Since the actuator gear normally lasts 100,000 miles or more and the gear is designed to wear properly with OE sprocket I would only replace with an OE gear. If I had one handy for the next time I wouldn't know where it was if I ever needed it and if it held up for 100,000 miles it would be at least 10 years before I would need to look. I have never heard the E53 becomes rear wheel drive at any speed--fact check. I don't know about yours but mine is 60-40 all the time.
