What Happened
The lock nut on your vehicle's rear axle is a critical piece that keeps the wheels stable. In certain Audi models, this lock nut can break due to corrosion, which can cause the rear axle to misalign.
Risk if Unfixed
If the lock nut breaks, your vehicle's rear axle could become misaligned, making it harder to control. This could lead to a loss of control, increasing the risk of a crash.
