in the last few days i have been hearing this rubbing noise from the driver side wheel well, and the only thing it could be is the CV boot rubbing on its self cause its dry. I know that i should replace it and i will when i have the money, but is there some kind of lubricant i can put on to make it quiet again without damaging the boot any.

 

Silicone spray, or waterproof lithium grease - however, either will attract dirt and cause the boot to wear externally. It may quiet it down a bit though. The grease will last longer.

Disclaimer: if the noise is being caused by one end or the other of the boot having come off it's seated position with the clamp in place, this method will not help you.

Replace the CV asap if it has been exposed for a while.
