    The front pinion yoke on my 87 is broke and I'm getting ready to fix it. Questions are what special tools might I need, do I need to replace the pinion seal? Again I'm only replacing the yoke. Any other suggestions tips or tricks welcome.
    Thanks a lot.

    Yeah, and rule of thumb is, if any seal has been unseated, replace it. Wear over time sets the seal to remain sealing, replacing a part, or even removing a part from a seal can and more often than not, damages that sealing ability and they tend to leak. If a slight wear groove has formed in the part being removed, once it is pulled from the seal the flex can cause micro cracks and will leak, so yeah, not much money to replace it once, vice having to take it apart afterwards to replace it a second time.

    very seldom do they break.if the yoke is broken it would have taken a lot of force to do that.depending on what diff you have you may have a crush sleeve that would need to be replaced.a lot harder to change a yoke in a diff that has a crush sleeve.you can't over torque the nut,
