I’m gaining more confidence slowly with the X5 on roads I wouldn’t have taken up here before the Quaife diff was in. I’m still not, and won’t go down anything really greasy, but it’s 25 degrees so things are pretty solid.
I chickened out on one approach to this field and went all the way around to the other side as the road didn’t descend through a deep drainage wash. I did head out thru the wash and the x5 blasted right up the snowy hill.
I picked up an odd whistling sound when the car is cold, and only at certain RPMs…my anxiety tells me it’s an output bearings, or cv, etc., but frankly it could be anything, just car noises from a car that only sees the real cold once a year. It actually sounds a bit like alternator whine thru the stereo, but why now!?
