What we call shock absorbers are really "dampers." The springs in a vehicle's suspension absorb bumps and other road shocks by compressing, and the shock absorbers control the amount of bouncing created when the springs rebound.
Several warning signs can tell you when Dongfeng shock absorbers need replacing, such as your car bottoms out over railroad tracks, speed bumps or dips in the road or keeps bouncing well after the fact. Other signs are unusual noises over bumps, excessive body lean in turns or that the front end of the car dives sharply in hard braking. Because shocks wear out gradually, you might get used to a looser, bouncier ride, much like you get used to longer stopping distances as brake pads wear out.
One way to test shocks is to push down hard on each corner of a vehicle. If the car continues to bounce after you let go, your shocks need replacing. However, this test may require quite a bit of strength, and with many high-riding SUVs and pickups it isn't easy to get the leverage you need. Instead, you should have a qualified mechanic check your shock absorbers when your Dongfeng heavy truck is on a lift, such as when you have tires rotated. The mechanic will be able to see if there are major leaks (shock absorbers are filled with fluid), worn mounts or bushings, or physical damage such as dents.
Despite advice to replace shocks at specific intervals (often from those who sell replacements), such as every 50,000 miles, when you need to do it can vary by Dongfeng commercial vehicle and how and where you drive. If you frequently drive over rough, pockmarked roads that put more stress on the shock absorbers, then you will probably need to replace them more often than if you drive mainly on smooth pavement. Carrying heavy loads also will wear out shocks faster.

All vehicles with a manual transmission will have a friction clutch between the engine and gearbox, allowing the driver to pull away from a standstill and change gears. Clutches are hard wearing, but do need periodic replacement as the clutch wears down.
1, Identify the symptoms of a worn clutch.
Usually this is characterised by the clutch slipping as you apply power — the engine speed will increase greatly when you try to accelerate, even though the clutch pedal is not pressed. Under normal driving, a healthy clutch will 'lock' the engine to the transmission, so its speed should be directly linked to changes in the commercial vehicle speed.
2, Make sure the clutch itself is at fault.
If your vehicle has a hydraulically-operated clutch, eliminate air in the system by bleeding the hydraulic circuit, as you would with the braking system. A cable-operated clutch could be suffering from a seized or jammed cable, preventing the clutch from taking the full torque from the engine parts.
3, Have the clutch replaced as soon as possible.
Clutch replacement is an involved job, requiring removal of the transmission to access the clutch. Unless you are an experienced home mechanic, book your car into a garage to have the work done.

At present, China has become the competitive stage of the world auto parts enterprises .
After the rapid development, China has become one of the most important
overseas markets for multinational companies. Take the passenger car
for example, the multinational companies in China's market share reached
70%, according to their plan, the capacity will be further expanded in
the future. The production of GM, Volkswagen, Nissan in china has more
than 25%, especially GM reached 28.1%, Volkswagen reached 26.8% and
Nissan reached 20.6%. There is no doubt that China has grown into one of
the world's most important car market.
Through auto parts enterprises establish the strategic cooperative relationship with the automobile companies ,
actively follow up and synchronize development and system development,
which lead parts enterprises technological progress. Increase R & D
investment, explore the technical personnel's potential and get rid of
the technical dependency situation. Also can introduce the international
advanced management system and transform the economic growth model.
Internationalization is the only way which makes Chinese auto parts enterprises
bigger and stronger. Besides, according to intervening the exploitation
in advance, promoting the vehicle enterprise technology, establishing
mutual benefit and win long-term cooperative relations, we can withstand
the impact caused by the transnational auto parts market. Through the
introduction of international standards, we can establish the
first-class quality management system, such as QS9000, ISO9000, but we
should strictly implement to ensure the stability and reliability of
product quality. The international market talent team can also be
introduced and established. Training competitive incentive mechanism,
strengthening the information technology and the establishment of a high
efficiency, fast, accurate, stable and safe modern information
management system, these can establish and improve the information
network platform, also can timely collect and grasp the market dynamics
both at home and abroad.
So-called internationalization, the
product, performance, quality and service should be achieve
international general standards and meet the requirements of foreign
markets. To expand the overseas market, we not only can set up factories
but also can establish the service system in foreign countries. This is
the only way we can firm internationalization. At present, whether China's auto parts industry
or vehicle industry, compared with the international advanced level
there is a certain distance, so Chinese domestic companies have to
establish a firm confidence that we can stand on the international stage
in the near future. In addition the future road of the
internationalization will be more steady and wider.
Adhere to
international road, we must adhere to the technology, management and
model innovation. Automotive industry as a pillar industry of the
national economy, to grow stronger is a top priority. Our number of the auto parts company
is gradually increasing, but the ability is much worse. So that we can
enter the international market, the domestic enterprises must undergo
rapid promotion in management, quality and technology.
