Driveline and tire fitment
Lifting a Wrangler JK changes the driveline angles, and the driveshaft is the component most affected by a longer lift. Modifications help keep the joints working within range, and exhaust clearance on later models is a separate check that is often overlooked until the first hard articulation.
Tire size and wheel backspacing decide how much rub the new setup creates, so the wheel choice matters as much as the tire. Check the fender liners and steering components after the first drive, and look for rubbing at full lock. Lift components also benefit from a periodic check of bolts and bushings, because the added height puts more load on them.
- Check driveshaft U-joints for play
- Re-torque lift hardware after the first drives
- Inspect steering and track bar mounts for wear
