Thread: Leaking front diff

It could have possibly un-seated the pinion seal causing it to leak

TIM.

How bad is the leak, is it gushing or just weeping. Normally they just start to weep. I just replaced my front one when I set up the crown wheel and pinion again. They are dead easy to replace, undo 4 bolts on the prop shaft, then one more bolt and your there. Hold the flange with a stillton, makes the bolt easy to undo.

Thanks for the info.

It is a weep, I come out to the car and there is a patch on driveway around 50mm to 75mm diameter.

Hopefully the insurance assessor agrees that its the result of the accident.

How does holding a flange with a piece of cheese make it easy to undo?

LOL hey rover axles are made of cheese and they do the job just fine

OK whatever else you call it, a plumbing fitting screw in tool job thing.

CHEESE MMMMMMMMMMMMMM........MMMMMMMMMMM

I suspect you meant "Stillson", although, that being a specific type, pipe wrench may have been more appropriate - unless it really was a Stillson pipe wrench?

Hi there,
My TD5 S2 had a weeping leak on the front diff and I discovered that the level plug/filler hole is made of soft plastic and not cheese or solid brass as on my series one 1952.
The soft black plug was only finger tight so I tightened it up with a large screwdriver blade.The leak then stopped, must have been like that for many months since the last service and oil change.So it pays to check every thing that is done during the service as I now do! If it had been made of Gorgonzola then I might have lost even more oil than I expected?
Incidentally, I now do most of the servicing myself and change the front and rear diff oils, including the transfer box, every year.
I read that the extreme preassure oil is fortified with additives to obtain that condition, and that after time it looses the additives and reverts to ordinary oil.That of course has no place in the internals of crown wheel and pinion differential.
Rapid wear would take place if ordinary oil where to be used. Usually when I change mine, it comes out like dirty black watery like substance and that just reinforces my resolve to make sure that I change it every year,and not once in a blue moon as recommended by the dealers!
