Hard to say. If it came out easily, then I would replace the shaft, but if it's a tight fit you could try pressing it back in.

this is a new driveshaft. I just installed it about 2 weeks ago when the other one snapped on the other end. it came out of a durango bag.

I see that permatex that makes what they call retaining compound. it's specifically for holding stuff like that in a press fitting.
if I can find it I might use that over red loctite.

still getting the mugen tool anyway. I have lots of worn pins to replace soon. all of my cars need some.

I close the hole in a vise a little after the pin is removed. Then re-insert the new pin and make sure it goes in hard (that's what she said, I know). I use a Mugen pin tool...

I had some Agama shafts that were terrible and didn't like new pin replacements; they would always backout. I used a drop of Loctite 620 Retaining Compound when pressing them in, fixed it.

Loctite 609 or Loctite 640 should do the trick for shaft pins. Never hurts to have a bottle laying around, works great on lots of other stuff.

How do you do that without ovaling the hole? You can only press 2 sides

The hole was probably oval when it was originally pushed in to get that interference fit...

well I work in a machine shop and usually holes are undersized for press fittings.
meaning they make the hole a few thousandths smaller than the pin.


anyway my mugen press tool came today. I was able to push the pin back in with ease. probably too easy. went to napa and they sell the retaining compound but it's $8 and change.

I'll try my red thread lock first

also if you guys are familiar with this tool, I'm having a bit of trouble wondering what exactly the clamping ring is for. the instructions are somewhat vague.

here's a picture of them if someone wants to take a stab explaining why it's needed. to me it seems unnecessary. look at step 2

Clamping ring assures you press the pin to the exact measurement so it is even at both sides. Once you get to the ring the pin should perfect. Not too short or too long.

Set it to a driveshaft that is correct and then you have exact location.
