[Vwdiesel] Ball Joint Conquered

Gang,
Last week, I posted a plea for help on a ball joint. Ideas flowed, and
today I got a chance to go after the balljoint. By way of explaination,
I'm doing the strut cartridges, and the brakes, before I tackle a
block problem.
-sway bar didn't appear to be problem with control arm movement. Actually,
the swaybar bushing might be a little worn. Disconnected it. No luck.
-PB Blaster, Liquid Wrench, and other penetrants have been applied for
the last week. Put some more on. Hammered.
-beat on the knuckle clamp gap with a cold chisel, using it as a wedge to
open things up.
-With shields up, I applied heat to the balljoint and knuckle clamp fitting.
Stuck the torch tip right into the knuckle clamp and heated. Several times, no
lock.
-used more penetrating potions. Remember, the joint has soaked in penetrant
for one week.
-tried lifting the car up, by a tire iron, using leverage to pull the
knuckle clamp off the ball joint. Allot of messing around, some hammering.
No luck.
-torched things again. Did more prying. No luck.
-stuck cold chisel on air hammer into knuckle clamp. Buzzed for a while,
then tried prying things apart. No luck.
-more penetrant. Ate lunch.
-stuck tire iron into steering knuckle clamp. Tried prying to open things
up more. No luck.
-got "drag link" socket, mounted into 18" breaker bar. Wedged into clamp
and applied force (FWIW, I'm 76" tall and weight about 265#). Drag link
socket got munged (well, really bent to pieces). Put jack tension on
the old tire iron again, and beat with a 3# hammer. Knuckle starts
slowly sliding off the ball joint. Since it's moving, I decided to not
apply harder hits. I really don't want to hurt the ball joint.
A hundred or two hits later, the knuckle is off.
So, the people who suggested wedging a screwdriver or some wedge into the
clamp on the knuckle, were the ones who appear to have won the prize!
Except a simple wedge, like a cold chisel, was inadequate. I haven't
used the drag link sockets often, but when I do, I usually damage them.
This was the case today.
So, I got everything far enough apart, so that I could replace the
strut cartridge. Needed the torch several more times. Most notable,
I found that the strut cartridge had collapsed internally, and the
walls of the cartridge looked like they had been pinched in a giant
pliers. Later, I tested the strut for range of motion, and found it
to be generally good through its whole travel. Perplexing.
Thanks again to all who mailed in their helpful hints.
