SET TOE-IN
1. Remove wheel cover or bezel and set gear on high
point of worm by turning steering wheel until mark on
shaft is exactly at top. This mark locates the high
point, oc middle of gear travel.
2. a. On Pontiac and Firebird loosen all tie rod clamp
bolts. To increase toe-in turn right tie rod adjuster
sleeve in direction of rotation of wheels, when car
moves forward; turn left tie rod adjuster sleeve in
opposite direction. Turn both sleeves an equal amount
until toe-in is set at proper specification.
b. On Tempest and Grand Prix loosen all tie rod
clamp bolts. To increase toe-in
-
turn left tie rod
adjuster sleeve in direction of rotation of wheels, when
car moves forward; turn right tie rod adjuster sleeve in
opposite direction. Turn both sleeves an equal amount
until toe-in is set at proper specification.
3. Make sure front wheels are straight ahead by
measuring from a reference point at same place on
each side of frame center to front of wheel rims. If
measurements are not equal, turn both tie rod adjuster
sleeves in same direction (so as not to change toe-in)
until measurements become equal. Re-check toe-in
since toe-in measurement is accurate only with wheels
in straight-ahead position.
4. Tighten all tie rod clamp bolts to 17 lb. ft. torque.
Open end of clamps on Pontiac should be 00-15"
rearward of vertical down position and on Tempest
and Grand Prix open end of clamps should be 00-15
forward from vertical down position. On Firebird the
open end of clamps should be on the high side of
adjuster sleeve and 30" either side of vertical up
position.
CHECK STEERING AXIS INCLINATION
Generally there is no need to check steering axis
inclination unless a problem exists after setting caster
and camber to specification. Failure to obtain correct
measurement indicates a bent or damaged steering or
suspension part.
CHECK TOE-OUT ON TURNS
Check toe-out after any necessary wrrections to
camber, caster, and toe-in have been made.
1. Check with any reputable front end aligning
equipment, using full floating turn tables. With front
wheels resting on turn tables, turn wheels to left until
left wheel has been turned 20" from straight ahead.
The right wheel should have turned 18" to 19".
2. Turn wheels to right until right wheel has been
turned 20" from straight ahead. Left wheel should have
turned 18" to 19".
3. Incorrect toe-out on turns may be caused by
incorrect front end adjustments, but generally indicates
bent steering arms which must be replaced.
Replacement of one or both steering arms should be
followed by a complete front end check.

WHEEL BEARING
REMOVE
1. Raise car and support at front lower control arm.
NOTE: This will maintain load on the ball joints.
2. Remove hub cap or wheel disc from wheel.
3. a. Standard Brakes: Remove dust cap from hub.
b. Disc Brakes: Remove wheel and tire assembly
before removing dust cap from hub.
4. a. Standard Brakes: Remove cotter pin, wheel
adjustment nut and washer from spindle, then remove
wheel with hub and drum assembly from spindle with
a gentle rocking motion.
CA UTION: When hub an4 wheel assembly is partially
loose on spindle, remove outer wheel bearing. DO NOT
DROP BEARING.
NOTE: In some cases it may be necessary to back off
brake adjustment to remove hub and wheel assembly.
b. Disc Brakes: Remove brake caliper assembly before
removing cotter pin, wheel adjustment nut and washer
from spindle. Then, remove disc assembly from
spindle.
CAUTION: Brake hose is still connected to caliper;
theeyore, caliper must be moved out of way and
supported so brake hose will not be damaged.
5. Remove inner bearing from hub by tapping out
inner grease seal with a brass drift. DISCARD SEAL.
6. Wipe old grease out of hub and from spindle of
steering knuckle.
7. Wash bearings in solvent and air-dry. Do not spin
dry with compressed air. Inspect bearings and races for
cracking, pitting, etching, etc.
NOTE: If necessary to replace either a bearing (inner
race and rolls assembly) or its outer race, both bearing
and outer race should be replaced together.
When inspecting or replacing bearing (inner race m d rolls
assembly), make sure the race is free to creep on spindle.
The inner race is designed to creep on the spindle in order
to g o r d a constantly changing load contact between the
race and the roller bearings. Polishing the spindle or
