Service Slants - Rough Ride, Poor Handling
I subscribe to a few automotive service trade magazines and they have some good information that you might find valuable. Here's a recent one concerning 2007-2009 Compass and Patriots:
Owners of 2007-09 Compass and Patriot models built before 04/23/09 may complain that the vehicle rides roughly or handles poorly when driven over bumps or rough road surfaces. One probably cause of the trouble is a leaking front strut. The leakage may occur on one or both sides of the vehicle.
Replacing the strut(s) and the jounce bumper and dust shield is the obvious fix. Note that the jounce bumper and dust shield are now two separate pieces, replacing the old inferior one-piece design. The part numbers are 05171137AB for the new bumper and 05171132AC for the new dust shield.
