Faults of propeller shaft

• deformation and mechanical damage to the shaft;
• destruction of suspension support;
• Backlash of cross assembly;
• excessive clearance of the propeller shaft split joint;
• Wedge of constant velocity joint;
• Worn or damaged split joints;
• Worn or damaged propeller shaft bearings.

Symptoms of propeller shaft faults

• oil leak;
• knocks and rattle at transmission engagement;
• vehicle vibration while driving;
• background noise at acceleration;
• bad gear shifting.

Causes of propeller shaft faults

• looseness of propeller shaft mountings;
• exceeding the part service life;
• incorrect installation of a shaft;
• poor quality road surface;
• sporty driving and frequent hard acceleration of the vehicle;
• lack of or insufficient amount of lubricant in the system;
• damage to seals;
• dirt and foreign objects in the system;
• unbalance of propeller shaft;
• mismatching of clutches and shaft.

Diagnostics

Independently, you can estimate the visual condition of the item. If there is visible damage to components, you need to ask for a more complete diagnosis at a workshop.

Diagnosis of the propeller shaft should be carried out every 40,000 kilometers. First you need to check the universal joint balance and the amount of lubricant. When using a conventional transmission oil you need to replenish its amount every 10 000-15 000 kilometers using a special syringe.

The average life of a propeller shaft is 300,000 kilometers. However, road conditions and driving style can greatly reduce the shaft operating capacity. Without periodic inspection a propeller shaft may fail after 120,000 kilometers.

Repair and replacement of propeller shaft

Without special tools the propeller shaft cannot be repaired or replaced. The most common breakdown is the shaft imbalance. Rebalancing is performed at each shaft scheduled inspection, because an incorrect position of the shaft in the mechanism may result in accelerated wear of related mechanisms.

It is important to observe the laying, because the wrong position of the propeller shaft can lead to its deformation. The optimum position of the propeller shaft gear angles is between 0-20 Co.

Always replace the propeller shaft after serious mechanical damage, or expiration of its operation life. the part must be replaced only at a service station.
