Final answer:
A gear whine only when turning usually suggests an issue with the power steering system or the driveline components like the differential, axle shafts, or CV joints.
Step-by-step explanation:
If a vehicle has a gear whine only when turning, it typically indicates a problem with the vehicle's power steering system or the driveline components associated with turning. These components can include the differential, axle shafts, or CV joints.
A common cause of gear whine during turning could be low power steering fluid, which may lead to inadequate lubrication and thus cause the gears to produce a whining sound.
Additionally, if the noise is coming from the driveline, it could be due to worn or damaged gears in the differential or issues with the CV joints. It is important to have the vehicle checked by a qualified mechanic to diagnose and correct the issue to avoid further damage.
If a vehicle has a gear whine only when turning, the problem might be with the differential or the wheel bearings. The differential is a mechanism that allows the wheels to rotate at different speeds when the vehicle is turning. If the differential is worn or damaged, it can produce a whining noise when turning. Similarly, worn or damaged wheel bearings can also cause a whine when turning.
