Why is my Vauxhall Astra's steering wheel shaking?

When driving at high speeds, I've noticed that my Vauxhall Astra's steering wheel starts to shake. What could be the cause of this and how can I fix it?

The most common cause of steering wheel shaking at high speeds is an unbalanced wheel or low tire pressure. I suggest getting your wheels balanced and checking your tire pressure to see if that resolves the issue.

Another possible cause could be worn or damaged suspension components. Have a mechanic inspect your control arms, tie rod ends, and ball joints to see if they need to be replaced.

It's also important to check your alignment, as misaligned wheels can also cause steering wheel shaking. If your alignment is off, have it adjusted by a professional.
