Shocks are one of the most overlooked components on modern vehicles. All of us can take for granted how amazing vehicles of the last few decades ride and handle compared to generations past. Shocks and struts are largely responsible for the performance we now appreciate. Properly functioning shocks and struts are also a major contributor to braking/stopping distance, emergency handling and collision avoidance.
Under normal conditions on a smooth road, shocks can cycle an average of 1,700 times per mile traveled. Every time the wheel and tire react to bumps and motion in the road, the shock and spring is cycled. During a cycle, the piston will move, and the valving inside the body will pass fluid from one side of the unit to the other. During this cycle, the spring is compressed then extended.
SIGNS THAT A STRUT OR STRUT MOUNT ARE FAILING:
Excessive force or notchy feeling in certain areas of the steering (especially when the vehicle is stationary).
Memory steering: When the steering wheel does not want to return to its center point when released.
Visually: the top bushing observed through the strut tower (when possible) has separated from the busing were the rod passes though the outer shell. Some cracking is normal but excessive cracking can be a sign of a failing strut mount.
When it is determined that shocks and struts are to be replaced, the next decision is to what extent the repairs should be pursued. For most makes and models a ‘loaded strut’ is offered by many major suspension equipment manufacturers. A loaded strut includes the shock, spring, and strut mount. one part of the suspension system has already failed, and the vehicle has age and/or mileage。
