REMOVAL & INSTALLATION STEERING COLUMN R & I CAUTION:When working on a collapsible steering column, DO NOT bump or hammer on column components. With column removed from mounts, it is extremely susceptible to impact damage. A slight impact on column end may collapse steering shaft or loosen plastic injections which maintain column rigidity. When removing steering wheel, use a proper puller. DO NOT hammer on puller to aid removal. On all models, always replace transmission linkage grommet when rod is disconnected. Removal Disconnect negative battery cable. On column shift models, disconnect transmission linkage rod from lever on steering column. Remove dust cover from steering shaft coupler at gear box. Remove shaft coupler clamp bolt. Remove floor plate mounting bolts. Remove instrument panel lower trim panel. Disconnect electrical connectors from steering column.
