Understand your Car

Your car’s suspension is composed of a system of shock absorbers, springs and linkages that connects the vehicle’s body to its wheels. It contributes to the car’s braking and handling.

There are two general kinds of suspension systems: independent and dependent. It refers to the opposite wheel’s ability to move against or towards of each other.

Independent suspensions have several subtypes, including double wishbones, multiple-links and McPherson struts. Independent suspensions are said to be more comfortable and capable in road holding on varied surfaces. It allows the wheels to rise and fall on their own without affecting the opposite wheel. Some suspension devises the link the wheels are still classified as independent, an example of this is sway bars.

Dependent suspensions include types like rigid axles and torsion-beams. These are more versatile and are also cheaper. It normally has a beam or a live axle that holds wheels parallel to each other and perpendicular to the atv axle. When the camber of one wheel changes, the camber of the opposite wheel follows in the same direction. Dependent suspensions are most common on vehicles that carry large loads.

There is a third type, which is semi-independent. Here, the motion of one wheel affects the position of the others, but they are not rigidly attached to each other. A twist-beam rear suspension is an example of this system.

Atv Buyer's Guide: 15 Things To Check Before You Buy

Are you in the market for an All-Terrain Vehicle (ATV)? An ATV can provide you with years of fun outdoors, but if you don't know what to look for, you're in for a giant headache. This ATV buyer's guide will provide you with 15 things to check before you buy. Whether you're a seasoned expert or just getting started, the following will be beneficial to you.

When it comes to shopping for an ATV, there are a ton of things you should keep in mind so you can get the best possible machine for your dollar. Here is a list of 15 things to look for when shopping for an ATV or quad.

1. Take it for a ride. It is an ALL Terrain Vehicle, right? So, you should pretty much be able to take it for a test drive just about anywhere. If the seller has a problem with you taking it out for a spin, there's probably something wrong with it.

2. Check the head lights, tail lights, engine shut off switch and key switch. All should be in perfect working order.

3. Check the hand, foot and parking brakes. Do they operate smoothly or stick? Be sure to check for damaged or cracked cables.

4. Move the handlebars back and forth. This will help you identify worn tie rod ends.

5. Remove the seat and take the air box lid off. A clean air box and filter is a good sign - if there's water in it, the engine could be damaged.

6. Check for worn out tires or tires full of plugs. If they are worn or plugged a lot, it's not necessarily a problem but it could get you a discount on the price.

7. Check the exhaust to make sure that the spark arrestor is still there. Almost every state and national forest requires that you have one. If it has been removed, make sure they replace it before you buy.

8. Check the engine oil to make sure it's clean and at an optimum level. This should give you a quick idea of how well the engine has been maintained by the current or previous owner.

9. Check the gas tank for rust (use a flashlight). Yes, a gas tank can rush, and rust can cause problems for the carburetor.

10. Now, pick up the front of the quad and stand it up on the rear grab bar so you can check the undercarriage for damage.

11. While it's in this position, look at the frame. Make sure it isn't bent, cracked or rusted.

12. Inspect the CV joint boots (4x4). If there are any cracks or tears, they could contain water or dirt and that's costly to repair.

13. If it's possible, remove the front and rear differential inspection plugs (4x4). If the lube looks dirty, the oil is probably contaminated and there could be bearing damage.

14. Look closely at the front or rear sprockets. Each point should be uniform. If they are worn more on one side or have a hooked appearance, a new chain and sprocket set is in order.

15. Try to move each front wheel in and out from top to bottom and side to side to check for worn wheel bearings and ball joints. Do the same for the rear.
As always, the rule is simple: Buyer Beware! If a deal sounds too good to be true, it probably is. Good luck!
