Helllo .. thanks for the donation .. much appreciated

Hope this helps .. let me know

STEERING COLUMN (EXCEPT W BODY)
CAUTION:Columns must be handled with care when removed from vehicle. Use only fasteners of the same or equivalent part number if replacement is necessary. Improper fasteners or tightening could result in failure. Applying excessive pressure, or causing impact to mainshaft during service, may cause the column to collapse.

Removal
Disconnect and shield negative battery cable. Ensure front wheels are in straight ahead position. On vehicles with SIR, remove SIR fuse from fuse block. Disconnect the Connector Position Assurance (CPA) and Yellow 2-way SIR harness connector at base of steering column.
Turn ignition switch to LOCK position before disconnecting steering column or intermediate shaft from steering gear.
NOTE:Failure to lock steering shaft may cause coil assembly to become uncentered, which will cause damage to coil assembly.

On all models, remove steering wheel if steering column is being repaired or replaced. See STEERING WHEEL under REMOVAL & INSTALLATION. Remove stop light switch. Remove joint coupling bolt and nut attaching upper intermediate shaft to steering column. On column shift models, disconnect transmission linkage rod from lever on steering column.
Remove steering column lower trim panel. Remove knee bolster and deflector at base of steering column. Remove toe plate-to-cowl attaching bolts. Remove shift cable from steering column. Unplug electrical connectors from steering column. Remove steering column bracket mounting nuts. Remove steering column.
Installation
To install, reverse removal procedure. Tighten bracket mounting nuts to 20 ft. lbs. (27 N.m). Tighten joint coupling nut to 40 ft. lbs. (54 N.m). On vehicles with SIR, connect SIR system. Check AIR BAG light for system faults. See AIR BAG SYSTEM under SAFETY PRECAUTIONS.
STEERING COLUMN (W BODY)
Removal & Installation
Disconnect and shield negative battery cable. Remove left side sound insulator and trim panel below steering column. With steering column unlocked, push top of intermediate shaft seal down for access to upper intermediate shaft coupling and upper coupling bolt.
Remove upper coupling bolt. Remove shift indicator cable end and casing from steering column (park interlock cable if floor shift). Remove upper and lower steering column bolts and lower steering column to seat. Disconnect electrical connectors. Separate upper intermediate shaft from lower steering shaft and remove steering column. To install, reverse removal procedure. Tighten coupling bolt to 35 ft. lbs. (47 N.m). Check for proper operation.

STEERING WHEEL
CAUTION:DO NOT strike steering shaft with hammer to remove steering wheel. Hammering could loosen the plastic injections which maintain column rigidity. On vehicles with SIR, DO NOT thread puller bolts all the way through steering wheel hub. Threading puller bolts too far through steering wheel may cause damage to coil assembly.

Removal & Installation
Disconnect and shield negative battery cable. Remove horn pad by pulling up. Turn ignition switch to ON position. On vehicles with SIR, ensure front wheels are in straight-ahead position. Turn ignition switch to LOCK position. Remove SIR fuse from fuse block. Disconnect the Connector Position Assurance (CPA) and Yellow 2-way SIR harness connector at base of steering column.
On vehicles with SIR, remove air bag module retaining screws from rear of steering wheel. Pull module away from steering wheel and disconnect coil assembly connector from module. Disconnect horn wire from steering column and remove module.
On all models, scribe an alignment mark on steering wheel hub in line with steering wheel shaft. Remove steering wheel nut. Using appropriate steering wheel puller, remove steering wheel. To install, reverse removal procedure. Align scribe marks on steering wheel hub and steering wheel shaft. Tighten steering wheel nut to 30 ft. lbs. (41 N.m). On vehicles with SIR, ensure that wiring is not trapped between air bag module and steering wheel. Check AIR BAG light for system faults. See AIR BAG SYSTEM under SAFETY PRECAUTIONS.
