noise from drivers front wheel

I have a noise coming from my drivers front wheel. i have changed the bottom ball joint as that was definately worn but the noise has got worse, i am assuming it is now the wheel bearing...if it is how difficult is it to change this?..i have done rear bearings before on other cars but not the front..any thoughts or tips...thanks

I am getting a knocking noise from around the front right wheel it starts as a tapping and builds to a god almighty banging. Have had the mounts replaced -worn but OK. It does not seem related to bumps in the road or speed although there seems to be an associated squeek with bumps. It s not the CV's but I am concerned as the noise is too loud to even shout to one another. As always refuses to do it for the garage and they are just replacing parts at an expensive rate.

Anyone any ideas ?:banghead:
