Removing drive shaft for better fuel economy..

It should work good going downhill. The new automatic transmission go into neutral. So it just as good as removing drive axles. Plus you can still go uphill. LoL

 

Yeah, no. Pull all 4 axles though and fuel economy skyrockets.

 

Give it a try...Then Report back ...
I'll stick with whats been been working

 

I thought this was a joke question. I see now he just wants to remove the rear drive axle and make it a 6x2 truck.

 

My question is what happens when you need that 6x4? You put it on? You don’t know what conditions the roads are where your going. One tow bill will literally offset the fuel savings for the decade.

 

Yeah you can, but any fuel mileage gain will be eaten up in increased tire wear on front axle. As well as increased wear in
Front diff.

 

You need to thoroughly study how a tandem axle setup works.
Power is applied equally to all 4 wheel ends under normal situations.
When any one wheel end loses traction all power goes to that wheel.
If you lock your power divider in, then power is applied to the spinning wheel and also to the other axle.
Only if you have full lockers on front and rear can you get power to all position when one or more wheels loses traction.

 

Pull the driveshaft, pull the axles. Make caps to bolt onto hubs to keep oil in, crap out.
Have fun when winter weather gets here.

 

Your close. The power divider does nothing for the differential. It merely locks the front to the back. The 1 set that was spinning will still spin. In most situations the other axle once locked in will have better traction. An open differential is still an open differential. It takes a diff lock to put power to the wheel opposite the one that is spinning.




Save your money or buy a truck that’s already set up that way. You will not gain enough to ever see a difference
