I've noticed the same issue after changing the front shocks from OEM to KYB - and while I don't think the shocks are to blame, it could be that there's been an issue which the old shocks covered up by not working at all after 230,000kms. I've also changed the CV joints in mine, replaced the front suspension bushings; hoping that a wheel alignment and new tyres helps this - will post back in the morning the result.
