Leaking seals 53 M38A1

[Casey B]

Have seal issues on rear diff and rear output shaft of transfer case. I am not too worried about the rear diff drip...and the proceedure looks pretty simple.

The rear output shaft of the transfer case is soaking the park brake assembly.

I took the park brake assembly apart after refilling my now empty transfer case. (I wondered why the oil stopped dripping...it was empty!) With the drive shaft off it didn't leak. Once back on you guessed it. So have to change the rear seal.

Is it close to the same proceedure to change this seal as it is to change a diff seal?

The diff seal although I have done it seems pretty easy.

Do you have to remove the speedo cable before removing the seal?
With the drum for the park brake installed same as rear end remove nut with impact gun line it up with marks made before removal?

Anyone know the torques of the rear diff nut and the rear output shaft?

I have heard you can just mark it and tighten the nut to the mark?

Any help will be great!
