There have been a couple of Mopar part number revisions, so hopefully the newer bushings are better.
When replacing control arms, etc. it is important to leave the fasteners loose until the weight of the vehicle is on the ground at road-attitude. Then torque the fasteners to the correct values.
If the fasteners are tightened with the vehicle off the ground and the wheels hanging, this will introduce a 'twist' to the rubber bushing once the car is sitting on the ground. This can stress and eventually tear the new rubber bushing.
