Hi all,
Have a 1988 740 turbo wagon with m46 and type 3 driveshaft.
I recently changed the center bearing and carrier along with 2 u-joints on my driveshaft. After taking it down the freeway at around 75mph I can hear what sounds like the center bearing is whining at a somewhat high pitch.
The carrier bolts to the crossmember and can be moved front to back an inch or so. I installed the new one towards the front of the crossmember and pretty sure the old was was installed towards the back.
My question: can this probably incorrect installation cause the whining I hear?
Thank you for any suggestions.
