The mechanical system that attaches a vehicle's chassis to its wheels, managing the dynamic forces of driving. It consists of springs to support the vehicle's weight and absorb bumps, shock absorbers to dampen the spring oscillations, and control arms or linkages to maintain precise wheel alignment. A properly tuned suspension maximizes tire contact patch with the road while isolating the cabin from harsh impacts.
We need to inspect the front suspension because the customer complains of a clunking noise over speed bumps.
Suspension components usually wear out in pairs. If the left strut is leaking and needs replacement, the right one is likely at the end of its life too.
