**update**

So last night I followed a thread here about replacing the bad Lower Control Arm #2 .

Thought this might fix my vibration/loud rumbling problem and it seems to have just slightly. Doesnt seem to have as bad now but its still there. What I have noticed is that I dont necessarily feel the vibration in my pedal or steering wheel anymore.

Now...I have done vigorous testing as I'm not a mechanic and I'm a little scared that my work is that great (loose bolts or something) so I've been a bit conservative with my driving since last night.

Any other thoughts?

- Upgraded rotors and pads: Yes, I bed them in as correctly as possible according to the instructions
- New tires: Will get them rebalanced today
- New LCA#2 : Will get alignment done today as well
