How is severe leakage in shocks determined?

Severe leakage in shocks is primarily determined by how the vehicle behaves during testing. This approach involves observing the vehicle's performance while it is on the road or during specific testing conditions, such as braking, cornering, or driving over bumps. Symptoms of shock absorber leakage can include excessive bouncing, instability, or poor handling characteristics, all of which will manifest during real-world driving scenarios.

A visual inspection may help identify some leakage, but it is not comprehensive in assessing the overall functionality of the shocks. Checking fluid levels could indicate a problem, but it does not directly assess the performance or the vehicle's response. Measuring shock length could provide some information about their condition but does not effectively indicate whether there is a severe leak or how it impacts the vehicle's operation. Therefore, the behavior of the vehicle during testing is the most reliable method to evaluate severe leakage in shocks.
