Hey guys, I am need of a bit of help. I just made a move over from the Jeep world to the Chevy side. I am trying to identify my front diff's - I just got a 1986 4x4 Sub. It looks like a D44 but has GM 11 stamped on the case. What is this thing? The rear is a GM 12bolt.
Thanks for the help
I hear you, it does have ears! :-)
It is a 1/2 Burb and I actually had been looking at the pics on Colorado K5 Axle Identification Chart and they did not show those ears. I found a pic on the www.drivetrainsuperstores.com site and it showed those ears you refered to.
I guess the guy before the guy I bought it from changed out the rear for a 12 bolt (GM is so nive to name these by the number of bolts) too bad he did not go with the 14.
Thanks again for the help
I included a pic of the GM 10bolt to help others with future references
Well, for that generation of truck I don't think they ever made a 14SF with 6 lugs. I can't ever remember seeing one anyway. So therefore, if they did swap it in it would've had 14mm lugnuts instead of 7/16" and they would've had to move the shock mounts and spring perches.
You should've found this in the archives as well. I'm sure I must've posted it here before.
