how do shock absorbers work?
432197
Shock absorbers work by taking the kinetic energy (movement) of your suspension and converting it to thermal energy (heat) that is then dissipated into the atmosphere through the mechanism of heat exchange. But it's nowhere near as complicated as it may sound. As mentioned, shock absorbers are basically oil pumps.

Rather, the shock absorber absorbs energy. A vehicle without shocks would keep bouncing up and down for a while after every bump; the shock absorbs the energy of the bouncing. Unfortunately, shocks and struts can break or wear out. ... Smaller parts inside the shock may wear out over time or due to an impact.

If you need to replace your car's shock absorbers but don't want to pay an expensive mechanic's fee, you can do so on your own with a little effort. Shocks are essential to a car's performance, giving it a smooth and even ride. Over time, however, the vehicle's suspensions become worn out.

It's not necessary, but it's usually recommended to replace them in pairs, for example, both front struts or both rear shocks. This is because a new shock absorber will absorb road bumps better than the old one.

Shocks & Struts. BMW shocks & struts provide the damping control for your BMW's springs. Shocks and struts are where the suspension-control magic of your BMW comes from.

This airbag works as an inflatable seatbelt that inflates upon frontal impact from another vehicle. ... Activation of automotive airbags is triggered by crash sensors (also known as impact sensors) that work to detect frontal impact and trigger a control unit that deploys the airbag to cushion the passenger.

Shock Absorbers. ... Shock absorbers slow down and reduce the magnitude of vibratory motions by turning the kinetic energy of your bouncing suspension into heat energy that can be dissipated through hydraulic fluid. In physics, this is known as damping, which is why some people refer to shock absorbers as dampers.

The shock absorbers do wear out over time, and need to be replaced to ensure the handling of your vehicle is as safe as possible. Front Shock Absorber replacement can cost between $250 - $700 and up, depending on the type of shock absorbers and if other components need to be removed to allow access.

For us, this rear shock absorber by Bilstein is the best of the bunch. Thanks to its tough and durable design, this versatile shock is suitable for a wide range of vehicles - from trucks, to SUVs, to Jeeps. Its monotube construction offers excellent fade-free performance, keeping you on the road for longer.

Unfortunately, shocks and struts can break or wear out. The three things that are most likely to go wrong with a shock are: The seals can become brittle or torn, allowing fluid to leak out; after some fluid (about ten percent of the total) is lost the shock loses its ability to absorb energy.

Characteristics. Coilover and shocks are both used in vehicles to manage the suspension springs, which bounce a vehicle up and down as it runs over bumps and holes. Coilover arrangements include shocks in them; coilovers are coil springs that are wrapped around a shock absorber.

How much does a Shock Absorber Replacement cost? Standard Shocks: A standard Shock Absorber Replacement will cost $70.

The jacket works by activating its sensors 800 times a second to monitor their wearer. When they detect an accident, the jacket will inflate about two inches in the areas where an airbag is present, with the intention of protecting the wearer's collar bone, chest, and back, as well as keeping strain off of their neck.

A strut is the shock absorber built into one unit with the coil spring (in the photo). Any car has four struts/shock absorbers; one at each wheel.

Shock absorbing materials may also be called shock absorbing polymers, visco-elastic polymers, visco polymers or simply polymers. There are many other shock absorbent materials available like rubber, neoprene, silicone, etc.

Typical costs: Shock absorbers or struts can cost $25-$350 or more each, depending on the make and model of vehicle and the quality of the part. Although it could cost as much as $1,400 for a set of four, most do-it-yourselfers spend an average of $150-$250 to replace four shocks/struts.

In general, a shock absorber should last at least 50,000 miles before you need to have it replaced. However, the real determining factor is where you drive and how you drive. For instance, if you do a lot of off-road driving, or spend a lot of time on dirt roads, your shocks will wear out much more quickly.
