Is it my Front or Rear Differential or both?
1999 Chevy Tahoe 4x4. After a series of high
pitched whirling I experience my differential
go out on the highway. I pull over and put it
in park and try drive again and it just revs
with cracking sounds...While Pulling it
around the corner to a Family members
house (4wheels down in neutral) I still hear
cracking noises (Bearings shot?) My
question is has my rear diff or front diff gone
out or maybe both?
