e91 vibration

[johnwjones171]

my BMW 2.0d e91 get a rear vibration around 75-80 mph when cruising don't understand why It's not severe just can feel it any ideas out there would be appreciated

Wheel balance out? Wheel bearing perhaps, but that usually stars with noise before it gets bad enough you can feel it.

If wheels have been balanced, propshaft perhaps?

Some BMW wheels seem overly prone to getting banged up by potholes, maybe a quick visual check there.

Do E91s use a rubber donut/giubo at the back end of the prop? Those used to be a bit bad for going on the older cars.

Check rear wheel balance.

Thanks for info I'll start with balancing. then prop

I had this on mine thought it was wheel balance. It went in for service and the guys said the rear tyres were worn close to the limit especially on the inside edges. Changed the tyres and the vibration went.

When all else fails - wheels, mainly - remove the exhaust heat shield and examine the prop as I've had them before when they've thrown a balance weight off - you'll hopefully find it again! It'll fall out as the heat shield is removed. The result is a weird vibration/thrumming through the centre/rear of the car. They can be tacked back on with a mig welder easily enough.

Wheel weights, prop donut and engine mounts/gearbox mount would be a good place to start.
