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.

Difference between struts 1.2 and struts 2.0?
What is the Difference Between Struts1 and Struts2
Struts2 is more powerful framework as compared to struts1. The table given below describes some differences between struts1 and struts2
S.R. No
Struts1
Struts2
1
Action class in struts1 extends the abstract base class. The problem with struts1 is that it uses the abstract classes rather than interfaces.
An Action class implements an Action interface, along with other interfaces use optional and custom services. Struts 2 provides a base ActionSupport class that implements commonly used interfaces. Although an Action interface is notnecessary, any POJO object along with an execute signature can be used as an Struts 2 Action object.
2
In Struts1 Actions are dependent on the servlet API because HttpServletRequest and HttpServletResponse is passed to the execute method when an Action is invoked.
Struts 2 Actions are not coupled to a container. Most often the servlet contexts are represented as simple Maps, allowing Actions to be tested in isolation. Struts 2 Actions can still access the original request and response, if required. However, other architectural elements reduce or eliminate the need to access the HttpServetRequest or HttpServletResponse directly.
3
Struts 1 recieves an input by creating an ActionForm object. Like the action classes, all ActionForms class must extend a ActionForm base class. Other JavaBeans classes cannot be used as ActionForms, while developers create redundant classes to receive the input. DynaBeans is the best alternative to create the conventional ActionForm classes.
Struts 2 uses Action properties as input properties, eliminating the need for a second input object. Input properties may be rich object types which may have their own properties. The Action properties can be accessed from the web page via the taglibs. Struts 2 also supports the ActionForm pattern, as well as POJO form objects and POJO Actions. Rich object types, including business or domain objects, can be used as input/output objects. The ModelDriven feature simplifies taglb references to POJO input objects
4
Struts 1 supports separate Request Processors (lifecycles) for each module, but all the Actions in the module must share the same lifecycle.
Struts 2 supports creating different lifecycles on a per Action basis via Interceptor Stacks. Custom stacks can be created and used with different Actions, as needed.
5
In Struts1 Actions are singletons therefore they must be thread-safe because only one instance of a class handles all the requests for that Action. The singleton strategy restricts to Struts 1 Actions and requires extra care to make the action resources thread safe or synchronized while developing an application.
In Struts 2 doesn't have thread-safety issues as Action objects are instantiated for each request. A servlet container generates many throw-away objects per request, and one more object does not impose a performance penalty or impact garbage collection
6
Struts1 application has a major problem while testing the application because the execute method exposes the Servlet API. Struts TestCase provides a set of mock object for Struts 1.
Struts 2 Actions can be tested by instantiating the Action, setting properties, and invoking methods. Dependency Injection support also makes testing simpler.
7
Struts1 integrates with JSTL, so it uses the JSTL EL. The EL has basic object graph traversal, but relatively weak collection and indexed property support.
Struts 2 can use JSTL, but it also supports a more powerful and flexible expression language called "Object Graph Notation Language" (OGNL).
8
Struts 1 ActionForm properties are usually all Strings. Struts 1 uses Commons-Beanutils for type conversion. Converters are per-class, and not configurable per instance.
Struts 2 uses OGNL for type conversion and converters to convert Basic and common object types and primitives as well.
9
Struts 1 uses manual validation that is done via a validate method on the ActionForm, or by using an extension to the Commons Validator. Classes can have different validation contexts for the same class, while chaining to validations on sub-objects is not allowed.
Struts 2 allows manual validation that is done by using the validate method and the XWork Validation framework. The Xwork Validation Framework allows chaining of validations into sub-properties using the validations defined for the properties class type and the validation context
10
Struts 1 binds objects into the page context by using the standard JSP mechanism
Struts 2 uses a ValueStack technology to make the values accessible to the taglibs without coupling the view to the object to which it is rendering. The ValueStack strategy enables us to reuse views across a range of types, having same property name but different property types.
How do you replace rear shocks?
What type of vehicle?

If you have coil springs in the rear, you need to have two jacks. One will jack up the car up to take the tire off and be able to get to the shocks. The second jack will be used to stabilize the bottom of the coil pan so it doesn't drop down once you remove the shock and it will stay in perfect position to replace the new shock.
1. Your car may have had previous frame and/or unibody damage. 2. Did you have a 2-wheel or 4-wheel alignment done? If it was only a 2-wheel alignment, the rear axle(s) may not have been properly aligned with the front ones, so that your vehicle may "dog-track" with rear end swaying to one side or the other after you hit bumps or uneven road. 3. Your front or rear shock absorbers may be worn out. 4. Make sure that the new tires are the correct size as recommended by the manufacturer of your car.
if your dealing with the stock unit, the answer is real simple you don't its welded and your new stablizer should come with a new one.
How do you replace the rear struts on a 1995 Mercury Tracer?
jack up car, remove wheel, may need a pry bar, remove 2 bottom bolts at bottom of strut. go into trunk area & find top of strut mount and remove the 3 or 4 nuts securing the top. push down hub assembly & pry outward, pull strut down and out. installation is opposite of removal.
Has anyone tried the Monroe quick strut assembly on their vehicle?
if you have a Saturn S Series (Mon171924) ,Stay away from them, Both front Struts will squeak and drive you CRAZY Hopefully Monroe will have solution for this problem.
It will fit, just press the lower A-frame further down than what you are doing now. I used an anchor bolt to draw it down. It is difficult, but once done, no problem. The next answer might be correct if you are talking about actually changing the entire strut assembly yourself, i.e. take the spring off. Don't do that! However, if you are only going to replace the unit as an assembly then there is no problem. This Is Dangerous, You Need A Special Press To Change Struts.Buy Them Where They Also Change Them, Or Better Let An Alingment Take Care Of This For You. Rotate Tires & Get An Alignment While You Are There Also.
How to replace rear shock absorbers on 1994 grand marquis?
You will need 2 jacks. 1. Jack up the rear body on the side you are working on and remove the wheel. 2. Place a jack underneath the rear axle to support it. (you will find a screw type jack helpful - I needed to raise and lower the axle to get pressure on the rod and to get the nut on. 3. Get a wrench (14mm normally) that will be long enough to reach the shock nut between the frame and the body. 4. With the wrench attached to the nut, twist the boot of the shock counterclockwise. Hold the wrench so the nut is broken loose. 5. If the boot just spins, you will have to cut a portion of it off to access the push rod. You will then need channel locks or vise grips to twist it. (Note, a ratcheting wrench is helpful, but not necessary.) 6. Once you get the top off, the rest is easy. 7. I found that a little masking tape to hold the bushing and washer into position when reinstalling the new shock handy. 8 Good luck, wish I could say the job is fun, but to be honest, its pretty brutal. Be sure you have a lot of space where you can throw tools. :-)
Can you drive with a worn tie-rod?
Not a good idea. Just think what would happen if it broke while you were driving.

