No rear drive

[Cleptomaniac]

Ok soooo I was pulling tree stumps where the tornado went threw and then their was a loud bang and I lost power to my rear axel. So i thought it was the rear axel and drove home in 4wheel drive with the front axle. Now im at home and was thinking that i would swap the axle out but the transfer is not putting out any power to the rear wheels. So my question is anyone know what may b the problem? I drained the oil in the transfer case and looked in no metal peices! Any help would be great!

Do you have the air or sprag transfer? Sounds like it is time to replace it. I have a spare sprag if you need one.

Brown's Military Surplus in Binger should have an airshift unit.

It is a air operated. And i was just at Browns yesterday Any idea what they should run?

.................... the transfer is not putting out any power to the rear wheels.........

.... but still turns the front... and you did drive it home and there were no abnormal noises coming from the TC...? Ummm, thats hard to believe.
What exactly did you do to determine its the TC?
Did you already disconnect the propeller shaft at the rear output? Does it spin free while in gear? Does the E-brake drum feel loose, only held in place by the brake shoes and lever?

I guess nothing is broken there... you just snapped a rear axle shaft!
Its easy to confirm: put in gear, jack up one (any) side of the rear axle and most probably you can turn the wheel with the propeller shaft standing still ...

Just pull the axles, you will find one broke

Yea I broke a axle shaft but i have anouther axle. The transfer is the prob I drove it home in 4 wheel drive with the fronts pulling. Pulled the rear drive shaft and the rear output just spins freely. Like maby I sheared off a pin or something. Did that on a Jeep tranny once.
Well guess ill pull it and let you guys know what I find.

Please try to use a better thread title than HELP. Many people will not look at threads with titles that dont give a hint of it's topic. Also, later in a search it will be ignored.

You will definitely get better results when you put a bit more thought into your title.

.............. Pulled the rear drive shaft and the rear output just spins freely. Like maby I sheared off a pin or something. ....................

There is no pin... The large (33T) gear is firmly pressed onto the shaft and takes a woodruf key. If that key had sheared and the gear really was spinning on the shaft there would be no traction to the front either.

GT,
Could he have broke the rear yoke ( split the collar) and in turn pulled the splines, I have seen that happen on other trucks though not MVs

 

[ODdave]

Im voting the output shaft is sheared where the splines start, just behind the yoke.....

If this be the case would not the nub be loose and it, the yoke, ect just fall down because this AFTER the bearing retainer

Park brake shoes would hold it.

Might have spun the splines out of it, or poped the ring and pinion on the front tandem.

The truck is totalled. You should give it to me.

 

[gringeltaube]

If that shaft really snapped, inside or just rearward of the bearing the brake drum would be dragging against the E-brake shoes and not spin freely.

On the other hand I've never seen a companion flange split open or its splines ripped off.
Most probably the shaft's splined end would twist off before that. But everything is possible...

If it was that loose, you would think he would see it flopping around when he turned the shaft ????, if that was the case, it would have made one HE!! of a sound going down the road

OK point taken
If you were in the cab of the dead truck with the motor running, could you have head any noise???

OP, please let us know what you found

Wouldn't raising both rear tires and attempting to spin one side by hand diagnose the rear axle issue? When you lift both rear tires off the ground in a non-double reduction axle the opposite tire turns either the same direction or the opposite (depending upon whether or not it has a "locker"). I've not attempted it on a DD so I can not say first hand what should happen.

If one where to lift the rear of the truck in the air and rotate one side and the opposite did not move then your answer is clear.

A full floater axle that is broken can easily be run with no other symptoms, less the lack of pull from that axle. I've driven them home the same way.

On a side note the pull axle may not hold up to continued full duty use. Ask me how I know!!

No more/less noise than the op would, ditto on the report of findings!
