As the internal components of shocks and struts wear, additional internal heat is created resulting in deteriorating ride quality, braking and handling. With this wear, the oil inside the struts and shocks aerates becoming more like foam than the liquid oil it is meant to be. The farther you drive the worse this gets. The air acts like a squishy ball, allowing excessive movement of the vehicle. When we step on the brakes or make sudden steering moves the vehicle starts to rock or roll, this lifts up one end and drops the other end. Any time this happens the tires, brakes and suspension are over loaded on the low side and you don’t have enough traction on the high side. This is the reason it takes longer to stop and you have less control with worn struts and shocks.
Unfortunately we cannot change the oil in the struts and shocks when it gets old like we do engine oil. You may have seen advertising from manufacturers advising you to replace struts and shocks after 80,000 kilometers; this is the reason; the oil is worn out resulting in the struts and shocks not working as they were intended to.
There are other considerations with worn struts and shocks; all of the extra vehicle movement creates wear in suspension and steering components, requiring replacement sooner than needed. The braking system will be over loaded in the front from having too much weight transferred from the back of the vehicle to the front when slowing down. This overloads the front brakes and causes the rear brakes to be less effective creating longer stopping distances. Additionally your tires will wear out far sooner than a vehicle with good shocks and struts.
Regular maintenance inspections, performed by experienced technicians along with the needed services will help you save time and money keeping your vehicle safe and reliable for many years to come.
