Drive Shaft | How to Detect the Quality

Most parts of the drive shaft are exposed outside, and its technical status can be visually detected and judged. When testing, stop, put the gearbox in neutral and release the parking brake, and test as follows:


Drive Shaft


①Check the connection screw between flange and flange fork and whether the fixing bolts of middle bearing bracket are loose.


② Shake the front flange fork of the intermediate drive shaft radially to check the locking condition of the flange nut. If the radial clearance is large, it indicates that the rear bearing of the second shaft is damaged or loose.


③Shake the rear flange of the intermediate drive shaft radially to detect whether the flange nut is loose. If the radial clearance is large, it means that the middle bearing is worn loose or the backing ring is worn.


④Check the tightening condition of the cleats, shake the universal joint fork to check whether each universal joint is loose.


⑤Check whether the drive shaft is bent, whether the balance weight has fallen off, whether the universal joint forks at both ends are in a plane, and whether the three universal joints conform to the principle of constant velocity arrangement.


⑥ Shake the rear flange fork of the drive shaft radially to check if the flange nut is loose. If the radial clearance and the free rotation angle of the drive shaft are too large, the problem lies in the rear axle.


⑦When the location of the noise is not easy to distinguish, the car should be parked on the trench, the rear axle should be erected, and the rear axle should be started on the spot to make the rear axle rotate in each gear position. Check the noise in the trench and touch the place where the noise is made. If you touch the vibration that matches the sound frequency, it is where the noise is.


We have first-class production line and strict management system.
