Symptoms of sway bar problems include squeaks, excessive leaning when the vehicle turns and over-steering. Connected to the wheels on both sides of a vehicle, the sway bar balances and stabilizes the weight of the vehicle between the two sides of the suspension.
Sway bar links connect the sway bar to the suspension, and they create tension on the bar so that it can resist body roll when the vehicle is turning. Driving a vehicle with broken or worn sway bars and links creates safety hazards for people and vehicles on the road because the vehicle's condition impedes the driver's ability to maintain proper vehicle control. Mechanics may repair or replace sway bar link bushings and links, depending on the extent of the damage or wear.
