My Wife's 1.0 Polo ('93) has developed a droning noise from the front left wheel that is only apparent above 30mph. I suspect it's the bearing, but I wanted a bit of advice before I tackle it. I can't say for certain if it's the wheel bearing or the inner (gearbox) bearing, or indeed a CV joint. It doesn't clunk on full lock, so I'm guessing that rules out the CV joint.

Are these a nightmare to swap out ? I was planning on stripping it down and taking the hub to a local engineering works to get them to press out / press in the bearing ona hydraulic press as I don't fancy half a day's frustrated bashing with a hammer :-)

What are the chances of it being the wheel bearing vs the inner (gearbox) bearing ?

Many thanks !
