2004 Fiesta Wheel Bearing

[rdm]

Hello,

I've got a stock 2dr 2004 Fiesta Zetec which has just had the front left wheel bearing collapse for the second time in eight months. It's a $950 job to replace it, which I had Etheridge Ford do last time. What I wonder is, what might be causing the collapse? It isn't just going squeaky or giving some play, it's absolutely vaporizing and combusting. Might there be another problem causing this? Do Ford offer some sort of warranty on repairs?
