What does an anti-roll bar do?

A clunking noise can be heard particularly as I drive over speed bumps, so I took it to a car repair centre to see what it was.


They said it's the Anti-Roll bar and that the 'bushels' have come loose.


My dad wants to see if he can repair this himself, is this possible?|||As a car goes around a corner, it will tend to sway outwards. The weight shifts to the outer wheels relative to the turn which causes that side to lower while the inside will tend to raise up. This causes a difference in position relative to each side.





The bar you speak of is connected to both the lower control arms on either side which itself connects the wheels to the frame. The bar will resist the difference of vertical position of the right and left sides. This results in less sway when going around corners. For dynamic stability, it is very important to sway as little as possible yet not be so rigid that the inside wheels lose grip or even come off the ground. The manufacturer designed the parts to give good performance. If you lose the sway bars, you will lose the stability. The shocks help with stability as well, but they may be worn as well. If you turn back and forth a few times quickly, it is possible to flip the car without sway bars in tact and aging shocks.





This repair isn't hard. It's a matter of replacing a couple parts. The key is to inspect other suspension parts to ensure that they have not been damaged or are worn out. Turn the wheel far over and take a look. Are there any parts that are cracked, rusted through, broken or sheared off? Usually a serious problem will be obvious to even an untrained eye.|||Called a sway bar the antiroll bar is connected to suspension on both sides of the car's suspension. Yes if Dad can get the bushings and end link parts the sway bar is owner serviceable with minium sockets vice grips and wrenches. However some cars like my 2006 GTO the sway bar is burried on top of the suspension cross member and requires lots more work. Good luck|||It is called a anti-roll or sway bar. What has come loose are the "bushings". These are rubber mounts that fasten the bar to the vehicle. What a sway bar does is keep the frame and body of the vehicle centered over the suspension during cornering so the center of gravity does not shift too far over and cause your vehicle to roll over. It is a straight foward replacement, not to technical. Some vehicles are simpler than others.|||an anti roll bar keeps you from rolling over








duhh|||Anti roll bar is another name for a sway bar. It helps to reduce body lean or roll in a turn..





Like you drive around a curve, and you notice the car leans to what ever side the curve turns too.





It's very fix-able by your Dad. The bushings is what's worn or loose. Theres 2 sets of bushings. The sway bar bracket bushings and the end links.





The bracket bushings goes around the sway bar and a bracket goes over it and mounts to the frame/chassis of car.





The end links are a long bolt, and a few round rubber bushings, that goes through a hole in the end of the sway bar and bolts to the A arms (controll arms) of the suspension
