Some time back, I posted a message requesting ideas about why my 2002 T&C Limited might sound like the front wheels are coming off. After replacing anti sway bar links and bushings - at considerable cost - the noise did not go away, although links and bushings were worn badly. Car has 50K miles, by the way. Finally, the local dealer service guy came up with the idea that there was a problem with the steering gear. It was a major project that cost nearly $700. The upside is that when I drove the car home today, the noise was gone.
The service manager's idea is that the design of the attachment of the tie rods to the gear is the weak link and that local rough roads are probably more than that design can handle over 40K or 50K miles. So, if you live in the land of potholes, even if you drive carefully (I'm an old geezer and do drive pretty slow), and you start hearing a dreadful clunking noise, look out for that steering gear.