What is the purpose of a damper in a macpherson strut?
To absorb the shock of going over a pot hole, save space and to stop the car bouncing up and down when bounced.
Is it tough to replace the rear struts on a 1999 Hyundai Accent?
Yes, and potentially dangerous. Better to have a shop do it if you're not familiar with cars (you'll need a spring compressor if just replacing the shock, but an impact wrench is a must whether your replacing the shock or the whole strut). However, the service manuals for Hyundai can be found on line at http://www.hmaservice.com/webtech/ Click on the "shop" tab, choose your car and find the information you are looking for.

How do you change struts on a 2001 Jetta GLX VR6?
For front struts: Jack up your car and secure it on jackstands and get underneath the car and look to see where the lower part of the stut bolts behind the rotor. take out that bolt and then go to the top of the strut tower (in engine bay) and take off those nuts( its best to use an impact wrench to take these on and off. Or go buy the special strut tool. After that bolt is out you should be able to maneuver the strut out of place. Repeat that for the other side.
For Rear Struts: Make sure your cars jacked up in the back and secured on jackstands. Then pop your trunk and you will have to move the carpet out of the way to get at the rear stut towers. Do the same thing as in the first by going under the car and taking out that bolt in the strut mount. Then go to the top and take out that bolt for the top strut mount. Maneuver strut out of place. Repeat for other side as well.
For removing springs from struts: USE EXTREME CAUTION WHEN REMOVING SPRINGS!!!!!! You will need to either go to your local auto parts store and rent a spring compressor. Or what i would recommend is take the whole strut and spring assembly to a local auto garage and have them remove them since they are experienced. Have them put your springs on your new struts as well while you are there. it shouldn't cost much money and you will be sure it was done correctly.
Installation is the reverse of Removal. Mkae sure you torque the bolts to the specified amount. Im not sure what it is, maybe like 35-40 ft/lbs. don't quote me on that though.
- I am not responsible for anything you do regarding this post. This is what i did to replace my springs. If anything goes wrong while you are attempting to do this its not my fault.***
Is there a difference between rear and front struts on a 95 mercury sable?
my understanding was that struts typically are on the front of a vehicle while
shocks are on the back. yes there should be a difference, far more weight in
the front of a sable than the back, even with the trunk loaded. my guess is that
they are very different parts.
How do you replace the front and rear struts on a 1997 Chevrolet Cavalier?
The question you ask is too involved for a proper answer. You may want to go to a car parts store, or book store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
How do you replace Chrysler Concorde trunk struts?
It's pretty simple to replace these truck struts. First, you find the right ones online. Make sure they say they will fit your year Concorde. Don't get the trunk struts for the Dodge Stratus or another car as they will not be long enough. Always replace them in pairs. They will cost about $30 for the pair.
Replacing them you only need a screwdriver and maybe a rubber mallet (I used the palm of my hand). You take the caps off with the screwdriver, and take the worn struts off and recycle them. To get them off you use the mallet or your hand. Hit straight and be careful.
Then, you snap the new ones on the same way. Be careful as the new ones will be very strong and your truck will pop up really fast. This could damage your truck, so use two hands to open it, and let it raise up gently.

How do you replace shocks and struts on a Volvo S60?
To replace the shocks and struts on a Volvo S60, start by safely lifting the vehicle and removing the wheels for access. Then, detach the old strut assembly by removing the bolts connecting it to the knuckle and the top mount under the hood. Install the new struts by reversing the removal process, ensuring all bolts are tightened to the manufacturer’s specifications. Finally, reassemble the wheels, lower the vehicle, and perform a wheel alignment to ensure proper handling.
Shocks should be changed when you notice a significant drop in ride quality, excessive bouncing, or uneven tire wear, as these signs indicate that the shocks may no longer be effectively dampening the vehicle's movements. Additionally, if you hear unusual noises such as clunking or knocking when driving over bumps, it's a good indicator that the shocks are failing. Regular inspections, typically every 50,000 miles or during routine maintenance, can help determine their condition as well. If in doubt, consult a mechanic for a professional assessment.
How do you change rear coil springs on a 98 lesabre?
To change the rear coil springs on a 1998 Buick LeSabre, start by safely lifting the vehicle and securing it on jack stands. Remove the rear wheels, then disconnect the shock absorbers and lower control arms to relieve tension on the springs. Use a spring compressor to safely compress the old springs, then remove them from the vehicle. Install the new springs by reversing the process, ensuring everything is properly torqued and reassembled before lowering the vehicle.
