1995 NEONS - POPPING NOISE IN FRONT SUSPENSION WHEN TURNING
INVOLVED VEHICLES:
1995 DODGE/PLYMOUTH NEON VEHICLES BUILT PRIOR TO MARCH 20, 1995 (MDH 03-20-XX)
SYMPTOM/CONDITION:
Popping noise from the left, right or both sides of the front suspension while making sharp turns at low speeds, less than 10 mph.
DIAGNOSIS:
Road test the vehicle at speeds, under 10 mph in a large clear area without traffic.
Turn the steering wheel to almost full lock clockwise, but not against the steering stop, while backing up the vehicle. Stop the vehicle rapidly without locking the brakes. Turn the steering wheel counter clockwise to almost full lock position while slowly moving the vehicle forward. Stop the vehicle rapidly without locking the brakes.
If a popping noise is not heard, repeat the above maneuvers EXCEPT turn the steering wheel counter clockwise while backing and clockwise when going forward. This diagnosis may have to be repeated several times on some vehicles to create the noise condition. If the popping noise is heard, proceed to the repair procedure.
If the popping noise is not heard, some other noise may have been present and further diagnosis and repair of the front suspension may be required and will not be covered by this procedure.
