944 S2 Cabriolet L4-2990cc 3.0L DOHC (1991)
Alignment: Service and Repair
Alignment Note
Accurate front axle height adjustment is critical to toe-in, camber, and caster adjustments. Ensure tire pressures are at their specified values,
fuel tank is full, spare tire is in place, and a weight approximately the same as the driver, positioned on the driver's seat.
Camber
Camber adjustment is made by loosening joint between spring strut and trailing arm, then turning camber eccentric.
Toe
Adjust toe by moving trailing arm in slots of spring strut.
Camber & Caster
Fig. 2 Front Caster & Camber Adjustment. 924S & 944 Models
1.
Adjust camber by turning eccentric bolt on lower strut mounting.
2.
On models with steel control arms, adjust caster by moving rear of suspension control arm from side to side.
3.
On models with aluminum control arms, adjust caster by loosening self locking nuts and turning caster eccentric until caster is within
specifications, Fig. 2, then torque nuts to 62 ft. lbs.
Rear Axle Height
Rear vehicle height can be adjusted on two piece spring plate, without removal of torsion bars. If spring plate angle is as specified, vehicle height will
be correct.
Torsion Bar
944
If the torsion bar is reset by one spline at its inner end, a 9° change is obtained. If the radius arm is reset by one spline at the outer end of the
torsion bar, a change of 8 3/20° is obtained. This arrangement allows a change of 5/6° if the torsion bar and radius arm are positioned towards
each other.
1.
Position a bubble protractor on the lower edge of door sill, Fig. 6.
2.
Rotate bubble level carrier on VW 261 or an equivalent protractor to specified torsion plate angle.
3.
With torsion plate cover removed, position protractor on torsion plate, Fig. 7.
Lift the plate enough to remove play from splines.
4.
According to angle measurement at door sill, if front of vehicle is lower than rear, add door sill measurement to torsion plate value. If rear of
vehicle is lower than front, subtract door sill measurement from torsion plate value.
