hey guys,
got a 2006 mk5 golf gt tdi with 2l bkd engine.
saturday my little brother and i installed new sway bars, drop links and coil overs front and rear, took it for a test drive, drove it quite hard in fairness.
anyway, it started off all good but on the way back theres aggressive vibration. this vibration is from start up to about 1400rpm. its there when changing through gears, clutch in and out, worst at 1200rpm.
engine mounts where done about a year ago, ball joints, track rod ends where all done as well, wheel bearings been changed. no vibration was there after these jobs.
its only since driving it quite hard. i will admit, we was unable to get the axle/cv bolt out of the knuckle so we disconnected the passenger side cv axle from the gear box to do the coil overs. not the first time i've done cv axles and it all went back together perfectly.
we made sure everything was torqued down to the correct spec and tight.
so im wondering what could be causing the vibration, its there on cold and hot start up, under load pulling off, between 1200-1400 rpm regardless of gear and with clutch in. also at idle in neutral not moving but not as bad.
