steering column shaft assembly.
Inspection Procedure
1. Remove the lower and upper column covers.
CAUTION
Do not release the tilt lever until the steering
column has been installed to complete this
inspection procedure.
2. Ensure that the tilt lever is in the lock position.
NOTE: If not, place the tilt lever in the lock
position.
3. Loosen the two steering column mounting bolts
(upper) by two turns.4. Hold the one-way capsules as shown, and then
try to lock them. If there is a slack in either of the
capsules, replace the steering column shaft
assembly.
NOTE: When installing a new steering column
shaft assembly, place the tilt lever in the lock
position, if it is not in place.
CAUTION
•Be careful that nothing is pinched between
the one-way capsules and the body.
•Do not release the tilt lever until the steering
column has been installed to complete this
inspection procedure.
5. If no problem is found during the inspection,
tighten the steering column mounting bolts to the
specified torque.
