Shock absorbers, unlike other vehicle parts, do not have a set expiration date or set mileage. Depending on the amount and under what conditions you drive, they can last far past the 50,000 mile standard. The following are indicators that your shock absorbers need to be replaced:
Bumpy Ride – When your shock absorbers are nearing the end of their useful life, the ride in the vehicle will become bumpy. In fact, as this worsens, you will feel nearly all defects or imperfections on the road. Especially hard drops off of speed bumps.
Braking Problems – Ineffective or bad shock absorbers allow the front-end of your vehicle to “dip” or “squat” when the brakes are applied. The added stress on your brakes can cause a longer stopping distance of 20% or greater.
NOTE: This becomes a significant hazard when driving conditions are combined with rain, snow, or ice.
Steering Problems – Shock absorbers help stabilize your vehicle by maintaining balance and center of gravity. When they fail, you may feel your car sway, dip, or lift as you make turns at different speeds and degrees.
Unusual Tread Wear – Over time, due to your car’s loss of balance, your tires may begin to show strange and uneven wear patterns.

Tip: On your next oil change, request that the mechanic rotate your tires, inspect the tread wear, and evaluate the suspension system.
Fluid Leaks – Another telling sign that you need new shock absorbers is when they leak oil. If you see oil on the lower portion of the absorbers, on the inner walls of your tires, or spots on the ground in their location when you park, this is a strong indication that you need to replace your shock absorbers.
