Vibration/noise at 70 mph
My wife's 1997 XK8 has developed a strange vibration and noise at 70 mph.
Only on acceleration it sounds like tyre roar but the door mirror glass vibrates alarmingly.
It only happens between 70 and 90 mph on acceleration, as soon as you back of the throttle it stops instsntly.
I have just had all 4 tyres balanced by the company recommended by my usual indy garage and did watch him do it so know it isn't that.
Any suggestions?

............and there's always the chance balance weight(s) haven't been properly attached and dropped off.

Or if the weights were placed slightly off or if they didn't put the right weight on, the vibration might not manifest until it reaches a specific frequency. The wheel speed between 70 and 90 mph seems to be a somewhat common wheel balance issue for many cars.

This started weeks after a wheel refurb.
I got the wheels balanced to eliminate this or hopefully cure it.
It obviously hasn't cleared it.
It does look like a driveline problem but was asking in case anyone else had experienced this and had a known fault.
I will get to the bottom of it and post the results.
