The plane which is defined by the head-to-foot and anterior-to-posterior directions in the human body. A stack of images acquired in the sagittal plane separates images by their left-to-right locations. The mid-line sagittal plane bisects the left and right half of the human body.
Under heavy braking, the rear tires lock up and the axle begins to bounce; the amplitude of the bounce becomes so severe that the tires finally develop enough traction (when slamming hard against the pavement) to rip the whole axle assembly free of the vehicle.
The antiroll bar's attaching links can become loose. Check the bushings. Worn-out shocks or struts are common culprits here. When the internal hydraulics wear out, the piston will move without the proper resistance, then stop short when you hit a bump. With shocks, another thing to check for is loose or dried-out mounting bushings. A groaning noise when you turn the wheel typically means there's a dry joint, likely at the idler or pitman arm. That husky stabilizer bar, the part that helps keep a car level in a curve, is often the source of noise.
