The biggest problem with the Freelander was the Viscous couple which would fail leaving you without 4wd, and you wouldn't know until you got stuck. as you say not to worry just remove it and run the car as a 2wd. Problem solved. A more serious issue was the Rover K series head bolts stretching and making the engine into a nice boat anchor so the 4wd system was the least of your worries. and the Freelander was definitely a rover group product conceived in the 80s well before the BMW take over. I remember the test mule being an austin maestro van.MK1 Freelander...to be fair they might do it to mk2s but they were the originals were both common and largely worthless so if the prop shaft bearings went most just removed the prop shaft.
Obviously as per 99.9% of 4wds the 4x4 was doing nothing most of the time anyway so if anything it at least improved fuel economy.
Then the Freelander 2 was designed and released under Ford's ownership.. with ford Engines.
So no BMW freelanders
