Why is the Rear Differential of My Ford Puma Making Strange Noises?

I have noticed that my Ford Puma's rear differential is making strange noises while driving. What could be the cause of this and how can I fix it?

The problem could be due to worn out bearings or gears. It is best to get it checked by a mechanic as soon as possible to avoid further damage and costly repairs.

It could be lack of proper lubrication in the differential. Make sure to check the level of the fluid and add more if necessary.
