Steering Gear High Point Centering
1. Set fro n t wheels in straight ahead position. This can be
checked by driving vehicle a short distance on a flat
surface to determ ine steering wheel position at which
vehicle follows a straight path.
2. With fro n t wheels set straight ahead, check position o f
the flat on the w orm shaft and flexible coupling. This flat
should be at the to p side o f the shaft at the
position and lined up w ith the flat in the coupling lower
clamp.
2. If the gear has been moved o ff high p o in t when setting
wheels in straight ahead position, loosen adjusting sleeve
clamps on b o th left and right han d tie rods, then turn
b oth sleeves an equal num ber o f turns in the same
direction to bring gear back on high point.
C A U T IO N : Turning the sleeves an unequal num­
ber o f turns or in d iffe ren t directions w ill disturb
the toe-in setting of the wheels. The tie rod sleeve
clamps must be positioned between the locating
protrusions at each end o f the sleeve. The clamp and
sleeve openings must be aligned and facing forward
(fig. 26).
C A U T IO N : T he tie rod adjusting sleeve clamp fasten­
ers are im portant attaching parts in th at they could
affect the performance o f vital components and
systems, an d /o r could result in major repair expense.
They must be replaced w ith one o f the same part
number or w ith an equivalent part if replacement
becomes necessary. Do not use a replacement part
o f lesser q u ality or substitute design. Torque values
must be used as specified during reassembly to
assure proper retention of this part.
4. R eadjust toe-in as outlined in Section 3 (if necessary).
Steering Wheel Alignment
N O T E : Check steering gear for high p oin t center­
ing before checking steering wheel alignment.
1. Set wheels in a straight ahead position by driving the
vehicle a short distance.
2. Check the steering wheel position; if o ff m ore th an one
inch from horizontal (fig. 3), remove the steering wheel
(see " Steering W heel-Removal" ) and reposition.
C A U T IO N : The steering wheel to steering shaft
fastener is an im portant attaching part in th at it could
a f f e c t the performance o f vital components and
systems, and/or could result in major repair expense.
It must be replaced w ith one o f the same part number
or w ith an equivalent part if replacement becomes
necessary. Do not use a replacement part o f lesser
quality or substitute design. Torque values must be
used as specified during reassembly to assure proper
retention of this part.
