Hello all I have a 2006 tj I have a grinding noise in the front driver side. It's not the tire and my ball joints look newly replaced. I just bought it a few weeks ago. It is lifted about 3" and has 33" tires on it. This is my first wrangler so I'm still learning. I'm thinking this could possibly be u joints?? It started out just when I was braking and that was last week now it does it sometimes while braking and while I'm driving down the road. Any suggestions as to what it may be would be very helpful I can't get it in the garage for a few more days.
