Car owners repair auto parts well hung ball joint reminded to pay attention to the following aspects, don't let the "silver" easily fitted to go.

Don't ignore the packaging information

Buy auto parts often can easily find flaws from the package, should be carefully identified. Ball joint says the Enhong general, genuine packaging box on the handwriting clear, overprint accurate, vivid colors, marked with the product name,specifications, quantity, registered trademark, factory name and address and phone number, has the certificate and inspectors chapter, some important components such as generator, electrical appliances and so on, are also equipped with specification, in order to guide users to the proper use and maintenance.Some auto parts will mark the origin is the "Indonesia", "French", but can notprovide the relevant import customs formalities, the true and the false of products is also difficult to judge, many may be counterfeit products.

No surface wear

Buy new parts surface should be no wear, if it is found that the surface wear, orpainted parts opened surface paint found the old paint, should be discardedcamouflage, then we must return.

Rotating parts to be flexible

Steering knuckle is one of the main parts of automobile steering bridge, can make the vehicle stable running and sensitive transfer direction of travel. The purchase of rotating parts, turn it will feel no clamping, rotating freely. Rotating parts rotationis ineffective, the components of internal corrosion or deformation, can not buy.

Binding site should be flat

Spare parts in handling, storage process, due to vibration, bump, often deformationoccurs in the binding site. Shaft parts inspection process, the shaft on the glassplate or other rolling with planar objects. Look at the junction part and the plane to judge whether the light leakage of straight shaft parts or not.

The adhesive parts without loosening

By two or more than two parts assembled parts, parts are through the pressing and bonding or welding, does not allow loosening between them, such as oil pump plunger and a regulating arm through assembling; clutch driven wheel and a steel sheet is riveted joint, the friction plate and the steel plate is riveted or glued; the paper filter frame and filter paper is glued into; electrical equipment thread isformed by welding. When the choose and buy if found loose, should be replaced.

No rust parts surface

Parts of qualified surface, has certain precision and burnished finish, the moreimportant parts, higher precision, more stringent packaging rust and corrosion.When you purchase should pay attention to check, if found parts rust spots, mildewspots or rubber cracking, loss of elasticity, or the journal surface has obvious toollines, should be replaced.

Assembly parts without missing components

The formal assembly part should be complete and intact. Ball joint said the Enhongif some individual small parts assembly on the missing, lost, will make the parts can not work normally or even discarded, resulting in potential safety hazard.
