i bought a 79 f350 4x4 a few months ago and have been working on it ever sense . The rear drive shaft yoke is to the back hooked to the dana60.

The truck has 6 inch lift.

1 why would the shaft be in this way?
2 should i turn it around?
3 To take care of this properly do i need a longer shaft ?
4 is it ok to run it this way ?
THANK`S

 

Lots of reasons come to mind as to why the drive shaft could be in backwards.

I bet if you gave it a bit of thought and re-read your questions you could answer them all yourself.

1)Maybe the last person to install the shaft screwed up and got it backwards. Maybe he didn't know any different. Maybe he didn't care. Maybe there are differences in the u-joints and that was the only way it would fit.

2) If you know it is in wrong why wouldn't you put it in correctly?

3) If the drive shaft is long enough now I bet it will be long enough when you turn it around. If it is too short now it will most likely be too short after you swap ends. A 6" lift will typically require a longer driveshaft. Whether your drive shaft is stock or lengthened wasn't mentioned.

4) A shaft with the spline/yoke to the rear is typically more prone to vibration and u-joint wear than one with the spline/yoke forward.

 

thanks fot the help, i just started taking a closer look at the drive system i have been doing other things to the truck. i was looking for advise and opinions before i pulled it out . thanks
