Winston,
Searching the web I came across the double hammer technique that you described, but I didn't try it out. I will next time. I would like to see it done. Unfortunately I read your message today and the ball joint finially yielded late last night.

I would like to say that this joint was really stuck!!!

After taking off the brake rotor and caliper and repeated pounding with the pickle fork (I have 4 different ones to choose from). I then decided that it was time for the torch.

I heated up the ball joint shaft, melted what remained of the boot and singed the dust cover for the ABS wheel sensor.

To no avail it still wouldn't come free. So I removed the tie rod end (with the pickle fork). It came off relatively easily. Then I removed the three bolts that hold the bottom plate to the spindle.

Next I removed the inner bolt on the other control arm. And I took everything off the car.

Working on the concrete floor I applied a two jaw puller to the evil joint. This proved fruitless.

So I grabbed the torch and began heating the joint from the top with the puller still pressing on the bottom.

As soon as the joint got hot the puller snapped off so I turned off the torch, picked up the assembly and hit the bracket four times with a hammer, the bottom end of the ball joint was in contact with the concrete floor.

In the process of hitting the bracket the other ball joint came loose and just fell away (not the thrust arm the other one). And I never event touched it, well I did remove the nut but that was it.

So after four blows the dreaded thrust arm ball joint came free.

I think somehow it knew that I was about to give up and order a new plate. 8)

Thanks
Paul
