A workshop told me that the front left suspension of my car was leaking and that I should replace it. It was recommended that I replace all four. What does a suspension leak mean and why do I have to replace all four?
Suspension refers to several parts that include rubber bushes, link arms, springs and dampers. The only component that can leak is the damper (also referred to as a shock absorber) because it contains oil and, in many cars, gas too.
Due to wear and tear, the oil or gas could leak and the ride will become harsher as the car will bounce on its springs every time it rides over bumps.
It is advisable to change dampers in pairs (front or rear pair). But if your car is more than five years old or has run more than 80,000km, it might be a good idea to change all four.
