I did one this afternoon on a 75 series same deal, I had a hoist a rattle gun a seal pick and all the right sockets, it took me 15 minutes.
The same job on the ground without a rattle gun, would take about an hour with a lot of swearing.
Cheers Steve.

G'Day Roooboy,
When you replace that whining rear diff centre you won't have to worry about the leaking pinion seal ;))))

You might want to look at changing the crushable sleeve between the pinion bearing cones. If you dont you may increase the pinion bearing preload too much if you tighten the yoke retaining nut to anywhere near its required torque.

I have used rattle guns for years without a problem, all you do when tightening
the nut back up is back the exhaust on the gun down so it doesn't tighten up to tight.
As for the crush spacer 9 times out of 10 the diff centre has to be removed, and the diff pulled apart to replace it as it cannot be pulled out the the end of the diff, and I am yet to see a rattle gun strong enough to crush the spacer.
Cheers Steve.

Steve all i know is that a simple job cost me an extra $500,and i just passed on what i was told ,in fact the mech who fixed it was good friends with the one who stuffed it(that guy sold his bussiness to go and work in the mines)thats why i couldnt get any money back,but one day when we meet i will ask him if spare me $500 of the $120k he gets a year

Before pulling it apart mark the flange, pinion flange and nut.
After replacing the seal tighten
the nut but don't tighten past the point where your marks line up, if you do you will crush the spacer and put a higher than necessary preload on the bearing which will as has been said require early replacement.
To make it all easier I made a 500 mm long bar from heavy 50 x50 x5 mm angle iron to bolt to the flange to hold it when undoing and tightening the pinion nut. Basically it has two holes to line up with two holes in the flange and a bit cut out to clear the pinion nut sufficiently.
Can supply pics if necesary.
