For Cruiser’s squealing problem, look at the driving surFaCe — William William, we love having customers like you at the shop. Guys like you come in, having already diagnosed the problem and tell us you need grease plugs (whatever they are), a lube job and ball joints. We sell BY RAY MAGLIOZZI you all that stuff, and when you Dear Car Talk: I have a 2003 come back and say the car was still Chrysler PT Cruiser Limited Edition squealing, we can just shrug and say with 225,000 miles. It is running “Hey, you asked for all that stuff.” I think the squealing is actually fine, but when driving at lower coming from your tires, William. speeds and turning, like in our But I don’t think you need new tires, condo parking garage, it makes all either.

So when you turn the steering wheel, you end up dragging the tires — in tiny little movements — over the garage floor. The tires are intermittently sticking and then sliding a little bit. And that stick-and-slide creates the eeerrreeerrreeerrr squeaking sound you hear. It’s a lot like what you hear on a basketball court, as players stop and pivot and their sneakers drag along the court surface. When you’re on a normal road, it doesn’t happen, mostly because the pavement isn’t as smooth. Those chunks of asphalt create a much more porous surface than concrete, so not every square millimeter of your tire’s contact patch is touching the road. Plus, when you’re driving, there are other noises that would drown it out, like engine noise, wind noise, road noise and your copy of “Led Zeppelin IV.” What can make the squealing noise worse? If they recently resealed the garage floor. If you have wheels that are out of alignment and more likely to drag or scrub on turns. Or if you’ve been watching too many Charles Bronson movies, William, and are flying into your parking space at 30 mph. *** Got a question about cars?
