I think you're probably right. I think I might change the wheel bearing and see if that fixes it.

Wow! I see what you meant now. I was imagining more of a Duke of Hazzard type situation!

To be fair I don't think that's been done. Would I be thinking the only fix would be a new driveshaft if it was out of balance?

Thanks for the quick reply. That does sound like a very similar scenario! I find it hard to understand how I could have damaged the CV joint and nothing else, but it seems like it might we worth having a second look at that.

Back in 2021 on holiday in Devon I hit a bad pot hole. No obvious damage so I thought I'd got away with it until the drive home. Once I got on the motorway it was the first time I'd got up to 70mph since the pothole, and there's a humming coming from the front passenger side corner of the car. Couldn't see anything obviously wrong so I assumed I'd probably lost a wheel balancing weight. I've had wheel balancing issues before and in my experience I can normally feel it through the steering wheel, but not getting any vibration there. Once back home I got the wheels rebalanced and the alignment checked. Neither fixed it. Back to the garage the mechanic suggested it was maybe a wheel bearing but couldn't be sure. Plan was to monitor it and if it was a wheel bearing it would get worse, then we would definitely know. Three and a half years later the hum is still there, no better, no worse. Irritates me on every motorway journey but I've never got to the bottom of it. Please help me fix it! - It's definitely related to wheel speed, not engine speed. - I've changed tyres, changed brakes, swapped front and back wheels, no change. - I've had several MOTs and services, nothing relevant has ever been flagged up. - Suspension and driveshafts all look fine, no obvious damage or play. Recently I'm getting a bit of a "hammering" sound when I pull out quickly turning hard right (like out of a T junction). The first time it did it I thought it was wheel spin, but it's done it a few other times when it certainly wasn't, and no traction control warning on dash. I've also noticed it making a similar noise when I reverse out my driveway (at very slow speeds obviously!) with the steering wheel hard right. I thought this might be a CV joint and could be related to the humming, but when I took it to the garage they said it was fine and couldn't find anything wrong. Every time it goes to the garage they can't find anything wrong. What else can I check that might be giving me these symptoms?! It's a 2016 Octavia vRS TSI 230.
