Securing Rear-Axle Cross Member

Information 

• Use an auxiliary tool (stud or old fastening screw with the screw head cut off) to install the rear-axle cross member on the body. This is required so that the fastening screws are not screwed in crooked, thereby causing irreparable damage to the aluminum thread (in the body). 
• Observe specified tightening torques + torque angles. 
• The screws on the rear-axle cross member must be replaced. 

1. Fit rear-axle cross member on the body. Use an auxiliary tool.
