Check shock absorbers, (dampers), by pushing down hard on the bodywork at the corners and letting go. The car should rebound once just past the level position and then go back, (one and a half swings).
Any more than this indicates the shock absorbers need replacing.
Listen for knocks from the suspension over poor road surfaces. That could indicate worn bushes, joint and dampers.
Take a note of the cars handling. If it is vague, “floaty” or bouncy, suspect worn dampers.
Check for fluid leakage from the dampers or struts.
Slight weeping is acceptable, anymore is not.
