    Oil leaking Jag' rear...

    Hi there from Norway!

    The Jaguar rear axle on my '34 leaks oil in the front (where the drive shaft is attached)
    I have bought a new seal, a the circle formed one with rubber on the inner part vulcanized to the metal outer part.

    Is it easy to change this seal? Just loosen the big nut in the centre of the yoke, pull out the yoke, replace the seal and put it all back together again?

    i used to work on jags for a living but kinda scratching my head to remember the process, dont think your to far off, but do seem to remember the importance of a new nut to secure the yoke and for some reason a collapsable washer?? but it was a long time ago!!
    i want cubic inches! lots of em!!

    Thank you for your answer!
    I asked the same q over at the UK Cobra forum, too.

    I was told to not overtighten the nut, otherwise the collapsible washer had to be changed as well, and changing that involved even more work.
    Nothing about changing the nut itself tow...

    The collapsable washer set sthe pinion preload so if you just keep tightening you will change the preload .What I do is gradually ease up the settings on a torque wrench until I can see at what torque it comes undone .Change the seal and then refit the nut, with Loctitie ,adding another 5 lbs to the torque figure. Works MOST times

    I now remember that I had the diff (no axles or stuff) standing on the "nose" over night when I had painted it. No rough handling or something. Just carefully placing the diff on the nose

    Could this cause the collapsible washer to collapse even more? And because of this starts the leak?
    Or would the rubber sealing still had stopped such a leak if it was ok?
