I was pulling into the garage and i noticed when i turned the steerin wheel...it made a squeaking sound(from outside the car)....veryy embarassing when ur parallel parking somewhere.....same noise when the car is moving....i checked my power steerin fluid....its on the "min mark".....should i change it....i was thinkin bout lifting the car and have somebody turn the wheel and id be under the car lookin for the noise...however its still kinda nipply out so if somebody knows exactly what this is id appreciate it.....i recently put on 18s with 215/35/18 tires if that means anythin
