One problem related to rear suspension shock absorber has been reported for the 2004 Jeep Wrangler. The most recently reported issues are listed below.
Multiple incidents of violent vibration in the vehicle front end, including the steering wheel and front wheels, are occuring after hitting a minor pot hole in the road. Incidents occur at highways speeds, normally 45 - 55 mph. The driver must reduce speed to near zero in order to recover safe and effective control of the vehicle. This vehicle defect appears to be the well-known and major safety issue in Jeep Wrangler vehicles known as "the death wobble". I purchased this vehicle new from a Jeep dealership and have had it professionally maintained per the manufacturer's instructions since the day I bought it. My spouse and I have both experienced this defect several times in the past few years, most recently on December 15, 2011. At this point, we've had the vehicle inspected several times and replaced a number of components on the vehicle, including the steering damper, four shock absorbers, and all 4 tires. , in addition, the suspension has been inspected numerous times in the past 3 years. Given the shear number of similar complaints by other owners, I feel that this is an obvious manufacturer defect that should be acknowledged and corrected by the manufacturer.
