Rear Transfer Oil Seal

[HarlingtonStraker]

Hi ho,

Have replaced the rear oil seal for the transfer case.

But a little oil still leaks out onto thru the bottom of

the handbrake drum.

Now the ( words are failing me ) bit that plugs into the transfer case thru the seal that drives the rear propshaft.!!?? , that chrome bit had a slight
groove worn into it.

Is this a hard bit to get repaired or can you actually replace this part ?

any advice would be appreciated.

Now for a drink

The output flange can be speedi-sleeved ok to cure the groove in the seal running surface. When you re-do it, use some decent silicone on the splines in the middle of the flange and on the splines of the output shaft.

The output flange groove will probably be responsible for the leak, although I would be inclined to check the transfer case breather is not blocked and that the bearings are not loose, allowing the shaft to move.

The flange can be repaired by most engineering shops using a speedi-sleeve, or Four Wheel Drives, for example, do a changeover on them for $45 in the last catalogue I have to hand. New ones are probably available as well.

Thanks heaps guys.


If it is not raining this weekend it will be coming off for a check.

Another has told me to check the felt seal castelated nut for tightness.

But I am not so sure .

What esactly is a Speedy Sleeve?

Does that mean they lathe down the shaft and press a new pipe over it.

A Speedi-Sleeve is a thin stainless steel sleeve that fits over the worn shaft. You can do it yourself as the sleeve comes with an installation tool and instructions. The groove in your flange might need to be filled with an epoxy filler first, depending on its depth.

Take the worn part into the supplier so that they can measure it and supply the correct one; you will also need some shaft sealant such as Loctite to seal under the sleeve,

Something else to consider, is to make sure the breather isn't blocked. The breather for the t-case is actually in the gearbox top cover - a metal plate with a hole in it. Make sure it isn't blocked, as it will not help your seals keep the oil in if it is.

EDIT - I just saw JD beat me to it...

Others may disagree, but I always use a small amount of silastic/RTV on the felt seals.

thanks for all the advice guys.

Been a bit busy , but i have got a nice second hand flange with a smooth ungrooved surface to fit into the Transfer case tomorrow.

got a bit of a journey planned so this will be a good test.

got some new felt seals , and have checkedthe breather is definately not blocked

thanks again.
