Two problems related to engine clicking and tapping noises have been reported for the 1996 Chrysler Concorde. The most recently reported issues are listed below.
Going 70 mph on a freeway car and steering wheel began to vibrate violently. Heard clanking noise exit the freeway. Valve head was almost broken through due to rocker arm shaft mounting boss breaking. Had to receive roadside assistant. Chrysler was aware of the problem and issued a service bulletin to machine shops about what to do. The bolts had to replaced.
A popping noise has been present since about 12000 miles. Repeated attempts to find have not resulted in a cure. At 35500 miles I insisted that the front end be completely checked. The four front cradle mounts were replaced but the noise continued. Additional checking revealed a left front axle that was defective. This still did not stop the noise. The rack and pinion steering assembly were replaced with only moderate changes in the noise. Now a left front strut and mount are being replaced. I have no assurrance that this will correct the problem. I know of one other Chrysler Concorde that has experienced rack and pinion failure in the past 30 days. This occurred while stopped at a traffic light. I have encouraged him to report this to the ntsb.
