What Rear Will Work?
I decided I would tow my Blazer behind my motorhome on a trip to Florida and NC. To make a long story short, as my wife was driving over a two-lane drawbridge, the rear pinion decided it was done with life and blew a hole in the case. She had to wait about an hour on the now one-lane drawbridge until the tow truck got there. They towed it back to the campground, and I got to work on it there in the sand.
I searched all over Florida for a rear end, but there wasn't anything available, so I pulled out the pinion and spider gears, greased up the bearings, locked the front hubs, and put it in 4wd long enough to get it hooked up to my tow vehicle. So now I've got a FWD Blazer and I'm looking to make it RWD/4WD again. I found someone who has a posi rear end with the same ratio as mine, but it came off a 2wd Suburban. Are the 2WD Suburbans on coils or leafs? What other donor vehicles would be good candidates? It's a 12-bolt with a 3.73 ratio. Thanks. |

Re: What Rear Will Work?
The sub rear should work.It depens on how the burb was originally optioned on springs.Chevy was standard with coils,leafs optional.GMC was the opposite.Your best bet would be a GMC from that era or a Chevy equiped with leafs.That should make it a bolt in.

You can use your axle housing and another 12-bolt's innards if it's coil or 2wd with different spring mounts. Just has to be the same series carrier,which this Suburban is. It sounds like a pinion or carrier bearing gave up the ghost. I've had the pinion nut back off and cause broken ring teeth. But,that was after someone didn't torque it down.

Well he could use his own diff if it didn't have hole in it. He did say "case" and not "cover".
