DIAGNOSIS OF DAMAGES WITH CAR 

 

When a damaged vehicle is maintained, if damage is not found with chassis or suspension, 
then it could lead to more serious damage or breakage in the future. If a big distortion has 
occurred with chassis in the accident, then, besides measurement of axles and different fixing 
positions stipulated in this Chapter, the following parts are also to be tested.   

1. Steering system and steering clutch manipulating system: Check if the functions between 
locks are normal or not, and if there exists any distortion or breakage or not.   

2. Chassis: Check if there is any distortion or breakage with steering arm, general assembly 
of shock absorber, double-headed studs, stabilizer bar, bracing piece, or fasteners of engine, 
or not.   

3. Wheelbase and tyre: Check if there is any damage, and if there is any unbalance or 
mismatching or not; check if any profile or wall is cut off or not; and check the air pressure 
inside the tyres.   

Engine mounting, transmission case, and exhausting system: Check if there is any wear and 
tear or not.   

Finally, sufficient driving test will ensure a good condition of vehicles for them to be 
delivered to customers without question.

WATER TIGHTNESS 

 

After the body is operated or maintained, this is the most important instruction in this 
Chapter.  

If these instructions are not followed, water leakage will frequently happen inside the car, and 
it would be very difficult to determine the exact position of leakage, as water inside the car 
has many uncertain flows, and can possibly flow directly along the water channel.   

One pattern will also be observed that there will be more or less rain leakage when vehicle is 
being directionally driven in rain, while no water leakage can be found when it passes 
through car cleaning station or high-pressure nozzle. The reason for this happening is because 
of unevenness of the ground surface and the impact of bending and buckling stress on work 
of mechanical parts, so that rainwater enters rather poorly sealed areas.   

 

Many cases can lead to water leakage, such as:   

A. Problems with connection of body for welding errors.   

B. Spot welds are loosened for insufficient nicety work with metal surface prior to welding.   

C. Lacking of sealing adhesive for airproof position.   

D. Poor quality of sealing adhesive, or low-level sealing type.   

E. Problems with fitments of water tightness for general assembly of parts, etc.   

 

The above indicates that it is necessary for the general assembly of body to be airproofing so 
as to prevent water leakage. Therefore, after parts with body are replaced or the body is 
maintained, proper adhesives are to be used as per models of joints.   

Adhesives should have proper viscosity, elasticity, and resistance, so that they won’t break or 
loosen under the motion of body and change in temperature.   

Thanks to the advanced properties of manufacturing process for general assembly, sealing 
materials are not required for some positions. However, as the requirement of such process 
cannot be generally met during maintenance, all the welds must be well insulated, and 
corresponding sealing materials are to be applied for similar positions stipulated in this 
Chapter.

PROTECTION OF UNDERBODY PANEL 
It is to be reiterated here that during maintenance or replacement of welds or moveable parts 
of the body, if the protection paint inside the underbody panel or on the appearance is to be 
removed, then anti-rusting and sound insulating protection layer must be substituted after 
maintenance or replacement. Special attention should be paid to areas impacted by fatigue 
which mainly attributes to clay and sandstones ejected by wheels.
