I have a 2003 TF in my car and ever since I put it in it sounds like I have straight cut gears. Would this be because of a pinion bearing failure or what do you think it would be. Just gets louder with speed.
any help or guidance is appreciated.
Thanks

 

$0 check is to look up the PPF to I believe pinch weld distance measurement, which I believe is a different way of checking pinion angle. That's where I'd start then go from there.
