Sooner or later the bushing will need to be replaced, either the bolt could brake or the bushing becomes damaged.
You will need something like this. These are universal sway bar end bushings and can be picked up at most auto parts stores. These cost $7.99 each
The stabilizer bar is located on the lower A frame on the back side. Here is a broken bolt.
To remove the bushing bolt you will need to jack up the car, install jack stands, and remove the tire. From under the A frame you will find the bolt head. This is a 13mm bolt.
You will need to hold the bushing with a channel locks. The bolt will be rusted bad, will most likely brake, and will fight all the way out. You might end up cutting the bolt off.
Remove both ends of the bolt with all the rubber bushings.
Clean up the area of any rust or dirt.
Now that you have removed the old bushing it'* time to install the new set. Here are the parts in each kit.
The is the order in which the parts go together.
Start with the bolt, one washer, and one rubber bushing. This will go in from under the A frame
If the old bushing broke, you will need to draw the sway bar down about half a inch or so. Use a large C clamp. You do not need to use a lot of pressure. To much and you risk the clamp popping loose and you could be injured. If your removing the old bushing you can use the C clamp to hold teh sway bar in place.
Get all your parts lined up and in place like this and put the nut on top. Put the curved end on top. This is a locking nut.
Now draw in the bolt until it feels tight, but not to tight. You will then set your torque wrench to 13 foot pounds, or 156 inch pounds. This will take some time to get this to the correct torque. The bushings need to settle, so check it several times.
It should look like this when done.
