Instructions for using automotive ball cage bearings

Automobile ball cage bearings (constant velocity universal joints) are the core transmission components that connect the gearbox and the wheels. Their usage should revolve around three core steps: installation, maintenance, and troubleshooting. The specific steps are as follows:

1. Installation method: Ensure power transmission stability

Preparation: Park the vehicle on a level ground, lift it with a jack, and place wooden blocks to prevent sliding. Prepare wrenches, pliers, professional ball cage bearing disassembly/installation tools, as well as new dust covers, lubricating grease, and snap rings.

Disassemble the old bearing, remove the dust cover, and use professional tools to remove the ball cage bearing from the ball cage sleeve to avoid damaging the ball cage sleeve or bearing.

. Clean the cage cover and installation position to ensure that there is no dirt, burrs, or oil stains.

Install a new bearing and apply an appropriate amount of lubricating grease to the ball cage sleeve and bearing raceway. Install the new bearing into the ball cage sleeve, fix it with professional tools, and ensure a tight fit.

.

Install the dust cover and secure it firmly with a snap ring or tie ring to prevent foreign objects from entering.

. Acceptance testing checks whether the installation position is correct and whether the dust cover is sealed. Start the vehicle for a test drive and confirm that there are no abnormal noises, vibrations, or power interruptions.

2. Maintenance points: Extend service life

Regularly check the lubrication. Check the condition of the lubricating grease every 20000 kilometers. If it is found to be dry or deteriorated, it should be replenished or replaced in a timely manner.

. Use specialized ball cage grease (such as G6 type) to avoid bearing damage caused by ordinary lubricating oil.

Dust cover protection: Regularly check the dust cover for damage, aging, or oil leakage, and replace it immediately if any problems are found.

. When installing the dust cover, it is necessary to inflate and balance the pressure to prevent creases that may cause seal failure during driving.

Avoid extreme working conditions, reduce long-term rapid acceleration, sudden braking, or bumpy road driving, and lower bearing loads.

. Control the speed when turning to avoid excessive lateral force on the outer ball cage.

III. Fault Handling: Ensuring Driving Safety

Common Fault Phenomena Abnormal Noise: When driving in a straight line, sudden acceleration/fuel withdrawal produces a "click" sound, and the abnormal noise intensifies when turning.

.

Power interruption: Severe wear and tear causes power transmission to be obstructed, resulting in weak acceleration of the vehicle.

.

Steering shake: The clearance between the ball cage bearings is too large or damaged, causing the steering wheel to shake.

. Troubleshooting steps: Check the dust cover: If it is damaged, replace it immediately and check if the bearing has water or dust.

Test bearing clearance: Use your hand to push the ball cage axially. If it becomes loose or stuck, replace the bearing.

. Check the lubricating grease: If the grease deteriorates or is missing, it needs to be cleaned and refilled.

Replacement suggestion: When the bearings show wear, cracks, or abnormal noise, the inner and outer ball cage bearings must be replaced in pairs to ensure balanced power transmission.

.

Choose original or branded accessories to avoid early failure caused by the use of inferior bearings.

IV. Key precautions

Professionalism of installation tools: Special tools must be used to disassemble/install bearings to avoid violent operations that may cause component deformation.

.

Pre tightening torque control: When installing the retaining spring or bolt, it is necessary to tighten it to the standard torque to prevent loosening or over tightening.

. Environmental adaptability: If the vehicle is driven in a humid or high-temperature environment for a long time, the maintenance cycle should be shortened and the dust cover inspection should be strengthened.
