I had the same thing happen to me last year! Started knocking when on full left lock so took it into my local garage with the instructions "offside front wheel bearing sounds nackered"

Pick the car up later, sounds fine until I tried pulling into my garage and it was like i had left the handbrake on. Took the wheel off and discovered that it was only held on between the caliper and the main hub.... the nut fell off in my hand when i took the wheel off. When i went back to the monkey mechanics the next day, they had replaced the nearside front wheel bearing
