FRONT WHEEL ALIGNMENT VEHICLE CENTERLINE
1) Project the laser beams from the Left and Right Toe
Gauges onto the Rear Retro-screens. If the beam does
not strike the rear mirror, check the level of the Laser
Toe Gauge. (See Fig. 32)
2) Note the readings on the scales of the rear screens.
Add both readings and divide by two.
3) Adjust both tie rods or tie rod adjusting sleeves
equally so that the rear screens register the desired
reading determined in Step 2.
EXAMPLE:
One rear wheel screen registers 5 (See Fig. 33) and
the other one registers 7 (See Fig. 34), the total is 12.
Divide by 2 and adjust both tie rods equally until the
laser beam falls on 6 on each retro screen.
4) Re-check front wheel toe to be sure it remains on
zero. If not, re-adjust front wheel toe to zero. Re-
check the rear retro-screens for equal readings.
This is a “Two Wheel Alignment”
