Installation Notes and Tips

Verify the vehicle’s rear position, spline count, axle nut thread size, and inboard mounting pattern before installation. Confirm the BMW model, year, and notes such as 27mm or production-date requirements to match the original axle configuration. Inspect related seals, hub surfaces, and mounting points during service so the replacement axle seats correctly and operates smoothly.
