8 and 3/4 swap

[old guys rule]

Swapping out the center section of my 8 and 3/4. Can pull the axles out only about 4 in is that far enough? However I would like to change the foam gaskets. What am I missing?

What year? If they are non taper it makes no sense. 4 inches out there should be nothing left to keep them from coming out. Got pictures?

Sorry, rear end is from a 69 roadrunner. 742 center. I'll get some pictures tomorrow. It has to be something stupid I am overlooking.

That should do it.

I haven't tried to pull the center out yet, it probably will come out no problem, not tapered axles. I figure I should change the phone axle gasket s well I have them out so I need to pull the axles all the way out, correct? Haven't done this since high school about 80 years ago.

May I ask, what are you swapping from ? to ?

The FSM recommends changing the inner seals every time an axle shaft is removed. They're not expensive and you're already there.

Pull on the axles a bit harder, they will come right out.

He claims they are already out 4 inches which does not make sense. At 4 inches the splines are out of the spiders and the bearings have to be out of the tubes. There should be nothing else holding them in.

Is there a difference between the tapered and non-tapered foam gaskets, seals, and/or the process in general?

From 4:10 to 3:23s for the highway

Can't blame you. On the car I last restored, the only thing I didn't do, was the 3.91... now I'm too lazy to swap the pumpkin.

I don't like resting the axles on the seals and pulled them all the way out and was very careful not to drag them on the seals. I used to change gear ratios quite often and wasn't going to change the seals on every swap I did unless they were already seeping. Oddly enough, never had a problem messing one up doing it like that.

Found an old manual. The emergency brake strut needed to come out. Didn't see that. Good to go now. Thanks, Dave

I just lifted the strut a little bit with a medium sized screwdriver and the axle would slide right out. It would rub on it but not enough to hamper it.
