Alignments:
In
its most basic form, a wheel alignment consists of
adjusting the angles of the wheels so that they are perpendicular to
the ground and parallel to each other. The purpose of these
adjustments is maximum tire life and a vehicle that tracks straight
and true when driving along a straight and level road.
Wheel Alignment is often confused with Wheel Balancing.
The two really have nothing to do with each other except for the fact
that they affect ride and handling. If a wheel is out of balance, it
will cause a vibration at highway speeds that can be felt in the
steering wheel and/or the seat. If the alignment is out, it can cause
excessive tire wear and steering or tracking problems.
