Shocks and Struts
Shocks and struts are important parts of a vehicle’s suspension. Shocks are designed to absorb the impact, while struts support the load of an object such as the chassis of a car. These components are designed to soften the ride.

What is the difference between a shock and a stabilizer?
They both have the same job, the only thing difference is their application. The "shock" dampens continued vibrations from the springs while the "stabilizer" dampens the "shimmy" that the front tires cause.
What would cause a knocking sound at the rear of the van when driving?
the cause of this is probably a bad u joint
A fairly quick and fast way I check struts is I put all my weight down on the hood and give it a push, if your struts are good, it will not allow the car to bounce at all, it will basically absorb the shock and your struts are okay, otherwise your car will bounce excessively and its time to change out you struts. Same procedure for you rears, except they should be coil over shocks and less complex as most cars front suspensions.
you can adjust the spring preload just loosen the nut at the front of the shock but not eather of the mounting bolts its the biggest nut on the shocks to increase the preload using a spanner wrench turn the shock adjusting plate toward the jam nut that's the small mounting nut at the front of the shock and to decrease the preload turn the adjusting plate toward the mounting bolts at the rear of the shock do the same amount of turns to both shocks and then tighten the jam nuts.
How do you replace struts on 2004 expedition?
The struts on a 2004 Ford Expedition are replaced by jacking the vehicle up, removing the wheels, and removing the strut retaining bolts. The old struts can then be removed and new struts put in their place.
99 grand am rattling noise from front end?
It could be your front strut mounts need to be replaced. The rubber inside the strut mounts, wears out. You will hear the noise when u drive over bumps and uneven surfaces. my 2004 grand am se1 4 door ,with the 3.4 v6 engine and automatic transmission, needs the front strut mounts replaced.
What are the symptoms of bad shocks?
what are the symptoms of bad shocks on a car?
When you brake while driving over a "wash board" area in the road, you have a hard time keeping the vehicle under control.
How much does it costs to replace rear shocks on a 2004 ford crown vic P71?
had Midas do mine 273.00
you can do it yourself and save a bunch, the good shocks for a p71 shouldn't cost any more than $65.00 for the pair for the rear.
How often should you replace shocks?
Shocks are oil filled, so if you see oil on the shock body or drips on the ground, replace immieditly. Other than that, it's really hard to say since the way a shock dampens degrades slowly over time and is not noticed. Also, the type of vehicle and the way it's used will also contribute to the shocks life. If you are in doubt, take it to your favorite mechanic and ask his advice.
How the power steering mechanism works?
Power Steering There are a couple of key components in power steering in addition to the rack-and-pinion or recirculating-ball mechanism.
Pump
The hydraulic power for the steering is provided by a rotary-vane pump (see diagram below). This pump is driven by the car's engine via a belt and pulley. It contains a set of retractable vanes that spin inside an oval chamber.
As the vanes spin, they pull hydraulic fluid from the return line at low pressure and force it into the outlet at high pressure. The amount of flow provided by the pump depends on the car's engine speed. The pump must be designed to provide adequate flow when the engine is idling. As a result, the pump moves much more fluid than necessary when the engine is running at faster speeds.
The pump contains a pressure-relief valve to make sure that the pressure does not get too high, especially at high engine speeds when so much fluid is being pumped.
Rotary Valve
A power-steering system should assist the driver only when he is exerting force on the steering wheel (such as when starting a turn). When the driver is not exerting force (such as when driving in a straight line), the system shouldn't provide any assist. The device that senses the force on the steering wheel is called the rotary valve.
The key to the rotary valve is a torsion bar. The torsion bar is a thin rod of metal that twists when torque is applied to it. The top of the bar is connected to the steering wheel, and the bottom of the bar is connected to the pinion or worm gear (which turns the wheels), so the amount of torque in the torsion bar is equal to the amount of torque the driver is using to turn the wheels. The more torque the driver uses to turn the wheels, the more the bar twists.
The input from the steering shaft forms the inner part of a spool-valve assembly. It also connects to the top end of the torsion bar. The bottom of the torsion bar connects to the outer part of the spool valve. The torsion bar also turns the output of the steering gear, connecting to either the pinion gear or the worm gear depending on which type of steering the car has.
As the bar twists, it rotates the inside of the spool valve relative to the outside. Since the inner part of the spool valve is also connected to the steering shaft (and therefore to the steering wheel), the amount of rotation between the inner and outer parts of the spool valve depends on how much torque the driver applies to the steering wheel.
