Damage, wear and tear, deformation and loss of dynamic balance of drive shaft parts will cause the car to produce strange noises and vibrations while traveling, and in serious cases, will lead to damage to related parts. Automobile driving, in the start or rapid acceleration when the "geden" sound, and obviously show the feeling of loose parts, if not the drive axle on the transmission gear loose is obviously drive shaft parts loose. Loose parts are nothing more than cross bearings or steel bowls and flange forks of universal joints, splined shafts and splined bushings of expansion sleeves. Generally speaking, the opening of the cross shaft and bearing should not exceed 0.13mm, and the engagement clearance of the expansion spline shaft and spline sleeve should not be greater than 0.3mm. more than the use should be repaired or replaced.
Automobile driving if the chassis appears "buzzing" sound, and the higher the driving speed, the louder the sound. This is generally due to the universal joint cross shaft and bearing wear and loosening, drive shaft intermediate bearing wear, intermediate rubber bearing damage or hanger loosening, or due to the hanger fixed position is not right.
When the 6×4 vehicle makes occasional knocking noises during heavy loads, especially during bumpy driving, attention should be paid to checking whether the rear axle balance shaft is dislocated and interfering with the drive shaft. If the rattling sound is large with the increase in speed and accompanied by shaking, this is generally due to the loss of balance of the drive shaft. This vibration is clearly felt in the cab. The unbalance of the driveshaft should be less than 100 grams centimeters.
Severe driveshaft unbalance failures can lead to damage to related components. Cracks in the clutch housing and fatigue damage to the intermediate rubber bearing are common.
The installation of the drive shaft intermediate hanger is very important in maintenance. If the hanger is not installed properly, it can increase the operating resistance and noise of the driveshaft, leading to early damage to the bearing. When reinstalling the hanger, first do not tighten the hanger fixing bolts, use a jack to support the car's drive wheels off the ground, put it in low gear, slowly rotate the drive shaft so that the drive shaft and the hanger are automatically squared, and then tighten the hanger fixing bolts.
