pinion nut removal

Ok, this may be a stupid question, but here goes. I have a dana 44 out from from under the vehicle and sitting on jack stands, no wheels on it that I need to replace the pinion seal. So, this may be the dumb part, how do I get the pinion nut off. Everytime I try to torque on it, the rear drum just spins. Do I have to have wheels/brakes on, does it need to be installed in the vehicle, or is there some trick. I thought this was a no brainer but I am stupified and stumped [img]/ubbthreads/images/graemlins/confused.gif[/img].


Thanks for you kind remarks and help

Re: pinion nut removal

Ever hear the phrase "you learn by your mistakes"....so how do you think we all got so bloody smart.....

Not a dumb question....if you had FSM you would see where it references a special tool for just holding the yoke.

I made one out of a piece of 1/4" bar stock that was about 3' long. If I ever make another one I'll make it about 6' long. Unless you have a breaker bar that is at least 2' long...don't try it....or you might try an impact wrench....it takes some serious torque to get that baby loose.....you ought to see what it takes to get the pinion gear our of an AMC20.....anyone who has done it knows what BFH really means...

Re: pinion nut removal

Impact will usually zip it right off, at least mine will.

Re: pinion nut removal

You might be able to use a pipe wrench to hold the yolk. You'll probably need a extension on it though and someone to hold it while you break the pinion nut.

Re: pinion nut removal

Pipe wrench works great, no extension needed. Just get the jaws to grip the yoke and spin the nut off with an impact. It'll take about 30 seconds to set everything up. If you don't have air tools, then have someone hold the pipe wrench while you turn the nut off with a breaker bar.

Re: pinion nut removal


If you can 'ZIP It Off' with out a breaker bar holding the pinion yoke, yours isn't torqued and rusted on properly. [img]/ubbthreads/images/graemlins/AR15firing.gif[/img]

Mine took a liberal application of high explosives and one stout impact wrench.

Use a puller on the yoke, if you hammer it off, you run the risk of damaging the pinion bearing and/or the pinion/ring gear.

When it comes to installing the pinion nut, you will have even more fun!

Just take a flat piece of plate steel, cut a hole big enough for your pinion nut socket to fit through, then drill the four smaller holes for the yoke strap bolts.

Then weld on a really LONG handle... Someone is going to have to hold on to that thing while you torque that yoke nut back on...

Remember, you can't hammer on the yoke to get it started or you will force the pinion into the ring gear... BAD IDEA!
You will just have to clean off and out the splines well enough the darn thing fits on there far enough to get the nut started...

This is just all kinds of fun if you aren't set up with a 3/4" drive set...

And if you don't have a puller, I came up with a trick when I didn't have one. I put the u-joint u-bolts back in with a wrench under them across the pinion. By tightening the u-bolts, it pressed the yoke off.

Re: pinion nut removal

Thanks for all the great ideas, I had no idea, obviously, that this would be such a big deal. What is the torque (lbs) needed for the nut when putting it back on?

Thanks again.....Rob
