2004 Malibu Maxx

I have a 2004 malibu max with about 53,000 on it. I had new brakes put on in March and they told me that the lower control arm need to be replaced because the bearing was going. Since it is under warranty I took it to the dealer they told me there was no problem I just had a oil change 3 days ago.,
I just noticed a thick coating of grease on both front wheel wells, don't know when it actually started it caught my attention today and yesterday and today I have heard a clunking noise on the drivers side of the car but it will go away. Everything seems to be driving fine otherwise. Not sure where to start.
