I have a 2003 Mini Cooper R50. I started feeling something was wrong when driving it and thought it might have been a wheel bearing. I took it to a mechanic who drove it and said it was definitely a wheel bearing but he didn't know which side without putting it in his shop. I purchased and replaced both Wheel hub assemblies and it's still there. It seems to me to be on the driver's side, but I'm not sure. Could it be the axle itself or would it more likely be in the transaxle case? Is there a bearing the axel goes through as it enters the case? Sorry, newbie here to working on a mini and being a shadetree mechanic.
