Could anyone tell me what's up with my Saff, recently it been driving pretty funny, at 45mph or over til about 80mph the engine sounds harsh, no other way I can describe it just 'harsh' like a booming noise that I used to get on my 8v XR2i many moons ago, that was just a characteristic of the CVH but haven't got a clue about this, I dunno whether it's the diff or engine. Also any one who'd people would recommend to rebuild my engine in the North East area???

Thanks
