E53 rear noise - rumble / vibration
 

Hi Guys

I'm at a loose end here. My 2004 3.0D is still making an intermittant rumble / groan / vibration from the rear.

I occassionally tow a caravan and this makes it slightly worse, but it is there at all different times.

• More often than not around 40 mph
• If i floor it, the rumble is loud
• If I corner with a bit of speed, the vibration is bad, but it can vibrate a lot on a straight road too.

To date I have been to 3 garages (a tyre shop, a wheel balancing place and an Indy) and nobody can find anything.

It has recently had:

• All new tyres
• Hunter wheel alignment
• Full service
• Rear brake calipers stripped and cleaned (they thought it could be a sticky caliper)

Can anyone suggest anything? The vibration feels almost like the rear wheels are loose (they are not).

Thanks in anticiaption.
