REPAIR AND MAINTENANCE Differential (axle) CAR

• Real Axle Housing, this section can be regarded as the foundation of heavy cargo car, because of its rear wheel section, especially on the charge car or minibus. At the mini buses are rarely found these parts bent, crooked if it happens then it is caused by the collision. In this section the truck often found swelling. This is caused by a charge in excess capacitance. Crooked this section will damage the axle axle even damage the teeth. To avoid this it is in giving the charge on the car should consider the condition of a rear. If a differential housing until it touches the touch, the risk is very large crooked.

• Gaskets. As part of the axle to prevent leakage of oil is also an important part. If the leak will result in tooth axle lubrication imperfect tail damage to the axle gear. Use a standard gasket or drawing paper, do not use thick cardboard.

• Differential Carrier. Differential tooth attached to this section. To reset or replacement of part of this new gear is released from the differential housing. Once cleansed of remnants of oil and then mounted on tanggem. To unload and set up this section need specific instructions.

• Differential Ring Gear and Drive pinion gear kit. Named for the repair kit because the differential enough to replace these parts. On some cars a lot of counterfeit goods. The price difference far. Although not all counterfeit goods is bad but you need to be careful to buy this kit. Fuss also generally store would not accept back teeth that have been tried, although the setting is still sound. Then it is better to buy the original. For more secure again, down to the garage your vehicle dealer because they will pair the original and provide a guarantee for a certain period of time or miles. Since the price differential kit is expensive then it is highly advised not easy to decide to dismantle the symptoms when you hear a sound. To ensure better you try to run a car on a flat road. At speeds of 40 served until 80 kilometers / hour, note; if the teeth on each axle is damaged then there is the sound speed and time of releasing the gas pedal the sound of the first models appeared lost and the second sound model. The sound can also be caused by damage to the bearing surface of the wheels and tires. Noise caused by both this section and is clearly another at speeds 80 to 100 km / h transmission gear you free.

It is important before the dismantling of this section, conduct thorough research. Lack of experience could lead to the restoration effort does not meet the desired results. Then the examination of the causes of noise such as tire and wheel bearings as well as the sound of the exhaust needs to be examined one by one. 

• Part of this carrier differential to fasten one side of the bearing ring gear. Screw in this section allows a mechanic to set the tangent plane with the drive pinion. Adjustment results from this section can not directly be because if you look good field that does not intersect the adjustment must be repeated from the first again to remove the drive shaft. It's just a brief overview of the complexity of differential tuning cars.

• Both fasten the drive shaft bearings should be replaced if there is time to disassemble the dots appear black or blackish in color is due to continue to use bearings such good results that have been setting will change to loose again and accelerate the wear of the bearing material, the result would make the drive shaft forward and backward and damaging the tangent plane of the ring gear with the drive gear.

• Oil seals are located at the end of this function of the differential housing does not prevent the oil runs out. If you find around these parts are wet due to seepage of oil should immediately replace the new seal. Remove the propeller shaft and loosen the nuts that fasten the drive gear. To remove this nut should use the torque wrench. Consider for the moment need to be loosened how kg/cm2. It is important for reassembling. Hardness should be the same. Because of different magnitude was different then the lock violence. If you are in doubt you should ask the car dealer. Pairing this seal should sit well and flat. Clean the carrier so that the time differential seal leak did not enter. May also use a little liquid gasket on the outer side of the seal. In the old car, it can happen that although the installation procedure is correct but the oil still leaking. Next need to pay attention to the Universal Joint Flange.

• Universal joint flange is the part that went round the propeller shaft to the differential besides that it also functions as a cap so that oil does not come out. This section is always rotating shaft in accordance with proper rotation. Although made of steel it is also eaten by the seals wear out a tip mounted on a differential carrier. This is why oil continues to come out even after replacing with new seals. To cope with this condition usually releases per the existing mechanic to seal and make it shorter. At first glance can be overcome but not completely, because it forced the rubber match your part that had shrunk. The safest course of action by replacing the new flange. The author recommends doing two actions: First, install the new seal is not exactly on the old seal holder. That is shifted forward or backward about 1 mm. Both sides of the flange is made of 1 mm shorter as well, or put a ring of steel as thick as 1 mm (must ring steel) at the end. This action is also intended to shift the worn area is no longer in contact with the seal. With this action better results.

• Differential pinion gear or a mechanic called satellites. These teeth are arranged on the speed cornering as the car left and right wheels can be mutually adjust the self. Wheels on the angle of rotation must be slower than the round the outside. Wear on these teeth usually cause symptoms in a car when you leave or while walking if you want to add speed or slow down any noise due to looseness. This could be caused by worn out as his or specer pinion. Mechanic is usually overcome by replacing as new and give a thicker layer on its side gear.

• Fastening the drive shaft nut is often overlooked. It did not occur to check if still buttoned properly, especially on the car load. If the nut is loose will cause the drive shaft to move forward and backward. As a result of this movement then there is change in the field of allusions to the ring gear with the drive shaft. At first will occur the hum and someday even the teeth can fall out in the differential. Highly recommended for large trucks every 3 to 6 months to check the violence of this nut and every year on light vehicles. Differential well maintained can last a long time by itself does not need to drain your pockets.
