TOOLS FOR FRONT-END ALIGNMENT
To measure alignment angles, you will need special
equipment, A wheel alignment rack (fig. 12-8) would be
ideal. It positions a vehicle so that you can take
measurements accurately and easily. However, it is
doubtful that you will find such a setup in the battalions.
You most likely will find the magnetic caster-camber
gauge (fig. 12-9), a set of turntables (fig. 12-10), and a
toe-measuring gauge (fig. 12-1 1). These three tools are
the essentials. There are a large variety of tools on the
market to aid you in making the actual caster, camber,
and toe adjustments. Some are necessary; others can be
substituted from your kit 13.
ALIGNMENT PROCEDURES
Check suspension and steering systems before
making any of the following alignment adjustments:
1. Inspect the tires for correct size and inflate them
to correct the air pressure. If the front tires are worn from
misalignment, rotate or replace them. A tire worn on one
side or the other will tend to pull to the worn side, even
after the vehicle has been correctly aligned.
2. Inspect the wheel bearings, and correct
excessive end play before making any other inspections
or adjustments.
