Shock absorbers, or shocks, are dampeners which convert the kinetec energy in springs into heat engergy so it may be dissipated. Without shocks, a vehicle would bounce uncontrollably whenever the springs absorbed that kinetic energy from imperfections in the road.
Shock absorbers take a lot of punishment and will eventually wear out. Because of this, they should be monitored regularly and replaced when signs of wear become obvious. Loud noises when hitting bumps, rough rides, constant "bouncing" after hitting a bump, leaks down the side of the shocks and uneven tire wear are some of the signs.
It is best to leave this repair to a professional as job specific tools and knowledge are required!
