Guy's, I'm onto my 3rd clutch bearing in 20,000Km !! (started at 40k, now at 60)
Mine started off as quiet, only at warm up, but slowly got worse till it wails !!
Toyota still scratching their head as to what is causing it. Foreman at my dealership reckons this is the first model not to have a spring on the bearing and thinks it may not be retracting properly. He's sent a product report to Toyota, and is meeting with them at end of the month. Mine squeals terribly at the moment - get looks from other cars when I'm stopped at lights !!
