Frank, you haven't said what make or model your car is.
However, have a look on the following link - it will take you to Youtube:
how to replace anti roll bar bushes Google Search

It's not a particularly difficult job. It entails loosening the drop-links/tie bars that connect to the torsion bar - the anti roll bar, then loosening the bolts holding the anti roll bar in place.

Just be aware that the anti roll bar is in effect a 'spring' and is under tension. Loosen the retaining bolts gradually, slowly.

replacing the bushes is straight forward. Once you have removed the anti roll bar just lever the old rubber bushes out with a screwdriver and push the new ones into place .. then reassemble everything.

In the most general of terms you would do the job in a couple of hours

anti-roll bar bushes, could be the problem get a big screw driver and lever the anti roll bar see if you have movement

hi its just spring activated, just follow instructions below to reset the roll bar1. Raise rear headrest to its highest possition
2. With a screwdriver, remove the plastic cover that is located under the headrest between the roll-bar.
3. Reach down into the opening to locate the metal tab that has locked the spring loaded roll-bar into place.
4. Simultaniously push the tab in (towards the front of the car ) while pushing downward on the top of the exposed roll-bar to compress the springs. Push all the way down until the bar locks into place.
hope this helps please comment and rate thanks

Sway bar, also called anti-sway bar, stabilizer bar, roll bar, anti-roll bar, or ARB.

I have 1997 mercedes benz sl500 after changing my battery, my roll bars will not go down. how do I get my roll bar back down?

Hi , there is a special tool required to release the mechanism catch so you can push the roll over protection bars back to the opperation position , if you have a local dealer to you, they should be able to reset them at little or no cost , hope this helps , regards mark .

This system is designed to release the roll bar from the actuating rams due to input from the axle(suspension travel) sensors in the rear of your vehicle. More than likely your roll bar system released the bar and it sprung upwards. You have to hold the roll bar switch in the up position until the rams travel up and lock back into the bar. Once they lock back in the system will be operational again.

I have a 2005 CLK 320. Roll bars deployed on a bump with the top up. Here's how to fix it: There is a reset port about 12 in below each headrest. The port is hard to find, but you can actually glimpse it with good light and/or a flashlight and some head/neck contortion. When facing forward the port is on the left side of each headrest. The port is oval in shape, about 4mm x 8mm, positioned about 10 mm forward of the support post and about 5mm to its left. Essentially, its an oval hole in black sheet metal. Mercedes mentions an allen key tool included with the car, but you can use a very long screwdriver or, preferably, a metal shishkabob barbecue skewer (by far the best) to reset the mechanism. Slide the tool (skewer, screw driver or allen key) straight down along the side of the headreast and then very carefully angle the tip forward and to the left (of car) to go into the port. Again, you can see this if you try. Push down on the spring under the port and hold down while you push down (Hard) on the headrest to its full reset position. Then remove the tool. Voila!

Before the reset, the top would not go down. After the reset, no problemo. Dennis
