Rear noise help...

[samcoombes]

Hi Guys

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

• I occasionally 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 anticipation.

i would say wheel bearing on the way out??
or you have a suspension bush going.

See may threads on here, you need to deflate the air springs to check for sure
