Just coming home from a night out and I was having a bit of a play with a Vauxhall caviler
on the M25 got it up to about 85mph and the car started to shake pushed it a bit further up to 105mph and it was so bad my eye balls were jumping out of my head
not long ago I had the wheels balanced so it cant be that
Please peeps throw a idea my way
Hey Carlos, I had the same problem with my 318is a few month back and it turned out to be the rubber flex disc and driveline support bearing, the flex disc or guibo as some call it, is near the back of the transmission and you can visually inspect it with the car on a lift or up on jack stands. if it has cracks or any nylon strings visible get it fixed quick, they can cause you major headaches if it shears apart. Also if the flex disc looks bad you might want to have the center support bearing replaced also. Either way you can look at the flex disc without paying someone else to tell you its bad. If your car has more than 100k on it you might want to replace them both anyway. hope this helps!
