SUBJECT
Rear Axle Support Repair Procedure
MODEL
E46 (3 Series)
SITUATION
Under certain circumstances, a fracture in the steel body structure could form in the area around one of the rear axle carrier mounting points. As a result, a distinct clicking noise can be heard from the area of the rear axle carrier during certain driving conditions. Specifically, the noise may be heard during load reversals on the rear axle, such as when starting from a stop, engaging forward or reverse gears, or when rapidly changing gears.
A repair procedure has been developed to repair damage to the rear axle support where the rear axle carrier is secured to it. This repair procedure is not included in the repair manual in the Technical Information System (TIS).
If damage is found in the area of the left rear of the rear axle support, the procedure shown in this bulletin should be used to determine the appropriate repair procedure.
