Every vehicle has either shocks or struts at each corner — sometimes struts up front and shocks in the rear. Both dampen the spring's movement so your car doesn't keep bouncing after a bump. The difference is structural.
Shocks
A shock absorber is a standalone damper. It bolts between the body and the suspension arm and does one job: control the spring. It does not hold the vehicle up and it isn't part of the steering geometry. Shocks are typically less expensive to replace and don't always require an alignment afterward.
Struts
A strut is a structural part of the suspension. It combines the damper with the coil spring and acts as the upper pivot point for steering. Because the strut sets the wheel's camber and caster, replacing a strut changes the alignment — which is why we always align a vehicle after strut work.
How long do they last?
Most manufacturers suggest inspecting dampers at 50,000 miles and expecting replacement somewhere between 50,000 and 100,000 miles. Birmingham's roads, towing, or a lot of highway miles will shorten that. If your vehicle has more than 75,000 miles on original dampers, it's worth a look.
- Visible fluid leaking down the damper body
- A 'floaty' or unsettled feeling at highway speed
- Longer stopping distances — worn dampers can add 10–20% to braking distance
- Cupped tire wear or a rhythmic tire noise
