The wire brush attachment on the dremel was really good for cleaning all the rust off. Will put everything back together this weekend when the weather warms up!

Also a long barrel air hammer is more effective since the hammer has a longer travel thus more force when it hit.

Is that a 1" hammer head? Was considering that but wasn't sure if that was too big for the top of the balljoint. I got a 3/4" tapered punch and it worked pretty well. It was a lot smaller than I thought it would be, so the 1" will definitely work too and is probably a better choice for the reasons you mentioned.

That is correct. Although I did remove the half shaft from the hub as I am replacing my CV joint at the same time.

I think this is about right
Its a painful job without an air chisel, as I said, I am good with a grinder and did mine with out damaging the knuckle, but you need time and patients. After you weaken the ball joint housing, then the BFH comes into play. Smash it, bang it, and go to town on it.... it will come out... but it makes you work for the victory.
Good luck. |
Thanks, I got the drivers side out a few days ago with the air hammer and will do the passenger side this weekend. Stay tuned for a video with the air hammer in action!

Both ball joint soaked with penetrating oil for over 24 hours. The whole job took over 4 hours. I spent half the time to complete same work on my 03 3.0 with 200K miles. On both cars these parts never replaced in the past.

Wow! I'm surprised you can't get it out with the air hammer from the start. Took me around 5 seconds, although mine was a super-duty Ingersoll Rand air hammer. What punch/hammer did you use on the air hammer? Also my drive axle was removed from the hub so I had more room to work with.
