guys,whilst jacking up the rear of my my01 bug earlier under the diff i noticed the diff assembly moved slightly up and down (when jacking) in the subframe.

not wanting to crawl under the car with just the jack in place i couldnt see much but i was wondering wether these assemblys are rubber mounted which would account for the slight 'give'.

 

The diff is on rubber mounts. There are two to the subframe at the back of the diff. You can get uprated bushes from powerflex that will reduce any movement.