Animation showing what happens inside the rotary valve when you first start to turn the steering wheel
When the steering wheel is not being turned, both hydraulic lines provide the same amount of pressure to the steering gear. But if the spool valve is turned one way or the other, ports open up to provide high-pressure fluid to the appropriate line.
It turns out that this type of power-steering system is pretty inefficient. Let's take a look at some advances we'll see in coming years that will help improve efficiency.
How to fix 'check ride control' alert in 1996 Lincoln continental?
I have a 1996 Lincoln that presented a "Check Ride Control" warning one morning. After driving it for about 10 minutes I could tell it was handling differently. By the time I got to work (50 miles) the front of the car had sunk such that the tires would scrape the inside of the fender when I made a turn. When I left work 10 hours later, the drive home was scary - I probably should have had it towed. The car over-reacted to every bump and each flaw in the road felt like a canyon. After reviewing it for an hour or so, my mechanic said that the air system itself was mechanically ok but the computer was telling it the ride control to empty the cyclinders. He talked to a local dealer and they said they wanted no part of it and that if they were to address the problem I could expect at least $1200 in charges. Thankfully my mechanic isloated a flawed sensor - it cost me $168 for the part and $230 for labor. I was happy to get away with the $398. My understanding is that these systems are really problematic and owners with the time and inclination often replace the air system with a spring suspension system.
Can the air ride suspension be switched to regular shocks on a 1996 Lincoln continental?
Yes!! Aftermarket conversion kits for the older cars with air ride suspensions have become a hot item in recent years because the kits provide a repair solution for vehicles that might otherwise be too expensive to fix. For example, a set of four new OEM air struts and a compressor for a 10-year-old 1994 Lincoln Continental retail for around $3,500. Add in the installation labor, and it adds up to a lot of money to spend on a car that is worth roughly $2,500. The same car could be converted to a regular coil spring suspension for around $500 to $600 in parts, and it would probably be a lifetime repair (no future air leaks, compressor failures or electronic glitches to worry about.) Here is a link to a Monroe kit. http://www.monroe.com/products/mp_detail.asp?cat=Accessories&detail=Conversion%20Kits
How do you replace front struts on a 1991 Chevy Corsica?
get spring compressor or rent 1 loosen front wheels located to big bolts at bottom of strut remove you will need a rubber mallet to hit the large bolts out of strut and hub assembly then remove 19mm bolt and coter pin from outter tie rod dont hit bolt from underneath hit strut w/ hammer til the tie rod loosens the go to under hood locate stut tower remove 3 13mm bolts remove strut apply spring compressor to spring compress the u will need to open end wrenchs to take top bolt off be carefully spring must be securly in compressor and compressed far enough down pull spring off place spring onto new strut tighten down top retaining bolt uncompress spring reverse order of steps when putting back in put top 3 bolts in strut tower first the put back larger hub/strut bolts the 19mm tie rod bolt w/ coter pin you will need a wheel alignment after you done chaning both struts
Does a Ford Focus have shocks?
McPherson struts at the front (shocks and springs together in one unit)
Gas shocks at the rear
How do you replace rear strut on a 1999 Toyota solara?
The 1999 Toyota does not have rear struts. The automobile has rear shocks. Remove the retaining bolts from each end of the shock. Reverse the process to install the new shock.
What is difference between struts 1.3.8 and struts 2.0?
There are many differences between Struts 1.3 and Struts 2.0-
1)Action Class-
In Struts 1.3, Action Classes needs to extend an abstract base class. But in Struts 2.0, Action classes needs to implement an Action interface.
2)Thread-Safety-
In Struts 1.3, actions are singletons and thread-safe.
In Struts 2.0, action objects are instantiated for each request.
3)In Struts 1.3, actions must share same lifecycle.
In Struts 2.0, every action has different lifecycle.
4)In Struts 1.3, servlet action have dependencies on servlet API.
In Struts 2.0, these dependencies have been removed.
5)Struts 1.3 uses Action Forms to take the input.
Struts 2.0 use Action Properties for taking inputs.
As Struts 2.0 is improved version of Struts 1.3, so there are uncountable similarities between them. All the basic features are same in both.
How do you change the struts on a 2002 Chevy Prizm?
You need a special strut spring compression tool. Very very difficult to do it by yourself, unless you have this tool. Getting the struts off is not too hard, putting the new strut in is the hard part.
What is causing my front end to make noise over bumps?
it could be your roll cage or ball joint might have to much movement or play and might need replacing.
