Rear Drive Shaft Play

[simonriley11]

I have just done a full spanner check on the underside of my car. I can feel a bit of rotational play in the driveshafts by rocking the tyre and holding the inboard CV joint. Is there an 'acceptable' amount of play for the driveshafts and if so how do you measure it? Thanks.

Normally you can move the wheel about an inch each way at the tyre to take up the slack between the diff and the wheel. Then there is the same between the diff and the opposite wheel, so you have a lot of slack to take up before everything goes tight.
