1997-2013 Rear Anti-roll / Sway Bar Link Replacement
By Chris Petris
When we had a chance to look under the first C5 in 1997 it was hard to believe a performance vehicle would have a plastic anti-roll (sway bar) link. To make things difficult lock nuts were used to hold the links stud into the control arms. That meant when someone removed the end link chances are they would rip the joints seal because they did not hold onto the stud during removal. The original plastic sway bar end links flexed under hard cornering making the anti-roll bar less beneficial. Of course a hard driving Corvette owner might break one or more on a track day. By 2002 GM finally dropped the plastic pieces replacing them with an aluminum anti-roll bar end link. One of the few things that did occur positive is the same end link is used from 1997-2013 so you can easily find and replace the weak original 1997-2001 links. If someone was not being careful and tore the end link seal during suspension service you may need to replace one or more on your 2002-2013 Corvette.
Corvette Central has the anti-roll bar end link you need in stock form or heavy-duty performance Heim joint style end links. The installation is simple and does not require much time or many tools to complete. We often replace the end links when replacing shocks making a simple job even easier. The most important thing to remember when replacing the end links; the wheels should be hanging free on the front or rear. If one wheel is hanging free and the other wheel is loaded the end link will also be loaded making it difficult to remove and possibly dangerous. This is not something you can do by jacking up one side of the Corvette at a time; it must be done with the front or rear jacked up. The following photos will show you how it’s done.
An 18mm wrench is used to turn the nut while a T40 Torx bit holds the stud. Of course you can spin the stud on the old pieces for removal.
You can see the difference in this original 1999 anti-roll bar end link which has some distortion from age. The aluminum end links available from Corvette Central are stout pieces with new rubber seals.
The new end links are installed in the same manner as removal except an 8mm wrench is used to hold the stud. The 8mm hex on the end of the stud makes the job easier during the tightening process.
Once the nut is tightened on the stud with your 18mm wrench a torque wrench can be used to finish the job. All of the anti-roll bar end link stud nuts are torqued to 53 foot pounds or 72 Newton meters.
