Rear axle seals

[Maurice Donckers]

yep that is the one I mean , this is again mounted to keep the grease inside .Is this now the corect way?

Hi Maurice, it sits as it was, when i pulled it apart.
There is another type of seal, which is steel and cast iron, or steel and steel.
It would be nice if you could post a picture of the new seal.

Hi Maurice,
The seal Lynn showed is as on the Ford axle used in a Carrier and there are no inboard seals on the halfshafts, so this seal on the hub nut lockplate is to stop the oil getting in to the grease and diluting it. The British Fords had a mechanical seal, as Lynn described, a sprung steel ring around the plate.

I have no new seal , these seals come out of several of my CMP axles , some facing inwards , and some facing outwards, but I can`t find wich way round they should go , the seal in the picture is facing inwards to keep the grease in , and not to stop the oil going to the bearing

Maurice, unless you're going to park on steep sidings, I don't think your ever going to have a problem with them mixing. The level in the diff is lower than the axle tubes, and your probably packing your wheel bearings with high melting point grease that isn't going anywhere away from the bearings. The seals in reasonable condition will be enough of a physical barrier, which ever way you fit them. I myself, would however fit them to keep the oil out of the bearings.
You've probably already decided that anyhow.

Hi Maurice and Lynn

The picture of the seal looks like those used on 3-ton Chevy CMPs as well and I have never found a modern replacement. So if anyone does find a modern equivalent please make a general posting on the source.

Does anyone have the Carrier part number for this seal so we can see if it is the same as used on Ford and Chevy CMPS?

There was a lengthy thread on these type seals (outward sealing) concerning trucks some time back that I will try and find.

These seals on the trucks are really not critical as you really need to get the truck on quite a side angle for the differential lube to run out this far in the housing, but on a carrier it maybe much more critical.

Cheers Phil

Yes phil , the seals on chev, 15cwt 4x4 upwards , and Ford , and Carriers use the same seal.

Are these seals steel encapsulated?
Do they have a steel outer rim then a rubber lip?
Is there a spring inside the rubber lip as for a rotary shaft seal?
I know a company over here that may be able to either make them or source them.
Can I have full dimentions and rubber hardness please and will enquire, they are only local to me!

Maurice,

As discussed earlier, I don't recognise the seal as I don't think my truck has it.

Can someone point out the part number, please? See attached exploded view.

Thanks,
Hanno
