Rear End Judder

[M3ACS]

When ever i spin the back wheels, on a straight road or slightly out of a turn the back end seems to judder, like im wheel spinning over mini speed bumps :119:

Is this normal?

A sign my RTABs need changing and a trip to Simpsons is in order, or something more worrying

All traction control is off

IT could just be the back of the car tramping as it trys to lay down the power. But it will not go wrong geting it checked out.

I also tried the same thing on different roads and found similar effect

What are the signs of worn RTAB?

It feels lose at the rear and as if it will slide when cornering fast
