Every time i go over a bump i get a quick squeek from my front passenger wheel. It sounds a little bit like a bed spring. I was thinking about trying to lube everything up but the squeek doesn't go away when I drive in the rain. The squeek is temperature sensitive if that helps as a clue. In cold weather it goes non-stop on every little bump. When it's warm (over 60) you have to hit a pothole to get it goin. I was told it was a bushing but which one?

Thanks in advance,
