Cars involved in accidents resulting in frame damage,
major body or sheet metal damage, or where the steering
column has
been impacted may also have a damaged or
misaligned steering column.

If you are able to move lever to "Park" posltion without raising lever, it IS an indication that the upper I shift tube plastic bearing is broken.
4. Check for jacket collapse by measuring the dlstance ( from edge of the back-up switch wlndow to the lower edge
of upper jacket. (Refer to View C for dimenslons.) If jacket dimenslons are not within specificat~ons a NEW jacket I must be instatled. Visually inspect for sheared injected plastlc I------- in the shift tube (V~ew D), and the steering shaft (View E). If either one, or both are sheared replace w~th NEW parts. I

INTERMEDIATE SHAFT ASSEMBLY
REMOVE
1. Disengage stone shield from boss on steering gear
housing or adapter. Remove pinch bolt from flexible
coupling.
2. Remove coupling clamp to steering shaft attaching bolt
and nut.
3. Push up
on intermediate shaft to remove from steering
gear stub shaft then pull down until coupling is removed
from steering shaft. INSTALL
1. Install
intermediate shaft on steering shaft and install bolt
and nut and torque nut to 60 N.m (44 ft. Ibs.)
2. Pull down on intermediate shaft to install on steering gear
stub shaft. Coupling mut be fully seated so splines are
not visa
