Difficult handling, a rough ride, vibration and poor performance are symptoms you can feel. They almost always indicate a problem. Difficulty starting the engine. Poor transmission performance may come from actual component failure or a simple disconnected hose or plugged filter. The vehicle pulls to one side when the brakes are applied.
Misaligned front wheels and/or worn steering components, such as the idler or ball joint, can cause wandering or difficulty steering in a straight line The "check engine" light on the instrument panel is lit. Delayed or no response when shifting from neutral to drive or reverse. The brake pedal sinks to the floor when pressure is maintained.
Pulling - the vehicle's tendency to steer to the left or right - can be caused by something as routine as under-inflated tires, or as serious as a damaged or misaligned front end. Rough idling or stalling. Failure to shift during normal acceleration. You hear or feel scraping or grinding during braking.
Worn shock absorbers or other suspension components - or improper tire inflation - can contribute to poor cornering. Poor acceleration / Poor fuel economy. Slippage during acceleration. The engine speeds up, but the vehicle does not respond. The "brake" light on the instrument panel is lit.
Engine
While there is no hard and fast rule about when to replace shock absorbers or struts, try this test: bounce the vehicle up and down hard at each wheel and then let go. See how many times the vehicle bounces. Weak shocks will allow the vehicle to bounce twice or more. Excessive oil use (more than one quart between changes). Abrupt or hard shifts between gears.  

Springs do not normally wear out and do not need replacement unless one corner of the vehicle is lower than the others. Overloading your vehicle can damage the springs.

Engine continues running after the key is removed.  
Balance tires properly. An unbalanced or improperly balanced tire causes a vehicle to vibrate and may wear steering and suspension components prematurely.
