Replaced water pump. Started to install the timing belt when I noticed the rear cam (next to the fire wall) was off by 1 tooth. Instead of using a breaker bar I grabbed a ratchet. The gear spun (slid down the cam), so I turned it clockwise back to the mark. All 3 marks are aligned TDC on compression stroke and rotor pointing at #1 spark plug but car won't start.

I need to know which valve to use to charge my a/c

About to buy a '95 Plymouth Acclaim, but owner says the rear axle needs to be replaced. Says it only makes a noise and does not interfere with handling. Wondering how much of a problem this is, should it be replaced right away or can it wait, how much should it run me in Tallahassee,FL?
