9 in. Pinion Yoke seal leak repair help
I have a pinion yoke seal leak. It isn't bad but I want to stop it. I will replace the seal but do you ever replace the yoke if it isn't broken? Does the surface of the yoke wear in the seal area to the point it will leak even with a new seal? I'm asking because a tab was broken off the yoke (that keeps the u-joint caps centered and in place) of the limited slip pumpkin I bought so I put a yoke in from another older rear end I had. I don't know, that thing might have had a million miles on it. In any case, I never did think the seal was snug enough so sure thing, it leaks a little. I'll buy the yoke if you guys think they wear out but won't spend the money if they don't.
Also, during the course of this I will lose most of the rear end oil. Do I need to put in another bottle of friction modifier when I add new oil? I'm doing this in the car so it won't lose all the oil.
I won't even get into the crush washer, pre load deal. I don't even know if it has a solid washer or crush washer. Crush I assume.
Any suggestions or help will be appreciated. I've never worked on rear ends to any extent at all. I drive my car about 2,000 miles a year and don't race it. This thing has been leaking a little for 3 or 4 years.
