STEERING COLUMN REPLACEMENT 

Tools Required 

J 42640 Steering Column Lock Pin 

Removal Procedure 

CAUTION: Refer to SIR Caution in Cautions and Notices.

NOTE:

Once the steering column is removed from the vehicle, the column is extremely 
susceptible to damage. Dropping the column assembly on the end could 
collapse the steering shaft or loosen the plastic injections, which maintain 
column rigidity. Leaning on the column assembly could cause the jacket to 
bend or deform. Any of the above damage could impair the columns collapsible 
design. Do NOT hammer on the end of the shaft, because hammering could 
loosen the plastic injections, which maintain column rigidity. If you need to 
remove the steering wheel, refer to the Steering Wheel Replacement procedure 
in this section.

NOTE:

The front wheels of the vehicle must be maintained in the straight ahead 
position and the steering column must be in the LOCK position before 
disconnecting the steering column or intermediate shaft. Failure to follow these 
procedures will cause improper alignment of some components during 
installation and result in damage to the SIR coil assembly.
