Outer Limits 4x4 Board

As far as im aware 40 front and rear diffs, 60 front and rear diffs and 80 rear diffs are all the same!?!

But I sold a set of diff gears (r and p, not a complete center) out of a 40 series front and the guy who wanted to put them into the rear of an 80 said the splines are different.

Is it just that entire centers can be swapped - but the individual parts internally are different?

or

Did later 80's come out with a different center?

or

is the guy a tard?

Thanks

They arent the same...
80 series have a smaller high pinion front diff (people keep saying its hilux, but its not!!!!) and 60 series have the same size front to rear. The rears between 60 and 80 are the same though.

Early 40 gear had coarse spline pinions.. This is the only spline on a diff gearset.

If you only sold him ring and pinion, he has no splines for the axles, though he would have a spline on the pinion where the flange attaches for the tailshaft..... so the question is, what splines is he referring to?

what splines does he mean is the frst thing i would find out.

Also the gears ratios are different between 40/60/75 and 80 series.

the difference is that minut that it makes no difference, although if it is going into a fulltime 4x4 80 i guess it might.

If you read his post properly he did not mention 80 front.

Yeah you are right, it should be sweet as balls. Early pinions had a coarse spline too, and a different flange bolt pattern.

ok, thanks, its the pinion spline not the axle splines.

I found another flange for the pinion which should sort it out.

Thanks
for the help.

Also beware, there are some different spacings on the bolt holes for the tailshaft flange..... check them first, I've been caught before..

Heaps of different flange patterns, TWO major types and you can get a universal flange to suit coarse or fine spline pinions.
