Oil leek from diff English axle
Looking at the car this morning there was an patch of oil under the diff. Had a quick look about but could not see any thing obvious. So what are the
normal suspects?

Front seal is my guess.
It looks like the Midget is winning at the moment......

I had a simular experience, oil .... no obvious leak! First smell the oil (weird I know) and check it is diff oil not something else. If it is I would
check the front flange of the diff is not coming loose. (Nut holding is usually within the space left by the UV of the prop. Mine had come loose and
oil was weaping out of there, being removed by the prop spinning at speed and so I couldn't see where the leak was until I took off the prop and
checked the nut on the front flange of the diff.
Only a thought!!!

There have been quite a few instances of oil leaking through the factory weld where the diff mounting face is welded to the axle casing - my axle
being one of them....
It's usually only a very slow leak, just enough to leave that annoying patch on the garage floor. Hopefully not the cause of your problem, but
worth looking out for...

It could also be the preload tube between the pinion and the drive flange. With abuse I believe these can crush further and slacken off also causing a
leak through the front seal.
For competition use etc many people fit a solid tube instead of the crushable one to get round this. Worked well for us anyway!

I have this fitted too - had a leak fromt hat front seal caused by the continued crushing of the origianl crush tube. I had my axle refurbed by
Procomp, who fitted a LSD and replaced the bearings/seals throughout... problem solved.
dont be tempted just to tighten up the nut on the front of the axle - if it is loose, you need to set it up again properly!

Mine had a leak for sometime that l lgnored as i thought it was the front seal leaking.
When i got around to looking at it it tuned out to be as simple as retightening the diff to axle mounting bolts.

I thought one of my brakes was leaking because there was some fluid on the inside of the wheel and running down onto the ground. I replaced the brake
cylinders but still found fresh fluid on the wheels. I decided it was probably oil so I looked into it and there's a fairly common problem with
the seals on the end of the axle where the hub attaches. I can't remember the specifics. Someone suggested removing the seal and putting some
silicone sealer on then replacing the seal. You can probably find it with a search.
I never got around to doing it myself.
