A shock absorber is a mechanical device designed to smooth out or damp shock impulse, and dissipate kinetic energy. It is a type of dashpot. The shock absorber's function is to absorb or dissipate energy. One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most dashpots, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of dashpots, such as electromagnetic types, the dissipated energy can be stored and used later. In general terms, shock absorbers help cushion vehicles on uneven roads.
1.Loosen the lug nuts of one wheel using a lug nut wrench. Do not completely remove the lug nuts at this time.
7.Continue these steps until all four shocks have been replaced.
In short a shock absorber works to stop the unpleasant oscillations that occur on cars, trains, buses and other vehicles.
Shock absorbers are used to guarantee a smooth ride, even as you drive over bumpy terrain. After driving on a set of shocks for a while, they may become worn and need to be replaced. As with most automotive maintenance issues, you may be able to replace shock absorbers on your own.
The shock absorbers in your car should be replaced every 75,000 miles. It is important to replace worn shock absorbers to ensure a smooth-riding vehicle. Shock absorbers attach to the axle of the vehicle and dampen the the effects of the bumps the car travels over. Aftermarket shock absorbers can be purchased at any auto-parts store that will fit your particular vehicle. Avoid the cost of taking your car to a mechanic by replacing the car shock absorber yourself.
1.Loosen the lug nuts of one wheel using a lug nut wrench. Do not completely remove the lug nuts at this time.
2. Place a hydraulic jack under the vehicle. Refer to your owner's manual for proper jack positioning. Lift the vehicle with the jack enough to lift the tire from the ground.
3. Locate the bolts securing the shock into position. There will be bolts on the top and bottom of the shock. Lubricate these bolts with penetrating fluid to remove the surface rust.
4.Remove the bolts using a socket and ratchet, turning them in a counterclockwise direction. Keep the bolts, as they will be used to secure the new shocks. Remove the shock from the vehicle.
5. Replace the new shock absorber into position. Install the bolts and tighten them using a ratchet and socket.
6.Re-install the tire and lug nuts. Lower the vehicle to the ground and remove the hydraulic jack.
7.Continue these steps until all four shocks have been replaced.
In short a shock absorber works to stop the unpleasant oscillations that occur on cars, trains, buses and other vehicles.
