Shocks and Struts

 

Proper working shock absorbers and struts are an integral part of a vehicle’s suspension.  Whether it is a family car, light truck, SUV or motorhome, good shocks and struts will provide comfort and safety while you drive.  Here at Dale’s Auto Sevice we supply OEM, aftermarket, high performance and heavy duty shock and strut applications for all different types of vehicles.  Here are some of the brands we offer:

Many different types of shock absorbers are available.  But how do I know which one I need?  The answer is simple.  We are experienced in front end  suspension repair and will match the proper shock or strut for your vehicle.

WHAT ARE THE SIGNS OF WORN OUT SHOCKS & STRUTS:

Trouble stopping:  Worn shock absorbers can add as much as 20% to your stopping distance.  That’s the sort of fault that can be fatal and requires immediate attention.

Nose-diving and swerving:  If the front of your car dips when you brake or slow down, or your vehicle swerves under brakes, you may have a shock absorber problem.

Bad vibrations:  Uncomfortable steering wheel vibration could be shock absorbers.

Side sliding:  If your car veers in side winds, particularly when the wind isn’t so strong, you could have shock absorber problems.

Shaking or Bouncing:  Notice that your car ‘rock and rolls’ over bumps, railway tracks or uneven surfaces?  Not hugging the bends?  Time to get those shock absorbers checked.

Shock Absorbers and How They Work

 

The springs support the weight of the vehicle, maintain ride height, and absorb road shock. Springs are the flexible links that allow the frame and the body to ride relatively undisturbed while the tires and suspension follow the bumps in the road.

The term bounce refers to the vertical (up and down) movement of the suspension system. The upward suspension travel that compresses the spring and shock absorber is called the jounce, or compression. The downward travel of the tire and wheel that extends the spring and shock absorber is called rebound, or extension.   When the spring is deflected, it stores energy. Without shocks and struts the spring will extend and release this energy at an uncontrolled rate. The spring’s inertia causes it to bounce and overextend itself.

The shock absorbers and struts reduce and slow down the vibrations from the springs, which is why technically they are correctly referred to as vibration dampers. Vibration dampers convert kinetic energy into thermal energy through fluid friction. This involves the flow of oil being slowed down by the valve passages inside the damper. The valve passages in the shock absorber are specifically designed to ensure that the vibrations transmitted by the spring are reduced right from the start. The shock absorbers can heat up to between 100 and 120 degrees C in the process.
