Steering Wheel Off-Center and Binding After Column Repair
A tilt/telescoping steering column was removed to replace a worn upper bearing and the ignition switch. After reassembly, the steering wheel sits about 30° off center when the wheels are straight, the wheel binds when tilted to the lowest position, and the horn does not work. The technician plans to pull the steering wheel and re-index it on the shaft splines to center it. The intermediate shaft was reconnected with the pinch bolt tightened. The column was not marked before disassembly.
1. Evaluate the plan to re-index the steering wheel to correct the off-center condition and explain the correct approach.

Re-indexing the wheel on the shaft is the wrong fix and can cause problems: the wheel-to-shaft splines are keyed/indexed, and the correct centering is achieved at the intermediate shaft-to-gear or column coupling, not by rotating the wheel on its splines. If the wheel is moved on the shaft, the turn signal cancel cam and clock spring can be misindexed, which also explains the horn failure. Correct approach: with the front wheels straight ahead and the gear at center, disconnect the intermediate shaft at the column or gear coupling, rotate the column/wheel to center, and reconnect so the wheel is centered with the gear at its high point. Then verify the clock spring is centered per procedure and the cancel cam operates correctly.
2. The wheel binds only at the lowest tilt position and the horn is dead. Give the likely causes and the checks to confirm them.

Binding at full tilt-down suggests the column shroud, wiring, or clock spring is being pinched, or the tilt mechanism/lock shoe is misassembled or over-tightened, or the intermediate shaft joint is binding at that angle. The dead horn points to the clock spring/horn contact ring being misindexed, damaged, or unplugged during the bearing/switch replacement. Checks: 1) Inspect the clock spring for centering and continuity to the horn circuit; 2) Look for pinched harness or shroud contact through the tilt range; 3) Operate the tilt through its full range and watch for interference and listen for the bind location; 4) Verify the tilt lock and shoe assembly per the service procedure; 5) Confirm the horn relay and ground. Repair the interference and replace/recenter the clock spring, then recheck horn and tilt through full travel.
