I put on different lugs (on the one wheel) and the vibration went away. After a few days, I took them off and used the original lugs that were causing vibration and see what happens. I'm glad to say everything has been fine and the vibration is no longer existent... I'm still not sure what may have caused that problem the first time. But its gone now, so I'm not worrying about it.
After I re-assembled everything I went for a short ride. I noticed a tiny bit of vibration from the front left wheel. It became a lot more noticeable as I'd slow down. I didn't need to brake, but when I let the car slow down it became more noticeable. It almost sounded like grinding and it started getting worse. I pulled over and noticed the lug nuts were a little loose on the front left wheel. I re-tightened them and got home to find the same problem. Its kind of annoying me. I do need to have that wheel re-balanced because its slightly off-balance but I do not think this will fix the issue since it was like that about a week ago before I installed the brakes/studs and there were no problems.
Any ideas? It only happens on the driver side. Passenger side is fine. I put the car on jack stands and inspected the wheels while my brother gave it some gas. Everything appeared fine and I didn't hear anything.
