Never seen a power steering cooler fail on one of these trucks. I have worked on them since they were new FWIW. They are generally good rides. The limited slip (if equipped) is not very tough, the clips break and can cause damage to the carrier and to the axle housing. The HVAC doors will break from time to time causing heating and cooling issues. This can be fixed by replacing the door stops with an improved design. The hemi is leaps and bounds better than a 4.7.
