    Just over night while on jack stands, my damn front pinion seal is leaking now. Does anyone know if its a pretty simple job to replace?

    yes it is easy to replace it..all you need to do is pull off the yoke and pop the seal out and then tap the new one back in...make sure to put some lube on the new seal before you put the yoke back on....

    I did mine three weeks ago and no probs. When you disassemble the yoke, mark the relationships between the pinion shaft, pinion nut, and yoke with paint or your mark of choise. When you put it together, just line up the marks. If you go too tight, the crush sleeve on the pinion shaft can get squashed. Happy blazing!!

    All the directions above are good. Like Skyblazer said mark the nut because I believe 10 bolts do have a crush sleeve...

    You'll talking about like counting the number of threads to tell how deep turn the nut as well as an alignment mark?

    I was just referring ot how far the nut went on. If you tighten it up too much the nut will crush the crush sleeve farther and your pinion depth will be off.

    The last sentence is incorrect, you can crush the sleeve, all you want, and the pinion depth will not change at all.
    The crush sleeve is used to set pinion bearing pre-load.
    Please learn your terms !

    But if the crush seelve that has been crushed on a rear is re-used, then you may need to used some shims between the the crush sleeve and the bearing. Yes the crush sleeve does push against the bearing and hence adjusts the pre-load, but if you reuse the crushed sleeve, like I said, you may need o use some shims to allow for the proper pinion depth. I just cheked with Randy's Ring and Pinion and this is what they said.

    So in essence I was partially wrong and partially right, I should have explained myself better in the first post. I apologize!

    ha, No way something is still wrong in your explanation.
    Even if you install without the crush cleeve it will not change the pinion depth.
    Randy's is not the Authority for pinion depth, I am.

    Hey Executioner,

    All I've seen is snarky remarks from you. If you are the expert lets hear something constructive.
