swapping pinion??? (1 Viewer)

[frenchman]

hi,

still trying to rebuild the axels out of my 78'40.....

anyway, while dismantling and cleaning all the parts, I notice the the spline on the rear pinion have some whear marks on them.......and the front one, since there not use all the time*looks like news,......

so here is the question: Is it a good idea to swap the front and rear pinion? As it been done.

for the record, both diff are received new bearings....every one of them! So all preload and backlash will need to be reset anyway..

so what you gurus think about that!

thanks

Yves

Just swap the thirds. Don't swap the pinions.. Those are kinda matched to the ring gear.

X2!!!



I know people that have put a different pinion into a housing to get out of the woods when one has broke on the trail...but it is not something that you would do to a gear set that you wanted to last for any length of time.


Good luck!

swap center chunk. Everthing else is the same. Just remember c clips are in back.

Yes, you can swap front and rear third members (not on an 80 though)

The fronts have very few miles on them vs. the rear...

The fronts have very few miles on them vs. the rear...

provided the vehicle has or had lock outs and not drive flanges....
