Description:
Automobiles and light trucks use different types of
springs, depending on the suspension design. The coil spring is most common,
and may be used at both the front and
rear. The leaf spring is the oldest type of spring and
is most commonly used at the rear. The torsion bar, although
not a traditional spring, is used on the front
of some cars and light trucks. Some vehicles have air suspension
systems and use air springs, which combine a coil
spring and a flexible air chamber.
Purpose: Springs support the weight of
the
vehicle and allow the suspension system to
move and adapt to road irregularities, compressing when the wheels hit a
bump and expanding when the wheels encounter a dip. Vehicles with air
springs also have the ability to change ride height based on
driving conditions.
Maintenance Tips/Suggestions: Springs weaken gradually over time and
may sag, causing your car’s ride height to drop. Springs can also
break as they age. Ride height influences steering and suspension
operation, so it’s important to have it checked along with a
thorough visual inspection of the springs. Have this
done once a year, at the same time as a wheel alignment.
Weak or damaged springs can cause “bottoming out”, abnormal tire wear,
improper handling and increased wear of steering and suspension parts. You
may want to consider upgrading the springs on your vehicle to increase
its load-carrying abilities. These springs
provide increased
capacity without affecting
ride quality.
If your car needs its MacPherson struts
replaced, it may also be a good time to replace the
coil springs. Since they usually need to be removed when changing
struts, you can save labor costs by installing new springs at
the same time. For the best handling,
ride and performance, have your vehicle’s steering and suspension system
maintained by a qualified service professional.
