Earlier this year when parking caravan using motor mover I could hear a quite loud click from one wheel and would momentarily stop then move again , so when parked I jacked up caravan and spun the wheel, no clicks and spun fine lowered caravan and click and momentarily stopping was back, so removed hub to check brake shoes to find that the wheel bearing had gone even though there wasn't any rumble or click without the weight of the caravan on it, changed bearing and all good, so could only put the momentarily stopping to of the internal bearings fowling each other, I am wondering if this could be the same problem but more advanced
