How to Determine if the Drive Shaft Bearing is Faulty?
1 Answers
Here are the methods to determine if the drive shaft is damaged: 1. Damage, wear, deformation, or loss of dynamic balance in the drive shaft can cause abnormal noises and vibrations while driving. 2. During driving, noises may occur when starting or accelerating sharply, accompanied by a feeling of loose components. Below is an analysis of the causes of drive shaft failure: 1. Loose connections (or connecting bolts) at the flange joints of the drive shaft. 2. Loose fixing bolts of the intermediate support bracket of the drive shaft, resulting in excessive clearance between the intermediate support and the intermediate drive shaft journal. 3. Disintegration of the intermediate support bearing of the drive shaft, damage to the bearing raceway, poor bearing lubrication, or excessive wear leading to looseness. 4. Misalignment of the intermediate support bracket installation position, improper adjustment of bearing preload, damage to the rubber spacer ring, or incorrect tightening torque of the intermediate support bracket fixing bolts (either too tight or too loose) causing bracket misalignment, leading to abnormal noises.
