My front diff has been making some noise recently. ST165, 3rd day now. It just got really cold, low single digits. And from the first day when it was -2 in the morning my diff, and/or trans started making whining noise, kinda like a bad bearing.
I only drive 4 miles to and from work, about 15 minutes. I dont know if the trans had enough time to reach operating temp.
I have isolated this noise to either the differential, or the trans output shaft. It occurs with the engine off, and the clutch depressed.
The rear wheels are still getting power, I can spin them, and I can see the drive shaft spin under load, so I dont think anything is broken. (No handbrake, so I can see the shaft out of the mount hole)
Could it be a bad bearing on the output shaft? That's always spinning right?
What if I put the car in FWD mode, does that physically uncouple the diff?
What can I do to narrow down the noise?
