PROCEDURE:
1.
Park the vehicle on a clean, dry, solid surface-preferably concrete. Set the parking brake and block the wheels.
2.
Tilt the hood or cab using the procedures in the Vehicle Manufacturer's Service Manual.
3.
Using the tape measure, set the vehicle's wheels straight ahead. Use a spot on the frame and a spot on the
tire tread to check wheel position.
NOTE:
When using an alignment rack, omit Steps 1,2,3,4, & 5.
4.
Jack the front end up until the tires have cleared the surface.
NOTE:
Make sure the pins are installed in turn plates and the pointers are set on 0.
5.
With the lock pins in place, slide the turn plates under the front tires until the plates are centered in the
middle of the tire.
WARNING
DO NOT PUT HANDS OR OTHER BODY PARTS UNDER THE TIRES WHILE THE
UNIT IS RAISED.
6.
Slowly lower the jack until the front tires rest on the turn plates and remove the jack.
7.
Remove the lock pins from the turn plates and allow the turn plates to swivel.
NOTE:
Two people are required to properly set wheel stops.
8.
Have one person turn the steering wheel to a full left turn, holding the steering wheel in that position.
9.
The other person will look at the pointer on the left turn plate.
10.
The pointer will indicate the exact wheel angle for the left turn.
11.
Repeat steps 8, 9 & 10 for the right turn.
12.
Compare the readings with those specified by the manufacturer.
13.
If adjustments are required, use procedures as described in the Vehicle Manufacturer's Service Manual.
NOTE:
Turning the bolt in will increase the wheel cut angle. Turning the bolt out will decrease
the wheel cut angle.
