Why doesn't the car move when reverse gear is engaged?

[KaydenDella]

The reasons why a car doesn't move when reverse gear is engaged are as follows: Rear axle failure: If the drive shaft rotates but the car doesn't move, the fault lies in the rear axle. When lifting the rear axle and turning one rear wheel, if the drive shaft doesn't rotate and the other rear wheel rotates in reverse, it indicates that all rivets of the driven bevel gear are sheared off. If the other rear wheel doesn't rotate either, the half shaft should be disassembled and inspected for breakage. Transmission failure: If the drive shaft doesn't rotate when the transmission is in a certain gear after the car starts, it indicates a transmission fault. The transmission cover should be removed to check whether the transmission fork is broken or the guide block fixing screws are loose. Clutch failure: If the drive shaft doesn't rotate in any gear, it is a clutch fault. Check for severe clutch slippage, whether all the spline teeth rivets of the clutch driven disc are sheared off, or whether the steel plate is broken.
