I just had a bad experience that left the car in a parking lot. I left work early (sick) and was on the way to get some meds when I heard some crazy noise. Sounded like the axle had popped out and was grinding spline to spline while trying to propel the car down the road. I pulled over, called a ride, and haven't been feeling well enough to visit the car today. The last thing the car did was act like the brake was on when I tried to reposition it in the parking spot. The trans fluid was good the day before and the trans has about 12k on a Subaru installed reman unit.
So I have read here and there people mentioning that the front diff shells on them. Without actually looked at the problem I was just wondering what the symptoms of a bad front diff would be. I am too new to Subs with awd to make assumptions. I am curious how the input shaft of the trans and the pump isn’t destroyed if they are part of the diff.
I had been thinking about 4.44's, but don't have the time to deal with something like that. I need a vacation!
