What are the steps for rear axle disassembly and installation?
2 Answers
Lift and securely support the vehicle. Remove the rear suspension arm bolts. Remove the outer universal joint fixing bolts and cover. Slide the half-shaft together to remove it. Check the universal joint assembly for wear or damage, replace if necessary. Install the new universal joint suspension arm, tightening the bolts to the specified torque.
I disassembled the rear axle myself two years ago when repairing my car, due to a differential noise issue. The process must be followed step by step: First, safety preparations are essential—secure the vehicle properly with a jack and stands, and disconnect the battery negative terminal to prevent short circuits. Remove the wheels, brake discs, and shock absorbers, then disconnect the driveshaft linkage. Gradually loosen the rear axle mounting bolts, being careful not to damage the bearings or suspension. After removing the rear axle, clean off old grease and debris with a degreaser, and inspect the gears for wear. If cracks are found, replace the components. During reassembly, apply fresh lubricant first, ensure all parts are aligned, and tighten the bolts to the manufacturer's specified torque. Finally, reassemble the brakes and shock absorbers, then start the car and test for smoothness at low speeds. The entire process is time-consuming, so wearing anti-slip gloves and safety glasses is recommended. If you're not experienced, it's best to seek help from a professional repair shop rather than forcing it.
