8-10. REAR WHEEL TOE-OUT ALIGNMENT (Cont’d) NOTE • To ensure proper alignment, vehicle must be at curb weight or normal operating weight. • Vehicle must be on level ground with wheels set straight ahead. • Steps 1 through 3 will determine centerline of tire. • Point of measurement for checking toe-out will be where lines marked in steps 1 and 3 intersect. 1. Mark line (4) on center tread (1) of tire (2) 16-1/2-in. (42 cm) from ground. 2. Measure total width of tire tread (3) and record. 3. Mark line (5) on center tread (1) at one-half total tread width (3). 4. Repeat steps 1 through 3 for opposite tire. 5. Measure distance between points of measurement on front side of tires (2) and record. 6. Rotate tires (2) by moving vehicle forward until points of measurement are 16-1/2 in. (42 cm) above the ground at rear side of tires (2). Repeat steps 1 through 4 for side of tires. 7. Measure distance between points of measurement on rear side of tires (2) and record. NOTE • If measurement is larger on rear side of tires than measurement on front side of tires, tires have toe-in. • If toe-out alignment does not meet specifications, repeat checking procedures to eliminate any possible reading errors. 8. Subtract meaurement obtained in step 7 for rear side of tires (2) from measurement obtained in step 5 for front side of tires (2). The result of this subtraction represents inches of toe-out. Refer to table 8-2 for toe-out specifications. If toe-out does not meet the specifications, adjust toe-out (task c.). 9. If toe-out is within specifications, refer to task c. and perform step 5. b.
