So yours is looking like just the oil churned up to an oil ‘milkshake’ whereas mine clearly has CV grease in it? That being the case, yours is nothing like mine in actual fact.
The thing is, although polished, my shafts weren’t exactly grooved.
Yes Chris. A tight seal does not mean an oil tight seal.
I had my 80 at 3 years old with 35k on the clock and drained the oils straight away. I was mystified by the milky appearance of the oil. It now appears it's "normal".
I know some might not agree but I think as it is a one way seal grease must be getting past the seal by pressure build up by heated up swivel hubs after braking.
I MUST get round to putting the airline and gauge on mine and see if it bubbles round the external seal.
Reading posts I think the commonest problem is diff wear. Certainly heard of horror stories. However if the oil is changed as per owners handbook (memory 36K) you'd have to have a serious grease leak to ruin the diff.
This is what I don’t get. Not arguing at all but I’ve encountered other gearboxes full of grease and I’ve encountered them full of oil and both media are lubricants so I don’t understand why there should be wear in a diff that has a percentage of grease mixed well in with the correct oil. I’d really be interested to know.
