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”
