and reinstalled. Brake shoes can be manually adjusted by rotating
adjuster screw. Remove access slot cover.
3) Using a small blade screwdriver, push in on adjustment
lever to separate from adjustment screw. Turn adjustment screw until
brake drum is locked tight. Back screw off until wheel rotates freely.
If brake drum is to be removed, back off adjustment screw several
notches for adequate clearance.
HEIGHT SENSING PROPORTIONING VALVE - COMANCHE
NOTE: Anytime adjustment is required the lever bushing must be
replaced.
Adjustment must be made on a drive-on lift or a flat level
surface with vehicle at curb weight. Remove height sensing
proportioning valve shaft nut and washer. Disconnect valve lever and
remove spring. Remove and discard bushing.
Rotate valve shaft to permit installation and proper
alignment of valve adjusting gauge (J-35853-2).
NOTE: The gauge (J-35853-2) must be properly seated on the "D"
shape of the shaft and the lower mounting bolt of the valve.
See Fig. 2. Also, all linkage components, excluding the
spring, must be connected to the axle housing before
installation of bushing.
Place lever bushing in lever. Using bushing installation
tool (J-35853-1) press bushing along with lever onto valve shaft.
Remove lever and adjusting to (J-35853-2) then install the spring.
Install lever, washer and retaining nut. Tighten retaining nut to 100
Inch-lbs. (11 N.m). Connect spring to lever arm.

Wheel Alignment
PRE-ALIGNMENT INSPECTION PROCEDURES
PRE-ALIGNMENT CHECKS
Before making wheel alignment adjustment, perform the
following checks:
1) Tires should be equal in size and runout must not be
excessive. Tires and wheels should be in balance, and inflated to
manufacturer's specifications.
2) Wheel bearings must be properly adjusted. Steering linkage
and suspension must not have excessive looseness. Check for wear in
tie rod ends and ball joints.
3) Steering gear box must not have excessive play. Check and
adjust to manufacturer's specifications.
4) Vehicle must be at curb height with full fuel load and
spare tire in vehicle. No extra load should be on vehicle.
5) Vehicle must be level with floor and with suspension
settled. Jounce front and rear of vehicle several times and allow it
to settle to normal curb height.
6) If steering wheel is not centered with front wheels in
straight-ahead position, correct by shortening one tie rod adjusting
sleeve and lengthening opposite sleeve equal amounts.
7) Ensure wheel lug nuts are tightened to torque
specifications.

WHEEL ALIGNMENT
WHEEL ALIGNMENT
Wheel alignment is defined as the measurement, analysis, and
adjustment of steering and suspension angles to conform to OEM
specifications. These angles usually include, but are not limited to:
caster, camber, toe, and thrust angle. Where these angles are not
adjustable and not in specification, component replacement or
correction kits may be required. Errors in set-back and steering axis
inclination (SAI) are often attributable to failed or damaged
components and must be corrected prior to performing an alignment.
Failure to replace or correct suggested parts or service may
prevent a proper alignment.
Before performing an alignment check, inspect and verify the
following:
* Tire pressure and size
* Vehicle loading
* Ride height
* Steering and suspension parts
If the inspection reveals that all the above are within
published specifications, a wheel alignment check and an alignment, if
needed, may be performed.
CAUTION: Under no circumstances should a technician bend or heat
any steering or suspension component, unless specified by
the vehicle manufacturer, for example, Ford forged twin
"I" beam axles. All measurements and specifications must
be noted on the inspection report.
