                                 Wheel Alignment


1.  Check front wheels for rim run out.  Maximum tolerance is .406 mm (.016 inch).

2.  Check tire pressures.  See specifications.

3.  Check and ensure no abnormal wear in steering joints/suspension.

4.  Place vehicle on flat surface.

5.  Check and, if necessary, adjust setting height 140 mm (5.5 inches).  Figure 1.
    This measurement must be taken from the center of the front crossmember.

    NOTE:  It may be necessary to life the front of the vehicle or to load the
           luggage compartment to obtain the specified setting height.

6. Proceed with wheel alignment per the directions of the manufacturer of the alignment equipment used. NOTE: Where equipment directions indicate to jounce the suspension, substitute with, check and ensure specified setting height is maintained.
