My 2004 Pacifica (130k miles) was left parked for 2 weeks while we were away. Upon return it didn’t wqnt to back out of the parking spot. After about 1/2 revolution the wheels made a clanking sound and hung up. Rolling back and forth freed things up enough to drive the car to the mechanic (about 40 miles). And after the first mile or so everything seemed to go back to normal, with no absolutely signs of anything not wanting to turn smoothly… The mechanic thought that the problem had been that the brakes were sticking due to the car being unused and said nothing needed to be done. However, upon examination he found that we could use new front brakes and 2 motor mounts. He said that the need for brakes and motor mounts was due to normal wear and tear, and was not related to the wheels hanging up issue.
But now, immediately after installation of 2 new front rotors and pads and 2 new motor mounts there is a vibration/shudder when braking from anything more than 20-30 mph, which was never there before. The shudder is rapid and sometimes pronounced like going over the warning groves cut into the edges of pavement on the interstate. He thinks that this may be a sign that there is a driveshaft issue, and dismisses it as due to an out of round rotor since they are new. I don’t know what to think. By the way, he has always been an excellent mechanic, with a great reputation and loyal following.
