I have a 2007 Ford Focus with 70,000 miles on it. I recently just had to have my passenger side hydraulic motor mount replaced. Drove it for about 3 weeks while it was bad. Then after that start to notice it's shifting a bit hard into 3rd gear, and have an appointment with dealership on Monday to diagnoise. Now today, as I'm driving in the city at about 25MPH, I start to hear this terrible loud squeaking noise coming from somewhere. Everytime I hit a bump, it made it go off. If I was on flat road with no bumps, I didn't hear it. So when I got home, I started pushing around on things inside the car to see if I can duplicate the noise. Everything looks fine. So I'm about to decide it was some weird freak occruance, and after getting groceries out of trunk and slam it down, I hear the noise! So I start pushing down on the trunk, and I can now pinpoint the noise to somewhere coming from the rear passenger side tire. Any ideas what could be causing either the tire or something the tire is connected to or in the area to squeak loudly when there is pressure put down on it? 3rd problem in a 2 month period, do the problems ever stop once they start with these cars??
