Untraceable vibration
Discussion
Hi, I’ve got an e46 330i touring and I’ve been chasing a vibration for about six months, so far I’ve had the front wheel bearings replaced, front discs and callipers, front control arm rear bushes, springs/shocks all round. The wheels have been balanced 10 times by 8 different garages, 4 new tyres, driveshaft flexi disc, centre bearing & cv joint replaced. Also replaced wheels in case they were buckled.
The front control arms were replaced about 4 years ago.
The car has been checked over by 3 garages for worn bushes etc, I’ve also had 4 wheel alignment done.
The front was better after the work done on it but the vibration feels like it’s coming from the rear, it’s at its worst above 65 mph and doesn’t go at higher speeds.
So far I’ve spent £4100 and still got the same vibration.
Anyone with any ideas please?
Thanks in advance.

To me; it still sounds like it's doff/prop/bearing related
I'd deffo replace the diff bushes; I'd also check that the guibo has been fitted the correct way, with the arrows pointing forward as they should. This is often overlooked
Worn bushes don't always show when they're 'inspected'...
As an example; my Japanese import E39 touring; I replaced the rear subframe bushes (which I'd highly advise to do on your E34 also); remove them all but all looked ok until fully removed and the front 2 had completely split!
That couldn't be seen until removed!
Replaced them all with Meyle HD ones and the cars handling and ride was transformed massively!
I’ve been thinking back to when this all started, I had a leak on a tyre valve where it goes through the alloy wheel. To replace it the garage deflated the tyre and pushed the sidewall in to access the valve, all didn’t got to plan and the tyre got quite deformed and they had hell of a job to get the tyre back into shape. All was well until a few weeks later when the vibration started, it’s quite possible I suppose that the sidewall was damaged and weakened.
