shock absorbers

By Nnamdi Ikeh-Akabogu (FRSCN)

Shock absorbers are safety devices often neglected that aid in keeping your tyres in contact with the road at all times.

Springs cushion a vehicle’s ride, but without shock absorbers to dampen the springs’ compression and expansion, a vehicle would keep bouncing after riding over rough streets or sinking into potholes.


Functions of Shocks:

– Shock absorbers keep your car’s tires flat against the surface of the road, providing even pressure so the tread wear remains consistent.


– It absorbs vertical up-and-down impacts and movements for the rear axle and front-end suspension.


– Without shock absorbers, the vehicle’s ride would be noticeably rough and jarring, causing other components to wear much faster than normal…




– Shock Height:

All sides of the vehicle should remain within a few inches of each other if the tyres have the exact pressure and the front end suspension parts have no damage or wear.


Any noticeable deviation in height can indicate a weakened or leaking shock tube.


– Excessive Bouncing:

Excessive bouncing or rebounding when the vehicle rolls over driveway lips or bumps can point to shocks that have lost their dampening effect.


– Leaks:

Any visual leaks around the shock body tube, either at the top or body of the shock, indicate that the seals have worn or split. As a result, there is a loss in hydraulic fluid, and all dampening effect has disappeared.


– Undercarriage Noises:

Loud clanking or knocking noises coming from the undercarriage, when driving over bumps or curves, may indicate a broken shock mount.


– Tyre Wear:

Worn shocks cannot keep the tires firmly planted on the road surface.


– Excess Lean and Suspension Noise:

If the vehicle leans excessively into a tight or gradual turn, this means the shock cannot maintain its height and has lost the ability to carry the frame’s load.
