Last night, myself and me lady were poodeling along in the astra having a chat when we approached a roundabout. I go round this roundabout everyday without issue, however, this time round the back decided to swap ends with the front for no apparent reason I WAS NOT hammering it AT ALL! we were actually just talking and i was doing about 15/20mph going round the bend when it happened.

The wheel bearing seems to be in order, plenty of air in the tyres and no obvious signs of anything wrong. But there blatently is.... ive never known a 1.4 auto FWD car to just break away like that without having something fundamentally wrong with it!

any ideas? suspension seems to be all good too
