lating ball guides.
MEASURE
Place a low calibration (50 in. lbs.) torque wrench
and socket on the steering wheel nut. Rotate the
wrench and nut through a 90 degree arc (1/4 turn).
This will measure the worm shaft bearing preload.
ADJUST WORMSHAFT BEARING PRELOAD
TORQUE
(1) Adjust the preload by tightening the adjuster
plug. The preload should be 0.6 to 1 Nzm(5to8in.
lbs.) torque.
Steering column/shaft misalignment or damage will
increase the amount of torque required to rotate the
steering wheel. If the rotating torque is exceptionally
high, inspect the steering column/shaft alignment. If
the alignment is correct, remove the steering gear,
determine the cause of the high preload torque, and
repair as necessary.
(2) Tighten the adjuster locknut to 68 Nzm (50 ft.
lbs.) torque. Measure the preload torque. If neces-
sary, adjust the preload torque again.
ADJUST OVERCENTER DRAG TORQUE

other and count the total numbers of turns. Turn the
wheel back in reverse direction 1/2 the total number
of turns to center the steering gear.(2) Turn the over center adjusting screw in to re-
move all lash between the ball nut and pitman shaft
sector teeth. Hold the adjustment screw and tighten
the lock nut to 34 Nzm (25 ft. lbs.) torque.
(3) Check the torque at the steering wheel by tak-
ing the highest reading as the wheel is turned
through the center position.
(4) The overcenter drag torque should be 0.5 to 1
Nzm (4 to 10 in. lbs.).
(5) If necessary, loosen the lock nut and adjust the
over center adjuster screw to obtain the proper
torque. Re-tighten the lock nut to the lock nut.
(6) After tightening the locknut, measure the over-
center drag torque again and readjust the torque, if
necessary.

VEHICLE VIBRATION
Vehicle vibration can be caused by:
²Tire/wheel unbalance or excessive runout
²Defective tires with extreme tread wear
²Nylon overlay flat spots (performance tires only)
²Incorrect wheel bearing adjustment (if applicable)
²Loose or worn suspension/steering components
²Certain tire tread patterns
²Incorrect drive shaft angles or excessive drive
shaft/yoke runout
²Defective or worn U-joints
²Excessive brake rotor or drum runout
²Loose engine or transmission supports/mounts
²And by engine operated accessories
Refer to the appropriate Groups in this man-
ual for additional information.
VIBRATION TYPES
There are two types of vehicle vibration:
²Mechanical
²Audible.
Mechanical vehicle vibration can be felt through
the seats, floor pan and/or steering wheel.
Audible vehicle vibration is heard above normal
background noise. The sound can be a droning or
drumming noise.
Vibrations are sensitive to change in engine torque,
vehicle speed or engine speed.
ENGINE TORQUE SENSITIVE VIBRATION
This vibration can be increased or decreased by:
²Accelerating
²Decelerating
²Coasting
²Maintaining a constant vehicle speed
VEHICLE SPEED SENSITIVE VIBRATION
This vibration condition always occurs at the same
vehicle speed regardless of the engine torque or en-
gine speed.
ENGINE SPEED (RPM) SENSITIVE VIBRATION
This vibration occurs at varying engine speeds. It
can be isolated by increasing or decreasing the en-
gine speed with the transmission in NEUTRAL posi-
tion.
VIBRATION DIAGNOSIS
A vibration diagnosis should always begin with a
10 mile (16 km) trip (to warm the vehicle and tires).
Then a road test to identify the vibration. Corrective
action should not be attempted until the vibration
type has been identified via a road test.
During the road test, drive the vehicle on a smooth
surface. If vibration exists, note and record the fol-
lowing information:²Identify the vehicle speed range when the vibra-
tion occurs
²Identify the type of vibration
²Identify the vibration sensitivity
²Determine if the vibration is affected by changes
in vehicle speed, engine speed and engine torque.
When the vibration has been identified, refer to the
Vibration Diagnosis chart for causes. Consider cor-
recting only those causes coded in the chart that are
related to the vibration condition.
Refer to the following cause codes and descriptions
for explanations when referring to the chart.
TRRÐTire and Wheel Radial Runout:Vehicle
speed sensitive, mechanical vibration. The runout
will not cause vibration below 20 mph (32 km/h).
WHÐWheel Hop:Vehicle speed sensitive, me-
chanical vibration. The wheel hop generates rapid
up-down movement in the steering wheel. The vibra-
tion is most noticeable in the 20 - 40 mph (32 - 64
km/h) range. The wheel hop will not cause vibration
below 20 mph (32 km/h). Wheel hop is caused by a
tire/wheel that has a radial runout of more than
0.045 of-an-inch (1.14 mm). If wheel runout is accept-
able and combined runout cannot be reduced by re-
positioning the tire on wheel, replace tire.
TBÐTire/Wheel Balance:Vehicle speed sensitive,
mechanical vibration. Static tire/wheel unbalance
will not cause vibration below 30 mph (46 km/h). Dy-
namic tire/wheel unbalance will not cause vibration
below 40 mph (64 km/h).
TLRÐTire/Wheel Lateral runout:Vehicle speed
sensitive, mechanical vibration. The runout will not
cause vibration below 50 - 55 mph (80 - 88 km/h). Ex-
cessive lateral runout will also cause front-end
shimmy.
TWÐTire Wear:Vehicle speed sensitive, audible
vibration. Abnormal tire wear causes small vibration
in the 30 - 55 mph (88 km/h) range. This will pro-
duce a whine noise at high speed. The whine will
change to a growl noise when the speed is reduced.
WÐTire Waddle:Vehicle speed sensitive, mechan-
ical vibration. Irregular tire uniformity can cause
side-to-side motion during speeds up to 15 mph (24
km/h). If the motion is excessive, identify the defec-
tive tire and replace it.
UAJÐUniversal Joint (Drive Shaft) Angles:
Torque/vehicle speed sensitive, mechanical/audible vi-
bration. Incorrect drive shaft angles cause mechani-
cal vibration below 20 mph (32 km/h) and in the 70
mph (112 km/h) range. The incorrect angles can also
produce an audible vibration in the 20 - 50 mph (32 -
80 km/h) range. Caster adjustment could be required
to correct the angles.
UJÐUniversal Joints:Engine torque/vehicle
speed sensitive, mechanical/audible vibration. If the
