Stabilizer links form the crucial connection between your stabilizer (a.k.a. the "sway" or "anti-roll") bar and wheels. The links are vital for proper handling on tarmac, but they may prove to be a liability in some other applications.
Stabilizer Function
These bars act as a flexible link between wheels on opposite sides of the vehicle and help to prevent runaway wheel harmonics and body lean.
Link Function
The stabilizer links ("end links") connect the springy anti-roll bar to the steering knuckles, or "spindles," on which your wheels are mounted.
Construction
End-link shafts are made of high-strength steel and have a rubber or polyurethane busing on one end. The opposite end of the link is usually secured to the sway bar and spindles with castle nuts and cotter pins.
Failure
Failure symptoms can include poor handling, excess body roll, suspension "thump" while cornering, steering dead zones and high-speed instability.
Removal
Many off-road enthusiasts use quick-disconnect end links, since anti-roll bars can seriously limit suspension travel.
