Hi just getting traveller from extensive welding at last.Niticed leaks on rear axle for which I found part DIF107.However unsure of number for the gasket that joins the diff to the axle.i can tell its firist sized as it is on the end of the diff but unsure of its number.can someone advise please

You only need quantity one DIF107 gasket.
The gasket fits between the diff housing and the axle casing.

Thank you so would it be there is no gasket between where the diff connects the axle as there is a joint that looks wet.

Does this help, gasket highlighted.

It does thank you.i have been informed that it is a diff seal with a spring on it behind the coupling unit that we would also need to change would need the part number if possible so I ca order together.i think that's all I would need to do the job unless you can advise other parts i would be advised to change at the same time thsnks

I have looked a diff opinion seal I guess is what I am after.can you advise on which please for 1971 traveller

If the leak isn’t bad I would leave it as the replacement of the seal can go wrong:-

The pinion nut sets the bearing preload by the use of a single use crushable spacer.
A workaround if you are only changing the seal would be to mark the nut to the flange so it can be tightened to the exact same position, not forgetting to mark the flange to the pinion shaft to get it on the same splines.
The leak could also be due to pitting on the shaft where the lip of the seal runs, I think a shaft sleeve is available as a repair.
You will need to make something to stop the flange turning, easily done with some bar as an impact wrench can’t be used for tightening the nut.

Thank you I have been put off now.Might just do the gasket .Best wishes

Can I ask is it a simple swap with the gasket.just undoing the bolts at both parts and changing over.please advise.

You have to remove both half-shafts before you can remove the diff assy.
Uncouple the prop-shaft from the diff - align mark both diff and prop-shaft flanges before uncoupling them. Reassemble with the marks re-aligned.
Remove the ring of diff housing nuts/washers and remove the diff assy from the axle casing. You may have to disengage the brake pipe three way coupler from the diff casing nose.
Before you do anything make sure that you can remove the filler plug.

Great advice as ever
