When to replace worn shocks or struts
There are four main reasons that determine when to replace them:
1) To upgrade performance;
2) To restore the vehicle??s designed performance (usually after 50,000 miles);
3) When the vehicle has excessive ride control conditions (i.e. nose dive, body roll, etc.); or
4) When the vehicle has a failed unit (i.e. dripping hydraulic fluid, tire cupping, excessive bounce, etc.).
Testing has shown that original equipment gas-charged shocks and struts degrade measurably by 50,000 miles. For many popular-selling vehicles, replacing these worn shocks and struts can improve the vehicle’s handling characteristics and comfort. Unlike a tire, which rotates a specific number of times per mile, a shock absorber or strut may compress and extend several times per mile on a smooth road, or several hundred times per mile on a very rough road. There are other factors that affect the life of a shock or strut, such as, regional weather conditions, amount and type of road contaminates, driving habits, loading of the vehicle, tire / wheel modifications, and the general mechanical condition of the suspension and tires.
Why replace worn shocks or struts
Performance degrades slowly over time. When shocks and struts aren’t controlling the tire and body movement very well due to wear, all ride control conditions are affected. Stopping ability will be reduced. The vehicle’s stability, handling and control abilities all become reduced so the driver will have to compensate or drive more slowly to maintain control. Tire performance is reduced and because of excessive movement, all other attached steering & suspension components are affected.
