unrelated, english american = gray. english english = grey

thanks for that much appreciated
after some further research I thought it might be that ?..I'm going to check the grease levels in the ball joints

this is a photo ( not a real good one )of the front diff oil ?I could be described a a little grey or milky

if it was milky what is the significance of that ?IMG_0123.jpgIMG_0123.jpgIMG_0124.jpg

I did put a strong magnet in the drained oil and no particles were observed

Yes that definitely possible too ????..what would I do to remedy this ??check the breather on the diff ?.not sure where to find it ?has been suggested to rechange that diffs oil again in 5000 kms ??but if it's water getting in where would I look to fix the problem

The breather is in the top of the housing on the passenger (long) side of the diff.
It should have a hose on it that heads up into the engine bay, make sure this is higher than the deepest water you play in, the rear breather is often lower than the front one.

Check the hose is not blocked or broken, the fitting in the axle housing can get blocked as well, it can be unscrewed to clean it out, there is a washer on each side of the banjo fitting, don't lose them.

The attached pic is a Disco, but my 95 Defender is the same.

Thanks for that ?..I'll have a good look a check out won't hurt.

after further research on google looks like my oil colour ( gray/greenish ) and is as pointed out above due to the migration of the ball joint grease

I found a video of what milky diff oil looks like and it was pretty white not what I had

Now going to check the grease in my ball joints.

I'm a stumbling learner in Land Rover maintenance??..so appreciate the patience and help

so far have saved a fortune on service costs?.love it
