After changing brakes, rear left wheel bearing and recently the diff (with inner CV swap) I am still getting what I can only describe as a Shhhhing noise from the left off car.

It is very obvious next to Walls or going past traffic. The noise is speed related and becomes a whirring noise at 50mph+

Has anyone ever had a front wheel bearing go? I am running out of options and was sure it was the diff as the old one is knackered.

Thanks

 

might sound daft but have you checked the brake heat shield. When stuff gets replaced sometimes it can get knocked and rubs. If not that it sounds like a wheel bearing especially if it gets louder or quieter depending on speed
