Possible transmission fault

[Sarony76]

Hi, my 2014 Insignia tourer SRI auto 62k has developed an intermittent scraping/grouching noise on a right hand lock my local garage has diagnosed the differential, I’m not convinced it’s fine left lock and straight on there’s no vibration either way I’m more suspicious of the drive shaft/cv joints, any thoughts

Sounds more like a CV joint than a differential which would normally make a noise in both directions if worn bearings.

Check that the wheel bearings are showing signs of wear on all wheels
