Replaced left front axle shaft and seal. The cv boot was torn and not sure how long. After reading all the tips/tricks here decided it would be easier, faster and definitely cleaner to replace the entire shaft.

TIP - be sure to have ALL the correct tools and parts before performing this very easy DIY. And never use a pickle-fork/ball joint splitter to pry out the shaft from the differential. You will damage the seal and be running to the local BMW store (which in my case was an hour away) to get a replacement.
