THRUST ANGLE ALIGNMENT
1) Check that both Laser Toe Gauges are level. The laser beams should be visible on the rear Retro-screen
mirrors (See Fig. 35).
2) Rotate the rear Retro-screen assemblies out of level, if necessary, so that the laser beams will be reflected
back to the front Toe Gauges and be visible on the Thrust Angle Scales.
3) Note the readings on the Thrust Angle Scales. Add both readings and divide by two.
4) Adjust both tie rods or tie rod adjusting sleeves equally so that the Thrust Angle Scales register the
desired reading determined in Step 3.
EXAMPLE:
One Thrust Angle Scale registers 4 (See Fig. 36)and the other one registers 6 (See Fig. 37), the total is
10.
Divide by 2 and adjust both tie rods equally until the laser beam falls on 5 on each Thrust Angle Scale.
(See Fig. 39 and Fig. 40)
This is a Thrust Angle Alignment where the front wheel position is corrected for rear wheel misalignment.
