I need to replace the pinion on my Dana 30. If it uses a crush sleeve, I'll probably let Baertrax do it, if not, I can do it myself?

Does anyone know if the '87 uses a crush sleeve?

This is why I need to replace the pinion...

I don't know what year they switched, I was wondering the same thing.

I am not sure if it is shimmed or not. But you are referring to replacing the "yoke." You should be able to do this because the pinion is either shimmed or uses a crush sleeve. If it is shimmed it doesn't matter because you just torque it down to specs. If it uses a crush sleeve just torque it down to spec. It takes a lot of force to crush the sleeve. I believe it is around 400 ft/lbs. to crush it. If you are replacing the yoke with an impact wrench stop when starts to bog down. You will be able to tell.

Unless there is other damage we cant see the pinion should be fine. All the dana 30's I have worked on do not use a crush sleeve so it should be an easy yoke swap.

TJ Dana 30s use crush sleeves, but I think YJ and CJ Dana 30s used shims so you can remove yoke and replace it and not mess up the diff.

Replace the strap style yoke with a U-bolt style yoke.

hey...just remove the carrier and drop the pinion to find out...I don't think they use one but if it does don't worry about it if you are ONLY replacing the pinion w/ another of the same type. just throw a new one back in there w/ all the same stuff that was on the one that broke....then check pattern. If it's not good then sh!t...fix it....it should be good though it the previous one was just defective or pushed too hard.

Okay, well not every having taken one of these apart, I don't really understand how the yoke comes off. So the yoke (the part missing the little tab to hold the ujoint in place) will come out without messing with the crush sleeve?

Also, can you replace the straps with u-bolts on a dana 30? I was told there wasn't room for the nuts???

I read this:

"Dana 30 Front Axle (YJ)
There is insufficient room behind the stock yoke for the U-bolt nut on the YJ front Dana 30 pinion yoke. The entire yoke must be replaced with Spicer yoke #2-4-8091X and U-bolt kit #2-94-28X to upgrade to a U-bolt connection. "

I don't believe Dana 30s went to the crush sleeve until 97. Could be wrong.

To remove the yoke, remove your driveshaft, there should be a big nut holding the yoke onto the pinion, romove that with impact gun, use a puller (if necessary) to remove yoke from pinion splines and replace with new/used yoke and retorque to factory specs. You shouldn't have to mess with shims or anything.

Just spin the nut off and tap the yoke off. If you want a U-bolt yoke..any 1310 dana 44 yoke will slip right into place. The spicer numbers you have look right but the junkyard is cheaper. The u-bolts are only a few bucks but the yoke is expensive new.
