep gods, and soon thereafter, the T-case linkage blew up—at both ends. We’ve all heard the horror stories of these things dying due to some dumb $3 plastic clip. Frankly, I don’t have the time to take the Jeep apart once a year to replace some clip after getting stranded, because I can’t shift into 4WD. So, I turned to Advance Adapters for its heavy-duty cable linkage (PN 715596). The installation turned out to be a bit more involved than I planned, but in 30,000 miles, I haven’t had a single issue out of it yet.
