Ball Joints removal trick
Hi. replacing the ball joints on my '84 911. No trouble getting the castle nut off and getting the ball joint to release from the control arm. I am, however, perplexed as to how to remove the wedge pin/ bolt. I don't have an air gun (yet), thinking I could pound it from the bolt side to move it out. I loosened the nut to the end and beat on it for a while, effectively smashing the end of the nut down a bit. The wedge pin did not "unwedge" itself.
Am I missing a step, other tricks? PB Blaster? Heat (I wouldn't have thought so, as the bolt would expand...) Your advice is much appreciated.

No help on the pin, but air hammers are amazing. I had to replace a wheel stud on my RAV4, and also thought I could just pound it out. No dice. A five second burst with my air hammer had it out like butter.

Second for an air hammer. They sell for cheap at Harbor Freight.

Thanks, might be the ticket. I also need a bigger torque wrench that musters up to 184 ftlbs...

Harbor Freight would have probably been fine, but when I can I like to buy better. I went with this basic Ingersoll-Rand: Air Hammer
I also have one of their impact wrenches that I really like. Mark

It is a split-beam, meaning you don't have to reset it to zero after every use like the micrometer click-type wrenches. There is a little knob on the side that is rotated to set the torque on the dial. Made in USA too. I have read they make the Snap On split beam torque wrenches. Mark

Hit it harder. They like to get stuck.
Leave the nut on like you already did to prevent it from sailing across the shop. I like a big brass punch for stuff like this as well. It damages the parts less. |

I couldn't get it out on my SC and had to send the car to the Porsche place. They had to take the strut out and use a bench press.
A bit late but I thought I could have fabricated up a jig where I place a small bottle jack in it with the right sized pin to force it out, so strut removal wouldn't be necessary. |

I just did this with mine. One side worked with air hammer. The other side I put in my HF 20 ton press. Came right out with a bang.

I just did mine. They required a little heat. I used a propane torch (so relatively low temp) focused right on the pin. Not even red hot, but a minute or so with heat and a couple taps with a punch and they both came right out.

This is helpful. I can use an induction tool on the bolt side but would have thought getting it red hot would make thing worse. I can try a torch on the pin end.

If you use a hammer and punch use a 4 lb. sledge. Forget the 16 oz ball peen, you'll be at it all day and night.

Air hammer $19 today at Harbor Freight.
If it's roll pin, won't a matching diameter punch with the BFH work just as well? Get a piece of scrap lumber, drill a hole 1/2 inch diameter, one inch deep, and work horizontally on the garage floor. Safety glasses for this one just in case. |

I have always managed to get them out - but with the sort of difficulty you are having. Bit of heat and a sharp crack. But for all these hard jobs, I always reinstall with some never-seize coating. At least some future owner (if not me) hopefully won't have quite the same struggle. And it only costs a few cents to slap a bit on. And who knows - it might be you sometime in the future.

Related question: Once you get the pin out, how do you get out a stuck ball joint stem? I ran into this on one of my ball joints a couple years ago, so I left it alone because the ball joint and boot were still okay. But at some point I will need to get them separated. How do you deal with stuck stems?
