Detailed Description

This GKN Loebro CV axle shaft, part number 304621, is built for front right installation on select BMW xi models. The axle uses a plunging inboard joint and a fixed ball outboard joint to match the drivetrain geometry required by 325xi and 330xi vehicles. With 27 inboard splines, 30 outboard splines, and a compressed length of 35.629, it is specified for accurate fitment and smooth power transfer in all-wheel-drive front axle applications.

Common Problems This Part Can Address

• Clicking or popping from a worn front CV joint during turns
• Vibration or shudder from a damaged axle shaft
• Grease leakage from a failing CV boot or joint assembly
• Uneven driveline operation under acceleration
• Noise from spline wear or joint wear at the front right corner

Installation Notes and Tips

Verify front right fitment by year, model, and spline count before installation. Confirm axle nut thread size M27x1.5 and compare the compressed length to the removed shaft. Inspect hub, transmission-side sealing surfaces, and related hardware for wear before final assembly. Proper torque procedures and alignment checks help ensure correct driveline operation after replacement.
