Chrysler (China) Automobile Sales Co., Ltd. filed a recall plan with the State Administration of Market Supervision and Administration in accordance with the requirements of the Regulations on the Management of Defective Automobile Product Recall and the Implementation Measures of the Regulations on the Management of Defective Automobile Product Recall. It decided to recall some Jeep New Herdsman models from November 20, 2018, totaling 35. The car.
During the period from May 7, 2018 to May 10, 2018, a total of 35 new Jeep models were produced.
Some of the front suspension thrust rod brackets within the scope of this recall may not be welded properly, resulting in the separation of the thrust rod bracket from the frame, resulting in the reduction of vehicle steering capacity, increasing the risk of collision, and there are potential safety hazards.

The phenomenon that two objects move relative to each other to produce motion resistance between their contact surfaces is called friction, which is called friction. The existence of friction not only increases the power consumption, but also causes the wear of parts' contact surfaces. Therefore, lubricating oil is usually used between the relative moving surfaces of automobile parts to reduce friction. Failure of automotive parts 75% is caused by friction.
Friction can be divided into dry friction, liquid friction, boundary friction and mixed friction according to the lubrication state of the parts.
(1) dry friction
The friction between the frictional surfaces without any lubricating medium is called dry friction.
When the parts are in the state of dry friction, the surface of the parts is abraded sharply, so the surface of the moving parts of the automobile should avoid the occurrence of dry friction as far as possible.
Dry friction and boundary friction are the main friction between the upper part of cylinder wall and piston ring. Dry friction will occur when the journal and bearing are subjected to impact load in the working process.
(2) liquid friction
Two the friction of the friction surface when the lubricant is completely separated is called liquid friction.
In liquid friction, the two friction surfaces are completely separated by a layer of lubricating oil film with a thickness of 1.5-2.0um, which avoids direct contact between the working surfaces of the two parts. Friction only occurs between the lubricating fluid molecules, so the friction resistance is very small, and the wear of the parts is very slight.
Most of the relative motion parts of a car are carried out under the condition of liquid friction (for example, crankshaft and bearing).
(3) boundary friction
Two friction surface separated by a very thin boundary film is called boundary friction.
The oil film thickness is usually below 0.1um. Friction only occurs between the outer molecules of the boundary film, reducing the friction and wear of the parts. But its thickness is very small, and it is easy to be destroyed by impact and high temperature, so it is not as reliable as liquid friction.
For example: between cylinder wall and piston ring; if the work crankshaft and journal between the insufficient supply of lubricant, easy to produce boundary friction.
(4) Mixed friction
The friction between two friction surfaces in the presence of dry friction, liquid friction and boundary friction is called mixed friction.
In the actual working state, the parts usually work under the mixed friction state, and the friction state varies with the working conditions.

Automobile parts refer to the components of each unit of the automobile and all consumable materials serving the automobile. They can be divided into automobile parts, Automobile standard parts and automobile materials. The following is a detailed introduction.
（1）Auto parts are divided into parts, assemblies, component, and body panels.
Parts: the basic manufacturing unit of a car. It is an integral part that can no longer be disassembled. Such as: piston ring, piston, valve, impeller and so on.
Assembly: a combination consisting of more than two parts and acting as a single part. For example, a connecting rod with a cover, a pair of bearing shells, and a cylinder head with a valve guide.
Component: a combination consisting of several parts or assemblies, but can not function independently. For example, transmission cover, cooler cover, automobile steering connector, water pump and so on. Sometimes it is also called "half assembly".
Body panels: formed by sheet metal stamping, welding, and covering automotive body parts such as: radiator cover, leaf plate, etc.
(2) automotive standard parts
Designed and manufactured according to the national standards, the same parts are unified in shape, size, tolerance, technical requirements, and can be used in a variety of instruments and equipment, and interchangeable parts are suitable for automotive standard parts such as bolts, gaskets, pins, keys, etc.
(3) automotive materials
Automobile operating materials, such as various oils, solutions, automotive tires, accumulators, standard bearings (non-special), etc.
Most of the products produced by non-automotive industry and used by automobiles, generally not included in the catalogue of various types of automotive accessories, also known as "horizontal products".

We are setting up this topic to share information on any impact the current COVID-19 virus has on the auto parts industry. Sourcing, distribution, parts availability, and business impact. General questions and sharing of knowledge are welcome.
The WHO has designated this a global pandemic that is already affecting many industries, including most sectors in the automotive industry. Corporate and Independent automotive parts stores are being impacted by repair shop businesses slowing down. As you know, many parts come from China and other parts of the world, which are affected by the current pandemic.
Please share how this is impacting you and what you are seeing.
Who else is seeing industry shortages and inflation issues causing price and availability issues on auto parts? Manufacturers are short staff, supplies, and materials. Containers from China are backlogged and getting more expensive and add on top of that inflation, prices have and will continue to go up.
Chip shortages and user car prices going up, means more more for everything. New car prices are getting over sticker in some cases. Its all relative because even groceries are going up in price. Gas and oil prices as well. 🥵
