Everybody who hears a knock over a speed bump assumes shock absorbers. In practice it is far more often a drop link or a bush, both of which are cheaper and quicker than the thing people brace themselves for.

Suspension diagnosis is mostly about when the noise happens rather than what it sounds like.
A light knock over speed bumps at low speed is typically a drop link, the small part joining the anti-roll bar to the suspension. They are inexpensive, quick to change and the first thing we check.
A heavier, duller thud with vague steering points more towards a control arm bush. Worn shocks tend to float and bounce rather than knock, and usually show themselves by the car carrying on moving after a bump.
Uneven tyre wear is the other clue worth reading. Wear on one edge usually means geometry rather than suspension, and replacing parts without correcting alignment just wears the new ones the same way.

Prices are what the job starts at for a car this size; anything the van finds is quoted before it is done. Vehicle and mileage information comes from the DVSA record. Contains public sector information licensed under the Open Government Licence v3.0.
Links, bushes, shocks and springs, yes, on a flat surface with rated stands. Four-wheel alignment cannot, and we will tell you if the job needs it afterwards.
For shocks and springs, yes - they wear as a pair and mismatched ones handle badly. For a drop link or a joint, not necessarily, and we will not pretend otherwise.
Anything involving track rod ends or control arms, yes. We will say so when we quote and point you somewhere with a proper alignment rig.
Usually not immediately, but it is wear and it gets worse. A failed ball joint or a broken spring is a different matter and worth getting looked at quickly.
Suspension work runs mobile across the whole patch, provided the surface is flat enough to work on safely.
