Subject:Popping Noise in the Footwell Area

Models:



The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:

The #2 lower body cradle mount may be moving within the cradle mounting hole on either side of the car. This may exhibit a pop noise in the footwell area during hard acceleration, braking or turning maneuvers. This noise may also occur while driving on rough roads.

Recommendation/Instructions:

Remove the lower portion of the #2 cradle mount (The second mount from the front of the car under the longitudinal body rail which is closest to the stabilizer bar) and apply epoxy material around the perimeter of the mount and reinstall it. Make sure the mount is clean and free of rubber flashing in the area in which the adhesive will be applied. The mount must be reinstalled prior to the epoxy "Setting Up" (Usually around 15 minutes). Perform this operation on both the left and right side mounts and allow the vehicle to sit for 2 hours after reinstallation.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
