I get alot of questions about Bushing. (Alot of questions.) Half of them involve what they are. They are literally in every part of the car. They are esentially a connector between two pieces of metal. Most have some sort of rubber for impact absorbption. This article has to do with the Steering Rack bushings.

The rack and pinion steering unit goes the width of the car and thus has to mount somewhere. Usually there are two to three mount point and all have a bushing. The steering rack bushing can be a rubber grommet in the mount or a just a piece of rubber that goes inside a strap mount. These should always be inspected when replacing a rack. Worn or damanged bushings will cause too much movement and ultimately damage the steering gear.

The rule of thumb is that if they are pressed in, meaning they are permanent and do not get removed then you are good. If they are inserts and removeable you should change them.
