Wiring in a resistor cancels out any power savings you get from led's.
I would advise against those tap splices I have seen many broken and badly corroded wires from them.
I live in WI and it's -6 outside but once it gets warmer I plan on doing a led conversion I will post the parts I use.
When you turn left you load the right wheel bearing so if the noise increases when you turn left I would think right wheel bearing... When you raise the wheels off the ground and shake the tire do you have any play? The shk shk noise is normally the sheet metal guard behind the brake rotor...
