Sometimes these can be a real PITA. Smetmes they come out with just a few little taps. I had to cut the ends off one once. I think the vibration from my Sawz-All broke the rust. Otherwise, keep pounding. Heating/cooling might help break the corrosion.

Cheers

Try a gear puller under the LCA to the end of the shaft.

When you put them back together use anti seize grease on the shaft. Then rotate the shaft by the head.

One I had like that, and I eventually found it was the inner sleeves of the Metastic bushes frozen to the shaft.

Did as Doug, cut down between the cradle and the arm, and the section 0f shaft inside the cradle tube simply fell out when the rest was removed.

Another had that shaft solid in the cradle tube, both side, NAH, another cradle was easier and cheaper.

Those lower pins are not expensive, and YES, lots of Anti-Seize on assembly.

The left side came out with a tiny tap. And all new and replaced bushes.
I lubed that thing up.



@grant. Im alittle confused about your Explanation,
i cant seem to visualize it.
And by cradle are you talking about the whole middle of the sub-frame?

I dont see how i can cut anything, everything is so tight.

OK,

Probably not visual due to rubber swelling.

A saw bade of some sort is easily working into the gap between the rear face of the wishbone, and the cradle/subframe/whatever its called up there. NOT as simple as look and cut, a bit of blind faith, as you know that the shaft/pin, is down there somewhere. All I had at the time was a hand hacksaw and a packet of blades. These new fangled electric saws will do that in a few minutes.

Cut through both sides of the cradle, as in front and rear, so the arm will fall off, then the pin inside the cradle can be addressed, and the remains inside the eyes of the arm can be bashed out.

FIRSTLY

Establish that the seizure is either the steel sleeves rusted to the pins. These sleeves form the INNER section of the Metalastic bushes, OR the pins/shafts are rusted to the steel tube that passes through the cradle.

If the latter, oh boy, that is where I went with another cradle.

The former is the method that works with the cutting of the pins, and fitting new pins.

Remove the nut and washer. Heat the bushes up with a MAP gas torch. The bushes will turn to goo and you can bang the rod right throug the melted bushes.

I am with Grant. I had exactly this problem both sides. An electric hacksaw between the wishbone and the cradle did it. But then it is likely the sawn off pin is still corroded into the tube through the cradle, so it will need to be drifted out with a steel drift and a lump hammer.
I had to do both sides of the wishbone, thenm I had to burn out the bushes from the wishbone eyes to get them free. As Grant said, the steel inner corrodes onto the pin and just burning the rubber with the wishbone still in place may not work. New pins are cheap, but I advise welding in place the thin fixed "nut" at the rear end of the pin - which is otherwise a press fit onto the pin, they can come loose.

Well i got it out heating then melting worked great. It wasnít stuck in the shaft of the frame itís self the bushing rusted itself to the Rod. I got some of it out and then cut just enough to be able to pound it out the other way. But its free!! Thanks for the suggestions everybody

And to add to frustration I ordered a fulcrum Shaft, with a set of lower bushings from xks’s I was a little bit put off because they are the uro brand, I called and asked them if they still had OEM and they told me they sold a few hundred with no problems.... so I thought I’d give it a try and well I ruined my new fulcrum shaft along with the bushings because the fulcrum shaft no matter how much I try I even froze the rod could not get it through.
