						I happened to be under my Disco 4 recently and noticed two large weights.
They are at the rear just inside the bumper on either side and appear to swing freely.
What are they for?
Cheers.

						What happens if you only remove one?
Sent from my GT-I9305T using AULRO mobile app
The words of the old WW2 song come to mind:
"Hitler has only got one ball"
So possibly you get a BMW X5:-D
Harmonic balancers, remove and theoretically more vibration!

						Read this a little time ago on another forum. More like a design fault/fix.

This discussion makes me want to gaffa tape mine so they don't move and go for a short drive to see what they actually do ... anyone done that ?
Possibly some kind of strap or rope may be more appropriate ...
