Why does my Vauxhall Insignia have a shaky steering wheel?

I've noticed that my Vauxhall Insignia's steering wheel starts to shake when I reach higher speeds. What could be causing this issue and how can I fix it?

The most likely cause of a shaky steering wheel is an issue with your car's tire balance. It could be that one of your tires is unbalanced or damaged, causing the shake. You should take your car to a tire specialist and get them balanced or replaced if necessary.

Another possible cause could be worn out suspension components. If your car's suspension is not functioning properly, it can result in a shaky steering wheel. Take your car to a mechanic and have them check the suspension for any issues.

It's also possible that your car's alignment is off, causing the shaking. This could be due to hitting a pothole or curb or just general wear and tear. Have your car's alignment checked and adjusted if needed.

One last thing to check is your car's wheel bearings. If they are worn out, they can cause the steering wheel to shake. A mechanic can easily replace them for you.
