Reasons for the Rear of a Vehicle Swinging Left and Right When the Rear Wheels Pass Over Bumpy Roads

[NicoleDella]

When the rear wheels of a vehicle pass over bumpy roads, the reason for the rear of the vehicle swinging left and right is incorrect steering setup. The following are the possible consequences caused by incorrect steering setup: 1. Wheel bounce: Wheel bounce (up and down movement) will cause the wheels to deflect upward in an arc. This arc motion will change the distance between the tie rods connected to the wheel knuckles and those connected to the vehicle (front tie rods are connected to the steering gear, rear tie rods are connected to the chassis). The change in distance will cause the wheels to camber inward or outward, thereby affecting the vehicle's steering. 2. Deviation from the intended path: When the vehicle travels over bumpy roads, it will deviate from the intended driving direction. 3. Unstable driving: This will cause the vehicle to be highly unstable at high speeds.
