Condition
Customer states: There is a creaking or knocking type noise heard from the rear of the cabin when driving on rough pavement or thrusting the vehicle while cornering.
Workshop findings: The noises can be replicated in these driving conditions.  The noises are diagnosed as originating specifically in the rear cargo area from the sheet metal overlap of the left rear side panel and the left rear cross panel.
Technical Background
To rule out noises generated by the contact points of the rear lid to adjusting buffer please refer to TSB 2068691 (55 Noises from rear of vehicle / rear lid while driving) and make the corrections described in 2068691 should your diagnosis determine these areas as the source of the noises.  If these corrections have already been made and the rear lid noises have been resolved or if the rear lid to adjusting buffer contact is not the source of the noises, proceed with the repair described as foll
ows.
