What in the world is going on!!!

>_>!

oh my god, what?

There were once gears and bits and pieces of a positraction unit in there... All got mangled up and thrown out and ground into a pulp of metal shards

oh... yeah.

want!
you isn't it GT-R...?

Its from a 95 GMC Yukon GT K5 Sport Wagon ;) that's the technical term for it.

oh... ^^ you have GMC in 4WD.

you have a very simmilar Yukon as i do , mine is a a 1998 Youkon GT Sport 4x4 ( 2-door with the Vortec 5700 ) i have 316,000 KMS on min so far. :P

But is it a 5 speed? ;)

you have a manual version ? cool mine has the 4L80E 4-speed auto with OD. What have you got dont to your engine ? ( i have the urge to drop in a LS2 crate motor

Bored 20 over, got a Edelbrock TBI intake manifold and Performer cam, headders and a heavy foot

lol* heavy feet hard driver. :P

i gotta say this is nothing compared to the engine i had to replace looked like i bomb went off inside it nothin could b saved. glad it wasnt my engine =P

Its pushing about 240 hp. Crappy California SMOG laws wont let me use a taller cam.

It could be more than that, I havent taken it to the dino yet. More or less I'm looking for a daily driver with a bit of power. I dont want to suck down the gas to quickly now. Also another thing to concider its a TBI with non vortec heads. If I change the heads... then I can free up lots more power

hah ,nice, I just got in from doing a head gasket on my buddy's Audi, and what do I see on FA? more parts lol

Enjoy the road of repairs! You travel in good company

That is some SERIOUS torque on that. I mean it just fractured and sheared?

As soon as I saw the thumbnail I thought GMC 12 bolt posi :/ The 12 bolts (8.875 ring) are good axles, I have a few sitting around, but the posi unit, along with the 14 bolt (9.5 ring) posi are the worse carriers I've worked with. Nice for a daily driver with mild power, but not much more over that. The stronger option is either a open diff with a Detroit locker (not a mini spool, those snap like twigs) or a good air locker or cable locker. In most cases I see these carriers explode on the highway after some abuse, I dunno why they didn't go during the trial ride, but doing 75 on the high, then boom, usually takes out the housing. I can't remember gmc's name for this diff, torq-tract? Oh well, have fun :)

I need to find a unit that will match my front ratio. It is a 4x4

All I have sitting around is a set of 3.08s and maybe a 3.50ish, not sure. If its a daily driver a strait locker or a minispool would hurt, it eats tires and tend to snap axle shafts and wear out U-joints. The only things that I've seen fix this problem is a air-locker or a Dana 60, but the air-lockers runs $500 and a Dana 60 about $500 to $1000. You can also go with a open diff with a lock right, http://www.summitracing.com/parts/PWT-1921-LR/ I've never used one, but I hear good things about them, it would definitely fix your problem and will take 350 - 450 hp easy with a good set of tires, like 33-12.50-15s, or your yukon probably takes 16's, the axles tend to snap around 400 hp with anything bigger and a low gear like 4.10s. Also might want to look into c-clip eliminators, if you upgrade the diff and snap a axle, the whole shaft will come out at the worse time, usually on a fast turn :/

Yeah... the corporate 8.5"s (or was that a 44?) don't like too much torque. Toss that sucker, install a Dana 60!

Dude, you did the same thing with a stock Yukon, did you really expect that a more powerful one would last all that long?

I think somebody needs add a Dana rear to their birthday wishlist.

Time for some heavy duty Detroit Locker goodness in there.

Yipe! Hmm...might need some crazy glue. ;)

Well, THERE'S your problem.

Nice Just went through that myself lol fun project but gotta be proud
