Subaru 1973-74 Wheel Alignment Guide
1973-74 SUBARU SPECIFICATIONS AND ADJUSTMENTS
TIRE INFLATION (COLD)
Before attempting to check or adjust wheel alignment, make sure tires are properly inflated. Refer to manufacturers specifications in owner's manual.RIDING HEIGHT (REAR)
Riding height is adjusted by changing the size of the angle between trailing arm center line and the marking on outer bracket (see illustration). The trailing arm and outer bracket have full serrations around the torsion bar mounting hole, while the torsion bar has one missing serration, thus allowing torsion bar to be inserted at any angle.Raising vehicle height is accomplished by turning outer end and inner end of torsion bar in direction opposite to cast-in arrow on outer end of bar. Height changes 20" (5 mm) per each serration shifted.
1) Initially set vehicle rear riding height by inserting torsion bar with its missing serration aligned with marking on outer bracket surface and trailing arm inner surface. This will give approximately the specified riding height 11.29-11.89" with bias ply tires, or 11.06-11.66" with radial tires.
2) Measure road clearance from center of trailing arm bushing to ground NOTE - Vehicle must be in unloaded condition. Raise rear of vehicle and remove rear wheel.
3) Unscrew shock absorber lower mounting nut and remove from trailing arm. Unscrew lock bolt on outer bushing.
4) Scribe mark position of torsion bar by making a mark on upper half of inner end surface and lower half of outer end surface. Outer end surface mark should be continued onto trailing arm shaft and outer bracket boss.
5) Holding trailing arm so torsion bar does not twist, disengage serrations by tapping inner end surface of torsion bar. (see illustration)
6) Pull torsion bar out of trailing arm. Determine amount of turn necessary to make proper height adjustment and turn inner end of torsion bar to this value. Then, insert outer end of torsion bar to its proper adjusted position.
7) Install rear wheel and lower vehicle. Reattach lower end of shock absorber. Recheck vehicle rear ground clearance in originally measured. If correct, tighten lock bolt on outer trailing arm bushing. If incorrect, repeat adjustment.
CASTER
Caster angle is not adjustable. If angle is not to specifications inspect suspension for wear or damage and repair or replace components as necesary.CAMBER
All Models (Front) - If toe-in is not within specifications, loosen steering link (tie rod) lock nut and turn sleeve until correct toe-in is obtained.
All Models (Rear) - If toe-in is not within specifications, loosen bolts holding torsion bar bushing to body. Bushing is fixed to body at elongated holes. Moving bushing forward decreases toe-in and moving it rearward increases toe-in. Tighten bolts and recheck toe-in

