When I pulled the axles the roll pins stayed in the stub axles. they are blind holes so I can't push them out from the back and grabbing them with vice grips and prying has not budged them.

I am sure this has happened to others, What did you do?

I guess drilling them would be an option, but wondered if there was another way.

I used a drill chuck. needs to be one with a key though. Just put the pin in the chuck and turn the key to tighten. it should compress the roll pin enough to remove it. Installation is the reverse...

Ditto on the drill chuck, can also use this method to remove dowel pins sometimes.

Can you just leave them for when you’re reassembling the axles?

His look to be in pretty good condition. If a cv has ever come loose, it is a good idea to make a cleanup cut in a lathe. When a CV comes loose, this surface will no longer be perfectly flat. You will find the surface near the holes to be a tad high. If this is the case, the CV will not stay tight!

If you need to remove them, squeeze with vice grips, try not to deform them for reuse, tap against the vice grips to pull out the roll pins.

Squeeze them in a vice and pull up. Quick and easy.

I am installing new factory axle sets and they already have the roll pins installed.

( cuddyk did a nice unboxing video of these )

Have tried clamping vice grips and using a small pry bar. will try tapping on the vice grips with a hammer. Also the drill chuck thing might be a good idea. I could use the drill press to pull them out.

Drill chuck method did not work for me, Applied some heat and tried clamping with vice grips and tapping with hammer. after no progress I decided to try drilling them.

Major Fail.... these pins are hard.. Even with cutting foam I still had sparks flying , until I had a busted of piece of drill bit inside the hardened spring steel roll pins.

Applied some more heat and went back to the vice grip method. I had measured the height to tell if it was moving, and once I got it to move a little it came out fine.

did the same with the other side, minus the busted drill bit part.

I should have said Lots of heat. Glad it worked.

Can’t tell you how much we use the map gas wrench around the shop.
