What causes rear axle tramp?

Rear axle tramp is typically caused by a combination of factors including inadequate suspension design, worn or damaged components, and tire issues. It often occurs when there is excessive force transmitted through the rear axle during acceleration or braking, leading to a loss of traction and oscillation of the axle. This can be exacerbated by modifications to the vehicle, such as changes in ride height or the use of performance parts that alter the suspension's geometry. Proper maintenance and alignment, along with the right tires, can help mitigate this issue.
