Yoke seal leaking on my 57 super 88, have any of you replaced the seal ? If so was it hard to get the yoke to brake lose, if so how did you remove ? What size is the nut holding the yoke on the shaft? , I have to replace the seal .Any information will be helpful.

Thanks -----------SID

Sid, I don't have experience on that vintage others will; but, which yoke? Trans/front or diff/rear?

Good luck!!!

1 1/4" nut / socket
Drain the rear of oil
if it has been on for a long time you might want to pay to get it done.
Some how you will need to tap the yoke off the pinion snout splines.
pry the seal off DO NOT gouge the casting where the seal meets the casting or you will have leakage from there.
You will need a big diameter sleeve metal ring giant socket to drive the seal in square
try to keep the area from oil...(hard to do in the car)
coat the seal outer diameter with RTV sealant
drive it flush with the casting (keep it square)
lube the seal lip with oil
install yoke
tighten nut as much as you can with your hand wrench and lock tight.
after you think you got it on with NO in/out or up down play, only spinning
(you really should not be able to crush the sleeve with your hand tools your just not stong enough...IF by chance you do somehow over tighten with your hand you are in trouble)
You will have to redo a crush sleeve.
(this is all very doubtful)
Stake the nut into the thread with a point steel punch so it does not back out.)
You should be good.

THIS IS NOT THE TEXT book version.
The correct way is always to replace the crush sleeve. BUT I doubt you want to go there.... Entire rear tear down.

We do these seals on 8.5 12 bolt etc all the time and never have issues this way and is much more cost effective for the customer.
