If your vehicle is showing car leans heavily to one side when turning corners (body roll), here are the most likely causes and the parts you'll need to fix each one.
The sway bar (anti-roll bar) connects the left and right suspension to keep the car flat in corners. Broken links or severely worn bushings completely disable this function, resulting in massive body roll.
Shocks and struts control how fast weight transfers when turning. When the internal valving wears out, the vehicle loses its dampening ability and will quickly dive and lean heavily during cornering.
If suspension work was recently performed, a technician may have forgotten to reattach the sway bar link, or failed to torque it properly causing it to detach while driving.
Springs support the physical weight of the vehicle. A broken or severely fatigued spring will cause the car to sit lower on one side and lean excessively under cornering loads.
On vehicles equipped with air ride, a leaking air strut or failing control solenoid will prevent the system from actively leveling the vehicle during turns.
