Sorry mate but wots tdc?ain't got a clue when it comes to cars. was goin to attempt it 2moro but may just try and get a garage to do it. Is it easy to do? just I don't really trust myself doin it and don't want to f**k it up.
 
Sound cheers Carl hope it sorts this f**kin rattling out worth a try ain't it. To be fair it's not that bad but because I know it's there it's all I can hear
