Your ball joints (lower or upper) need to be changed.
Hi, I had same problem as yours. If you don't change it, you will lost control of your direction on the way (dangerous on highway). Check with any garage to do the job, it is easy and not expensive.:mad:
I got the same problem as yours, it may be because of your CV drivershaft.
The guy in garage told me: it's not dangerous, only cause your car stop.
Go to change, it's around $120 including all.
Hope it's useful
