Is replacing the rear axle considered a major repair?

[Leon]

Replacing the rear axle is considered a major repair. The rear axle refers to the rear drive shaft component of a vehicle's power transmission system. It consists of two half-axles that enable differential movement and also serves as a device to support the wheels and connect the rear wheels. Depending on the suspension type, rear axles can be classified as rigid or independent. The functions of the rear axle are: 1. To transmit the power from the engine, which comes through the clutch, transmission, and driveshaft, to the wheels via the differential, reducing speed while increasing torque; 2. To bear the load of the rear axle; 3. To transfer the reaction forces and moments from the road surface to the frame through the leaf springs.
