I assume you're pushing the wheel in or out or side to side? Is the wheel tight, and the CV nut tight? You have to be a little more specific if you want a definitive response.
Well u may aswell take the cv joint/drifeshaft out of hub and check if its got play.
I did mine the other day and there was so much play it was a joke, worth checking because there quite hard to find for sale unless you wanna buy brand new!!!
