A "tapping plate cage" on the driver side frame rail may cause a squeak or tick noise while driving, this is often misdiagnosed as a suspension problem. The tapping plate is a threaded plate which accepts one of the front sub-frame mounting bolts. The "cage" of the threaded plate may be touching the frame rail causing noise as the vehicle is driven. "Adjusting" the rear tab on the tapping plate cage so it no longer is touching the frame should eliminate this noise.Google+

Dodge Grand Caravan Squeak or Tick Caused by Tapping Plate Cage
Dodge Grand Caravan Problem
Average Mileage: 48,150 mi (34,300 mi - 62,000 mi)
When brakes are applied going at a low speed, ie: drive thru and coming in the gates on base, there is a tapping/ticking sound coming from the driver's side quarter panel. I don't hear it when I am driving above 10mph, only when "creeping" in stop and go traffic. I just bought this van 4 days ago, so I am calling the dealership to schedule an appt. with the service department.
I'm having the same issue with 2010 grand caravan too. thanks guys for the update.
The shop we went to today while on vacation in Las Vegas diagnosed the "harmonic" I heard as a brake problem and $400 later.... I should have looked here first. I will check out this solution when I get home to my regular mechanic. Thanks.
