Hey, got a stock BF2 Turbo with the zf, about 224k old, recently rebuilt the turbo with a ball bearing centre. Love it. Sheared the middle of the tailshaft mid 2nd gear after coming out of a corner into a 100 zone, was giving it a fair poke.. broke in the centre, went bang bang underneath, I have sheared a tailshaft on my old starion so into neutral quickly and stopped, my local guy got the tailshaft rebuilt with a few heavier items and bigger rubbers toward the gearbox (?), when I got her back had a turbo noise which turned out to be a couple of broken brackets around the mouth of the turbo, fixed, then first ride out everything kind of normal, well babying it a bit, went to overtake a car at 80kph and dropped it, vibrations. So either a unbalanced tailshaft or diff, have any of you come across this before before I send her back to the shop?? Gearbox operates fine, so don't think it's an issue...
