evest Posted February 27, 2013 Share Posted February 27, 2013 Hi folks, Got a wee issue with the zed. When starting the car, after a few seconds at idle there is a faint metallic vibration comes from underneath the car. It goes away when setting off, but returns a lot more pronounced when: - accelerating - any gear - approx 2750 - 3250 rmp (regardless of gear selection of speed) Sound like its coming from the passenegr side, but hard to tell for sure. Sometimes accompanied by a 'whoosing' sound at higher speeds (different to th eusual whoosh that is!). Initially thought it might be exhaust related - got a Cobra system and Berks HFC - on been on the car a couple of years and all looks in decent shape. As a separate problem, I'm fairly sure my front wheel bearings are on the way out - but might the two issues be related at all? Sorry this is vague I know, but any suggestions welcome. Will take into my local garage to get checked out, but would be good to go with some ideas! Cheers all, Quote Link to comment Share on other sites More sharing options...

Watshot Posted February 28, 2013 Share Posted February 28, 2013 I've had that kind of metallic rasp when exhaust heat shields have come loose. May be worth a check if you didn't notice it when checking out the exhaust. Quote Link to comment Share on other sites More sharing options...

BulletMagnet Posted February 28, 2013 Share Posted February 28, 2013 Was the y-pipe swapped out? If not, the heat shields around the OEM shield will develop a rattle, ripped mine off when they started Quote Link to comment Share on other sites More sharing options...
evest Posted February 28, 2013 Author Share Posted February 28, 2013 yeah i got a new y pipe with the cobra. it had metal braiding around the flex joints which had rusted so i ripped them out. problem persists though! Quote Link to comment Share on other sites More sharing options...