Subaru 1970-72 Wheel Alignment Repair Guide
1970-72 SUBARU SPECIFICATIONS AND ADJUSTMENTS
Before attempting to check or adjust wheel alignment, ensure that tires are properly inflated.
RIDING HEIGHT
1100 Front (1970-71) & 1300 Front (1971) - With vehicle on level ground, check riding height from center of the lower arm to floor. Measurement should be 8.94" to 9.33". To adjust, use suitable tool (925041000) and rotate adjusting cam (access to cam through opening front grill) clockwise to increase or counterclockwise to decrease riding height to specifications.1100 & 1300 Station Wagon Rear (1971) - With vehicle on level ground, measure rear riding height from center of torsion bar to floor. Measurement should read 13.0" to 13.4". Adjustment is made from inside of trunk by turning center arm adjusting bolt which is built into the crossmember.
All Other Models Rear (1970-72) -
1) If riding height dimension between level floor and center of torsion bar at outer end is not within specifications, adjustment is required.
2) Jack up rear of vehicle and remove rear wheels.
3) Remove nut holding lower end of shock absorber and remove from trailing arm while pushing up the trailing arm.
4) Loosen lock bolt on outer bushing of torsion bar and mark both end surfaces of torsion bar and on end surface of trailing arm shaft and outer bracket boss. Markings should be made on upper part of inner end, and lower part of outer end.
5) Hold trailing arm so torsion bar will not twist and disengage serrations of bar by tapping inner end surface of torsion bar. NOTE - Do not damage serrations during this procedure.
6) Vehicle height is raised by turning torsion bar in opposite direction to arrow mark on outer end surface of torsion bar. Reverse direction lowers vehicle height. The changing rate of vehicle height is .20" per tooth shifted. Adjust only inner end serrations by turning torsion bar after assuring that bar has been pulled out of trailing arm. Then insert outer end serrations into outer bracket boss by lining up trailing arm.
7) Install rear wheels and secure lower end of shock absorber.
8) Check vehicle height and if within specifications tighten lock bolt on outer bushing 13.0 to 18.1 ft. lbs.
CASTER
1300 & 1400 (1972) - Caster is nonadjustable. If alignment is not within specifications, inspect suspension for damage to crossmember, transverse link and body or improper installation of suspension parts. Replace with new parts or perform proper installation where necessary.1100 (1970-71) & 1300 (1971) - If caster is not within specifications adjust by rotating caster adjusting cam until within specifications. Cam is located on lower arm next lower arm shaft.
CAMBER
1300 & 1400 (1972) - Camber is nonadjustable. If alignment is not within specifications, check for damage to suspension parts or improper installation of parts.1100 (1970-71) & 1300 (1971) - If camber is not within specifications, adjust by rotating camber adjusting cam until within specifications. Cam is located on lower arm next to ball joint.
All Models Rear (1970-72) - Camber is adjusted by changing shims which are inserted between torsion bar inner bushing and body of vehicle. Adding shims decreases camber angle and removing shims increases angle. Adjustment procedure same for both wheels.
TOE-IN
All Models Front (1970-72) - If toe-in is not within specifications loosen tie rod lock nuts. Adjust by turning tie rod until readings are within specifications. Tighten lock nuts.All Models Rear (1970-72) - If toe-in not within specifications, loosen bolts holding torsion bar bushing to body. Bushing is fixed to body at elongated holes and moving bushing forward decreases toe-in. To increase toe-in, move bushing towards rear of vehicle. Tighten bolts and recheck toe-in.

TIRE INFLATION (COLD)
Before attempting to check or adjust wheel alignment, make sure tires are properly inflated. Refer to manufacturer's specifications given in owner's manual.
CASTER
All Models - To adjust caster, add or remove shims under upper control arm bushing brackets. Changing shims from front to rear bracket increases caster angle. Moving shims from rear to front decreases caster angle. Note - Some thickness of shims removed from front must be placed under rear and vice versa. Change in caster also affects camber.
CAMBER
All Models - To adjust camber, add or remove shims under upper control arm bushing brackets. Increasing shims under both brackets reduces camber angle and removing shims under both increases camber. NOTE - Always add or remove some thickness of shims at front and rear or caster angle will be affected.
TOE-IN
All Models - With wheels in straight-ahead position, loosen steering link (tie rod) lock nut and turn adjustable sleeve until correct toe-in is obtained. Tighten lock nuts and recheck toe-in.
NOTE - After adjustment of toe-in, measurement A (see illustration) of tie rod must not exceed 1.6" (with key grip) or 1.2" (without key grip). For tie rods opposite to each other the difference between the measurement A must not exceed .08".

Check camber to specifications.CAMBER
All Models (1963-73) - To adjust camber, add or remove shims under bearing brackets of the upper control arms. Increasing shims under both brackets reduces camber and decreasing shims under both brackets increases camber. NOTE - Always add or remove some thickness of shims at front and rear brackets. Change in camber adjustment affects caster. Recheck caster to specifications.TOE-IN
All Models (1963-73) - Position front wheels in straight ahead position. Loosen tie rod lock nut on outer end of tie rod. Turn tie rod to set toe-in to specifications. Tighten lock nuts.NOTE - After adjustment of toe-in, measurement A (see illustration) of tie rod must not exceed 1.6" (with key grip) or 1.2" (without key grip). For tie rods opposite to each other the difference between the measurements A must not exceed .08".
