How They Work

Shocks provide resistance by forcing hydraulic fluid (oil) through valves in the piston as it moves up and down. Because the oil cannot be compressed, only a certain amount of fluid can be forced through these valves, which creates resistance to the vehicle movement.

How to Tell if Shocks and Struts Need Replacement

Under normal conditions, shocks and struts wear out gradually. However, many factors can affect how much wear is actually occurring and at what rate it is occurring.

If two people buy the same vehicle new off the dealer lot, but one lives and drives in the city with a short commute, while the other lives in the country, 50 miles from work and travels part of that over bumpy, muddy back roads, its a good guess that the second driver will have to replace shocks long before the first driver.

The piston rod can easily be nicked or damaged by flying gravel allowing grit and dirt to damage the piston seal.

Among signs of worn shocks or struts:

Do you experience excessive bounce (three or more bounces) when crossing an intersection?
When stopping quickly does your vehicle rock back and forth?
While applying your brakes firmly at higher speeds, does your vehicle drift left or right?
When changing lanes quickly does your vehicle rock or sway from side to side?

Many components contribute to handling. Having your vehicle inspected by a Subaru Certified Technician if you experience any of the above signs is good preventive maintenance.
