2002 Ford Focus noise

hi guys, i have just (4weeks ago) had a new steering reck replaced since then i have a noise seems to be from the passenger front wheel it sounds like something loose, rattling. i may be wrong but it seems worse when turning, braking or if going slow on bumpy road its banging like mad....i took the car back 2 weeks ago because they hadnt fitted a bracket to house two pipe running along the rack. i did think this was the problem now iam not sure...i have just taken the wheel off to see if i can see anything loose but nothing.. the only thing caught my eye was the tyre it still as good tread but the inside has worn? anybody got any ideas please...ive been readind up on it in the haynes manuel..it points you to incorrect wheel camber? whats this??
