RIDING HEIGHT

Before attempting to check or adjust riding height, vehicle must be in static loaded condition. To load vehicle, fuel tank must be full, and weights placed in vehicle to simulate full passenger load (620 lbs. on 4 Dr. and 310 lbs. on 2 Dr.). Disconnect front and rear shock absorber. Disconnect stabilizer rods of front and rear suspension. Bounce vehicle several times and allow suspension to take up a static position.

All Models (Front) - Measure distance from lower control arm bushing to floor and front bottom of steering knuckle to floor. The difference between these two measurements should coincide with specifications. If adjustment is necessary, remove spring on affected side. See Alfa Romeo in SUSPENSION Section. Using suitable spacer between spring and its seat, adjust height to specifications. After reinstalling spring, check front suspension height.

All Models (Rear) - Measure distance between rear axle housing and rubber bumper pad. If measurement is not within specifications, remove spring on affected side. See Alfa Romeo in Suspension Section. Using suitable spacer bewtween spring and its seat, adjust height to specifications. After reinstalling spring, recheck clearance.

CASTER

Caster angle should be checked under static load with shock absorbers disconnected at one end. Difference in caste angle between left and right front wheels, should not exceed 0°20'. If caster angle is not within specifications, loosen lock nuts on upper control arm strut rods and lengthen or shorten strut rods to obtain specified angle. Retighten lock nuts.

CAMBER

Camber angle difference between left and right front wheels should not exceed 2/3°. Adjust camber angle to specifications by adding or removing shims between lower control arm and frame.

TOE-IN

Place wheels in straight-ahead position and measure toe-in. If toe-in is not to specifications, adjust by loosening lock nuts and adjusting tie-rods. Tighten lock nuts and recheck toe-in.
