Is it necessary to replace the rear axle rubber bushings?

[Marissa]

It is necessary to replace the rear axle rubber bushings. Although there is no fixed replacement interval for rear axle rubber bushings, they should be replaced when damaged or aged. Worn-out rear axle rubber bushings will fail to provide shock absorption, causing chassis vibration and abnormal noises. Severe vibration may affect driving stability and compromise ride comfort. The rear axle rubber bushing serves as a flexible connecting buffer sleeve between the shaft and housing. Damaged bushings may lead to collisions between shaft components and could potentially cause misalignment between rear wheels and wheel arches, resulting in abnormal tire wear. Replacement method for rear axle rubber bushings: After lifting the vehicle, remove the two rear axle screws and oil pipes. Then use specialized tools for rear axle bushings to extract the old bushing. Apply lubricating grease to the new bushing before installing it. The rear axle refers to the components of the rear drive shaft that transmits power. It consists of two half-axles that can perform differential movement. The rear axle also functions as a device to support and connect the rear wheels. For front-wheel-drive vehicles, the rear axle acts as a trailing axle, serving only a load-bearing purpose. For vehicles where the front axle is not the drive axle, the rear axle becomes the drive axle, performing not only load-bearing functions but also driving, speed reduction, and differential functions.
