Sway Bar Link Replacement
Time: 2017-03-29
Any problem with your car’s suspension can quickly turn into a major safety problem. It’s not a good idea to use the “I’ll wait until something really breaks” approach.
Symptoms of a broken sway bar link include porpoising, wandering steering and when it gets really bad, a clunking sound. Replacing a worn or broken sway bar mount is not as terrifying a job as you may think. If you have access to some simple mechanic’s tools you are very capable of getting this one done.
Before beginning any car repair that involves working with one or more of the wheels off, you need to perform a mental safety check. Accidents underneath a fallen vehicle can be unforgiving.
Support the vehicle safely on a jack stand and remove the wheel on the offending side. If you’re replacing both sway bar links, you can support the entire front of the vehicle on jack stands, which will make the job go faster as you will be able to work on both sides at once. With the vehicle in the air and the wheel off, you have access to the sway bar link. In many cases the mount will actually be broken, as it was on this vehicle. The studs that hold the link to its threaded mount sheared off, leaving the sway bar to bounce all over freely. 
Next, remove the lower sway bar mount bolt. You need a properly sized hex wrench (Allen wrench) and an open end wrench. The hex wrench will be used to lock the bolt in place while you remove the nut from the back of the bolt. It’s a little tricky getting your hands on everything you need to hold onto, but it is there. Remove the upper bolt. Like the lower bolt that you just removed, the upper bolt is held in place by a nut and a hex wrench driven bolt. Use the hex wrench to hold the bolt in place while you use your open end wrench to remove the bolt. Try to note (or even better, take a digital picture) the position of the part before taking a part out.
Hold the bolt in place with the hex wrench while you remove the nut.
With the old sway bar link removed and any parts you’ll be reusing cleaned up, you are ready to install the new part. As the old automotive saying goes, installation is the reverse of removal. Lock nuts should never be reused so you need get some new ones. Tighten everything up nice and snug, put your wheel back on, and you can prepare for a much smoother trip.
