night before last the camry was running rine.went home and the next morning i started the car and heard a light groaning noise and what sounded like a sqeuking from belt.so i looked and the crank pully had about 1/8 inch wobble.car still drives fine but havent went far. im buying a new crank pully tomarrow. my main question is do i need to worry about messing the timing up if i use the starter trick to loosen the bolt. is there any special directions on installing new crank pully? thanks in advance
