Bolt size to undo the flange off the front of a g-series diff

[fixeruperer]

yeh there's that collapsible spacer between the two pinion bearings, but you'll be fine if you mark the nut as i said a few posts up.

If you remove that nut you will have to fit a new crush tube. Otherwise there is no bearing preload and your diff will last a few months only.

That specific to this diff, or a general thing?

I changed the flange on my old T series (and had to use an oxy to get the stupid thing off) - and did nothing bar swap the flanges, think might have got a new nut. Then drove around on it for 18mths with no problems?

with all collapsible spacers to set preload .

your ment to change it but if your carefull and mark it and put it back where it came off you dont have to.
done it many times.

Interesting..

Absolutley NOTHING has come out of mine? Bar some oil...

I took off the nut, then there was one thick washer type thing, and the splined flange arrangement, then nothing else?

Although the input shaft of the diff does now flop around because it's not supported.

Nothing else has come out though?

30mm nut- flange - seal - big washer - bearing and bearingcup - collapsible spacer - shim - bearing cup and bearing -pinion teeth.

the collapsible spacer is about 3" long and sits on the pinion near the teeth side of it, youd have to take the outer pinion bearing out to see it.

mine went 30mm nut, flange, big washer. that's it.
unless I'm missing something?

All the stuff that fixeruperer is talking about is inside the diff, on the other side of the flange seal.
