Hi guys,
Need some immediate help in identification and location of a new or used axle. Truck got a little sideways on him and he bent the drivers side axle when it hit a curb. Rim is in no better shape but that's the easy part to replace. Rear end is a limited slip, 14 bolt unit with 3.73's. If anyone can look up the VIN and put an exact ID on the axle, I'd appreciate it. VIN number is 1GCGC29K2SE112679.

Thanks in advance,
TT

Wow he really must of smacked the curb hard to bend the axle. Is it a full-floatong or semi?

I honestly don't know. That's why I posted the VIN hoping someone could look up the exact unit. Why did you ask if one was full floating or semi? I consider myself a pretty decent mechanic but will admit I've never had an axle apart outside of changing the fluids.

<DT>G80 Rear Axle: Positraction<DT>GT4 Rear Axle: 3.73 Ratio<DT> <DT>This is all I can get from the VIN, but you already knew that. Maybe a parts guy can help more.

Thanks GMCSID,
That's more than I had. I bet he wishes the G80 code was the same as my '03 with the locker.):h ):h ):h

I know that a good used one goes for about $1500-$2100 so a cheaper recourse might be to have the axle straightened. We do this when the truck is too new to go used but the ins. won't cover the cost of replacment $2100 fo just the housing. BTW we use Oceanside Driveshaft they're not cheap , but we've had no come backs, hope this helps.

A "semi floater" will not have the large hub sticking out of the center of the wheel like our 2500/3500 HD's have. The flange that the rear wheel bolts to will be flat.

A "full floater" will have the large hub that sticks out of the center of the wheel about 4 to 5 inches. It's called a "full floater" because you can actually remove the drive axle from the hub and the wheel will stay on the truck and you can roll the truck around. The drive axle does not support the weight of the truck, it only turns the hub. The hub supports the weight of the truck with a seperate set of bearings and a stubshaft from the rear end housing.

I've got a semi floater 14 bolt with 3:73 gears (no posi) that you can have for $400, but the only problem is that it is in Oklahoma city.

If your son bent the axle then you probably have a "semi floater" and have bent the axle at the point where it meets the flange the wheel attaches to. As described above, the axle on a semi floater serves double duty and has to support the weight of the truck and turn (drive) the rear wheels. It would also take the brunt of the impact in a side slide you described.

If you bent an axle on a full floater, then I would imagine that the housing would be cracked also, and possible frame damage to the truck. Those things can take a considerable amount of abuse and it would take one hell of an impact to bend one of them.

Let us know which one you have.

Exactly what Searay said.

Does it wobble when you spin it? Do you have the wheel off? Does it turn free?
Like searay said,Wheel might give but those axles are tough.

I believe his is a semi floater if I remember correctly. It's been a while since I've looked at it. Got the call from him last night and will be seeing it today.

Will have to look into having it straightened out. Didn't know the driveshaft shops had that capability.

Wobbles to the point that the rear brake on that side starting smoking on him when he pulled off the road. Starting to also think that it might be just the axle and not the rim. The rims are aftermarket units that are pretty thick.

Thanks again guys. I'll keep everyone posted on the progress and what we find out.

You can pick up another corp14 FF around $200.

If the axle is a semi floater(easy to tell, looks just like a 1/2 ton flange type, just with 8 studs) Just replace the axle shaft. Remove cover, remove cross pin, remove brake drum, push axle shaft in slightly, about 1/4 inch, drop out c-clip and remove axle shaft. This type of axle is a 14 bolt semi floater with 9.5 inch ring gear. Used axle shaft should be available for under 100.00

If the axle is a full floater, with wheel removed there will be a hub with eight bolts that hold the axle shaft to the hub. I have never seen one of these bend to where the wheel wobbles, usually the housing tube will bend. Let us know which one he has.:grd:
