I have a Focus 1.8 TDCi 2009 135k miles, however the query could relate to any car.

I feel 'play' in the transmission when changing 1st to 2nd or stop-start in 1st or reversing. I jacked up each front wheel in turn, put in gear (with engine off) and could feel free play, along with a 'clicking' as I turned it back and forth. Was just under 1 inch movement at the tyre, same on each wheel. Amount of play didn't seem to change whether in 1st or 5th gear (although in 5th I could start to turn the engine so the free play was more disguised).

My question is how much rotational play/movement is normal? Could it be something to do with a worn CV joint? (I have just had the DMF, clutch and slave cylinder replaced, but I don't think its the DMF/clutch, as the movement would vary with the gear).
