Rear axle seals

[Maurice Donckers]

Does anybody know how the outher seals ,the ones near the half shaft should be mounted ?
I took several axles apart , on carriers and CMP`s , but on one the lip faces inward to keep the bearing grease there , on others it faces outward . There is no clear answer in the manuals that I have got .

Hi Maurice,
In theory the seal should stop the oil getting through to the grease, so lip towards the oil.

[Maurice Donckers]

but there should be no oil there , because there are seals next to the diff.

Ah, forgot about that............ I was thinking of another axle (not Carrier).

Those inner ones often get damaged when removing /inserting half shafts, wonder if it is what we call a "belt and braces" method, if one leaks there is another one!

How about some pictures Maurice? Which type of seal do you mean

[Maurice Donckers]

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

"5. Install the grease seal with the lip on the seal pointing out, . . ."

Lynn my C15 no11 cab has GM brakes (always poor )they are all round the same as GMC cckw banj front shoes . Brake cilinders are also 1 1/4 front like banjo , but the rear ones are outward the same as 1 1/4 but are internally 1 3/8.
My CGT and C15A have ford products .

Michael , thanks , that must be it then , wonder how manny are mounted the other way round , that also makes clear why there are 2 treaded holes in them to pull them out , if the lip is facing inward , then resistancewhen pulling them out would be less.

Hello all.
A product that you can pour into the diff that will lube and stop the seal from leaking Ive only come across this one www.liquidintelligence.com.au has any used these products before? Cheers Lads

[Maurice Donckers]

Shane to my knowledge these products only work on modern rubber seals , not on our old leather seals . it makes the seal to swell a little bit , but in my opinion if a seal is worn , the only way to repair is to replace the seal.
