Condition
Some customers may comment on a snap or popping-type noise coming from the front of the vehicle. This condition is most apparent during hard left or
right turns at low speeds. Going over bumps while turning may also aid in producing this noise.
Correction
Remove the bolt-in front crossmember and add washers using the procedure listed below.
DO NOT slot the mounting holes on the crossmember as stated in previous bulletins. Slotting the holes has been found to be less effective and, in some
cases, causes the noise condition to be more prevalent.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
Remove the mounting nuts, bolts and the front crossmember from the vehicle.
Clean all the undercoating off the crossmember in the area of the mounting holes.
