Jeep Steering Columns
All models use collapsible steering columns. All columns have integral ignition switch and locking device. Optional tilt wheel is available with both A/T and M/T. Transmission shift linkage is integral on all models except those with floor shift.
Refer to TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL TROUBLE SHOOTING section.

STEERING COLUMN (FLOOR SHIFT)
The steering column with a floor mounted gearshift is basically the same as previously described. Standard columns and service procedures are identical except as described below.
* In place of rotating shift housing, there is a plastic shroud which is fixed to lock housing. Shroud covers jacket and lock inhibitor assembly. It is held in place by a tab that fits under side cover and one screw. Shroud can only be replaced by removing lock housing from jacket.
lock inhibitor assembly consists of a lever that engages
lock levers (preventing locking of steering shaft), a button
to operate lever and a return spring. Assembly is attached to
lock housing in same location as shift gate is on column
shift. Lower steering shaft bearing is mounted in an aluminum
is attached between shift housing and column jacket.
This spring keeps housing rotated counterclockwise against
