How to Replace a Sway Bar Link

A sway bar link is used to control side to side movement or the amount of lean a vehicle is subject to when entering and driving through a corner.

How Does It Work?

A sway bar and link system uses a thick metal bar that spans the suspension at either the front or rear of the vehicle and is bolted to the frame using rubber bushings. At each end of the bar are links which are bolted to the upper or lower control arm. When the vehicle is at a stand still or being driven in a straight line the sway bar is at idle and not used, but when a curve is introduced the sway bar jumps into action by resisting the lean force and keeping the vehicle flat which improves the vehicle handling characteristics.

What Goes Wrong?

A sway bar rarely breaks, problems arise when the rubber bushings that connect the bar to the frame, and at either end where it attaches to the suspension components wear out and fall apart allowing the metal of the bar or link to contact the frame or control arm which generates unwanted noises and diminishes the sway bar's performance.

What's the Cost?

A sway bar link or main bushing is not difficult to replace and should take between .8 and 1.0 hours for both sides with the cost of the parts ranging from $45.00 to $65.00 for the link kits, and about $10.00 for the main bar bushing set. If exact times or procedures are needed you can ask our experts to supply you with the information (free), or consult an online resource such as AllData DIY (pay) but this guide and video will be sufficient in most cases, the design of the links may vary slightly.

Lets Jump In!

In most cases the car will need to be lifted and supported using jack stands, inspect the rubber bushings at each end and at both mounting points on the frame.

Here we are replacing the link bushings using a kit which is easily obtained, begin by removing the link through-bolt by holding the top nut and turning the bolt head at the bottom.

Once both links have been removed match the new link kit to the old parts to ensure a proper installation.

Assemble the new link kit in the same configuration inserting the through bolt with the washer and bottom bushing starting at the lower control arm.

Complete the installation by stacking the washer on top of the spacer while inserting the bushings, then tighten the nut to spec, in this case it is 23 foot pounds of torque, it is best to replace both sides at the same time.
