Checking / Adjusting

Lifting the rear suspension
Toe-in can be adjusted. Camber cannot be adjusted however.

Note! Take all measurements with the car empty. The fuel level in the tank does not affect the measurement. Check the tire pressure on all tires. See the specifications for the relevant tire.

Check





Check for play in:
- The wheel bearings (if there is play, the complete hub must be replaced)
- The bushings for the trailing arms and transverse arms.

Test equipment




Set up and calibrate test equipment according to its instructions.

Checking camber angle




The correct value is: -1° ± 0.5° .
If the camber angle is outside these parameters, check the trailing arms for damage.

Checking and adjusting the toe-in




Check that the instruments are adjusted in relation to each other on the front and rear axles. This important so that toe-in can be checked and adjusted in relation to the axis of symmetry.
The correct toe-in is 0.07° (4.2') measured across both wheels. Maximum deviation is 0.09° (5.4') per wheel.

Adjustment

Note! The example below describes the adjustment of both sides.




Slacken off the nuts on the mounting screws for the transverse arm slightly on both sides.
Adjust by moving the transverse arms in their mountings (backwards or forwards) until the correct value is achieved.
Tighten one of the screws to each transverse arm mounting so that it is secured to the other trailing arm.
Replace all the other nuts and bolts (that are not tightened) with new ones. Applies to each transverse arm mounting. Tighten the nuts. Tighten to 50 Nm . Angle-tighten to 120° . Use protractor 951 2050 BEVEL PROTRACTOR 951 2050 Bevel Protractor.
Replace the two nuts and bolts previously tightened on each transverse mounting. Tighten the nuts to the same values as above.
