Hello everybody;

I've got a question to put infront of the board if you guys have a minute.
A friend of mine has a 1989 560 SEL with a vibration problem at higher speeds no matter how many parts he has had replaced.
It's hard to tell if it comes from the front or the back and doesn't stop when the tranny is put in neutral. Any ideas.

Also the drive shaft from the enging extends out to the flex disk then picks up a slight (maybe about 4 degrees or so) angle going to the differential. I don't know if this is correct . My 400E is in a straight line front to back. Any help would be appreciated.
Thanks
Brian
