My wife drives a 2005 Toyota Camry with the 24V V6 motor. I inherited it from my grandmother when she passed and the car only has 91K miles on it. It's developed a bad squeal when you crank it up and when you turn on the air or heat. I'm not sure where to start checking. I know there are two belts on it and it appears that the power steering pump is leaking a bit. There is a wobble in the steering wheel until you get to about 20 mph. Any thoughts on where to start? It's the family vehicle, so I want to make sure it stays in excellent condition.
