Right, 6 hours later, it is done.
This is how I did it, not the official way no doubt.
Firstly, turn the freezer to max cold and put your new ball joint in there overnight.Cold contracts.
Remove the front hub and driveshaft as one,then the whole knuckle.
Getting the lower taper to pop out was extra griefy, I cut the threaded end down a bit and used a normal separator.
Getting the old joint out took ages.
Hammering gets it moving about 1/4" only.
The way round this was to cut the bottom half off, remove the ball,and drill a hole through the upper centre of the old joint.
Using a small cutting disc, cut a few lines across the top, like a star,then hacksaw through the remains of the joint.
This removes the tension off the joint in the casing, and it can be walloped out.
Clean up the casing, warm up using a blowlamp, and the quickly line up the new joint.
I pressed it in using a sleeve and a bottle jack, the weight of the car being supported on it.
Careful hitting of the axle casing allowed the
joint to sit home.
And that's it. a real pig, but nicer steering at the end of it.
Enjoy yourselves!
Jim.
