Postby 4x4SWANNY » Wed May 25, 2011 5:12 pm

This topic has prob been done to death but new to me...Has anyone tried it on a long wheel base ubs69..
By the looks on mine would just have to grind out front lip on diff for crown wheel to slot into housing.
Oh well, can some one hook up the winch i cant open my door !!!!!!!!!

Are you talking about revolving the diff head around in the diff housing (upside down)?
Wouldn't it go backwards?

No it wont run backwards, it will just run on the reverse side of the gears.

On a short wheel base it would give the prop shaft far less off an angle... And truely mud i dont see a point to it ...Was just curious to see if anyone had tried it..Looked today at my spare diff and the holes would all have to be redrilled on diff flange...
Pass next idea lol..

It cant go backwards.. You would have to spin the prop shaft backwards....You would how ever have to run alot more diff oil to keep the pinion bearings lubed...

By turning the center over you are driving from the top of the wheel.
