Re: Rear End Leaking !?!?!?!

You mean the differential cover? You can pop that bad boy off, get a new gasket from a parts store. A little RTV and your good to go.

What exactly do you mean by "tail".

If it is leaking from the back then it is the cover, or fill plug.

If it is leaking from the front it is the pinion yoke seal.

If it is coming from the sides it is one of the axle shaft seals.

There is a seal on the input yoke and one on the diff cover.

check the pinion seal

Ummmmm at the risk of being a jerk.....crawl under it and look? Hint...if it has one of those stupid rubber fill plugs, they are prone to leaking...other than that....pinion seal...

Blindfolded, 5 bux says that it's the pinion seal.

Alright, those sagging rear springs that I was going to replace this past weekend finally screwed me. Instead of the universal breaking it broke about 1/4 to 1/3 of the yoke off of my 8.25. All the way down the splines. the broken yoke then tore the oil seal.
So my question... I have no problem with putting a new yoke and seal on, but I am not sure about the crush sleeve. How much torque can I put on the nut when tightening everything down without crushing it more? I am missing those couple pages in the service manual that pertains to this.
Also, Is there a u-bolt style yoke fro this axle?

Can they be replaced with a steel bolt? Mine leaks down the back cover too.

Torque the yoke down until you feel a slight resistance turning the yoke. It will take alot of torque to get it there. Plan on using a big breaker bar. Turn the nut about 1/8 turn at a time and check the turning resistance of the yoke. You want just a little resistance on the yoke. About 18-24 inch pounds if you have a dial indicating torque wrench. Noone makes a u-bolt style yoke for this axle that I have found yet. I modified a yoke by drilling out the bolt holes for some u-bolts I got from Napa. I don't remember the application but I think it was a mid 90's dodge dakota. I then milled the back side to make room for the nuts and washers. Any good machine shop should be able to do this for you for around $40 or so.

Thanks
