TIRE INFLATION (COLD)
Before attempting to check or adjust wheel alignment, check that tire pressure are to specifications given on driver's door lock pillar
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 to static position
All Models (Front) - Measure distance from lower control arm bushing to floor and from 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 between spring and its seat, adjust height to specifications. After reinstalling spring, recheck clearance

Start with steering link on steering box side, and set corresponding wheel to initial toe-in of 06". mEasure length of this steering link. Set steering link on opposite side to .20" less than this measurement. Now adjust center steering link to obtain .06' toe-in on wheel nearest steering box. With toe-in set, measure length of each steering link. If not within specifications, cause may be due to body distortion. Repair as necessary.
