Check & Adjust Camber & Caster At Front Axle: Adjustments
For check and adjustment procedures, refer to illustration. See Fig 1 or Fig 2 . For repair requiring bolt replacement. See INSTALL REPAIR BOLT (RWD) or INSTALL REPAIR BOLT (4MATIC) .
- Observe general information on chassis alignment. See GENERAL INFORMATION ON CHASSIS ALIGNMENT .
- Check riding height (vehicle level) at front and rear axles with electronic inclinometer and adjust if necessary. See RIDING HEIGHT ADJUSTMENTS .
- Check camber and assign to tabular value. Check camber at vehicle riding height (vehicle level).
- Check permissible difference in front axle camber between right and left sides of the vehicle.
- Check caster and assign to tabular value. Check permissible difference in front axle caster between right and left sides of the vehicle. If specification are beyond tolerance install Repair Bolt (repair bolt is necessary for camber/caster adjustments).
- Raise vehicle at front axle. Install repair bolt (19c), if found necessary. Refer to procedure and illustrations. See INSTALL REPAIR BOLT (RWD) .
- Screw on the nut (19b) from the repair kit as far as it will go, but do not tighten it so that the rubber mount on the torque strut (18) or spring link (17) can turn when the suspension is compressed and rebounded.
- Recheck riding height (vehicle level) at front axle after adjusting the camber and caster. The vehicle level must match the dimension established on the initial measurement. See CHECKING RIDING HEIGHT .
- Tighten nut (19b) from repair kit, the repair bolt (19c) must not be turned after fixing. When tightening the nut (19b) from the repair kit, always counter hold (with tool) the repair bolt (19c) otherwise the locating tabs in the rubber mount on the torque strut (18) or spring link (17) will be sheared off. See Figure .
- Tighten self-locking nut (19b). See TORQUE SPECIFICATIONS .
- Check toe on front and rear axles and make adjustments if necessary. See GENERAL INFORMATION ON CHASSIS ALIGNMENT .
