Mine is dripping oil, so assuming it's the gasket thats failed, is it possible to replace the gasket on one of these with the rear axle in situ?

And does anything else need to be removed to get the cover plate off - handbrake rods, brake pipes, etc?

I don't remember having any trouble doing it, it was quite straightforward. I certainly did it with the axle in situ on mine.

It should be possible to change the gasket in situ.

Before you change it though, just check the drain/fill plugs and if possible treat them to a bit of PTFE tape or other thread sealant.

The other thing to check is the pinion shaft seal, if they leak they do tend to track oil back. If it needs replacing, it can be done in situ, but don't expect it to come out in one piece. There are three versions so make sure you get the right one!

Kind regards

I'd second this. Mine was dripping so I bought a couple of gaskets, turned out the leak was from the fill plug. PTFE tape seems to have cured it. I now have a couple of gaskets I don't need!

Thanks for the tips. A closer inspection is needed before any work is started!

First I would check that it is actually the gasket.

If the vents are blocked , the axle casing can be pressurised , and the oil will travel along the underside and drip off the lowest point (the diff casing) making it look like the gasket has gone.

They are normally found on the axle tubes next to the brake back plates at the rear of the tube about halfway down. They face rearwards to avoid collecting road grime, but can still suffer from it in that location.

If as Andy suggests, the diff vent hole is blocked (and it's a tiny 1/8" hole), it would be a good idea to pop the rear drums off and check the oil hasn't worked its way past the oil seals onto the brake shoes!

Thanks for the heads up on the vent holes, I'll certainly check them.
