12.6.2 Description and operation 

12.6.2.1 Bottom of frame and body 

The frame at the front and rear of vehicle is a subframe which is isolated from the body by rubber bushings. It 
provides support to the powertrain, the lower control arms of front suspension and the power steering gear with tie 
rod assembly. Any misalignment will lead to the wheels misalignment. The frame is bolted to the body by the 
rubber bushings. The underbody must be properly positioned in order to ensure proper suspension and wheels 
positioning. The individual underbody components contribute directly to the overall strength of unibody. Use 
proper welding techniques during maintenance operations to the unibody. The part must be protected against 
corrosion as long as the body repair operation is damaged or the original surface is damaged, refer to 

12.12.2.4 

Corrosion Prevention

 in description and operation of "Collision Maintenance". 

 

12.6.3 Diagnostic information and steps 

12.6.3.1 Diagnostic Information and Procedures 

Inspect the underbody. 

If the size of the body bottom does not accord with standard, a body correcting frame is used for correcting the 
size of various parts of the body in accordance with the requirement, refer to 

12.12.1 Specification

. 

Inspect the Frame and the Body Positioning 

Perform the installation procedure of frame. If the frame can not be correctly installed to the body, the frame and 
body positioning is incorrect. Confirm the body positions exactly to replace the frame.

12.6.4 Dismantle and install 

12.6.4.1 Maintenance of frame 

Inspect for the possible damage to the frame and indirectly judge the frame positioning by the following. 

The frame can not be correctly installed to the body. 

– The right geometric relationship among the steering arms. 

– Correct wheel position 

If the frame is damaged in any form, replace the frame. Do not attempt to repair the frame.
