It is recommended not to use bad Connecting rod bearing drive. The connecting rod bearing is a critical component at the bottom of the engine and when it fails, it can lead to serious engine damage.

When these phenomena occur, it may be that your connecting rod bearing has a problem. Engine noise Oil pressure becomes low. Metal particles appear in the oil. Poor engine performance becomes worse. High engine mileage, long service life.

In some engines, the connecting rod bearings can be accessed by removing the oil pan and other components from under the engine. This allows a mechanic to remove the link cover and replace the bearing without having to remove the engine completely.
However, in many cases, the engine needs to be removed to accurately replace the connecting rod bearing. This is because the connecting rod bearings are located inside the engine block and their removal requires access to the crankshaft and connecting rod.

If only one bearing is damaged or worn out, only one connecting rod bearing can be replaced. However, it is generally recommended to replace all link bearings at the same time, even if only one shows signs of wear. Here are some reasons why: If one bearing wears out, the others may not last long either. Replace all bearings at one time to ensure uniform wear and optimal engine performance. High cost performance: the cost of replacing all connecting rod bearings is usually not much higher than replacing one bearing. By replacing all bearings at once, you can save time and money on future repairs. Replacing the connecting rod bearing is a complex process that requires the removal of the engine. A one-time replacement will avoid multiple engine disassembly Replacing all connecting rod bearings can help prevent future engine problems and extend the life of the engine.

If the connecting rod bearing is damaged or worn, it cannot be repaired and must be replaced. The connecting rod bearing itself is a lossy part, so it is not recommended to repair the damaged or worn bearing.
