tips or tricks to remove upper ball joints

Mjt 2 April 2005 18:42:07
 x-posted: rec.autos.tech, alt.autos.isuzu - followup set: rec.autos.tech

1990 isuzu trooper (198k miles), v6, 4wd, 4door, 4-wheel disc brakes.

attempted to replace the right side upper ball joint.
(will be replacing both uppers and will be doing all
tie rod ends).

[front] frame on jackstands. floor jack up under lower
a-frame and jacked up fully to unspring.

removed cotter pin and loosened ball joint castellation
nut a couple of turns. inserted ball joint separation
tool (fork style) and hammered all the way in.

balljoint stud didnt budge from the steering knuckle :(­
i pryed up and down on the fork with no success. i
litely tapped (horizontally) on the knuckle in hopes
of "vibrating" the balljoint stud loose. no luck.

searched google for "tips tricks remove ball joint" and
didnt turn up anything more than i tried. i've done this
job on other vehicles in the past with immediate success.

... any tips/tricks y'all might know about?

 The only trick I know is to use a bigger hammer. Seriously, the last
one I helped on needed a 10 lb hammer to move it. A 5 lb might have
done, but the smaller ones were useless.

 If you mean pulling the ball joint stud out of the steering knuckle
there is an easy way. You need two good sized hammers. Put one hammer on
one side of the socket on the knuckle. Now take the other hammer and hit
the opposite side of the knuckle. (Like you were trying to crush the
parts) Give it a good whack and the stud should pop loose.

... interesting indeed - so i take the two hammers
and hit both sides of the knuckle at the same time?

... use a big hammer, "where"? on the knuckle?
the ball stud?

i hammered the fork (ball joint separation tool)
all the way that it can go. i even pushed UP and
DOWN on the fork's arm.

oil is a good idea!!

 When I replaced the CV boots on my '94 Rodeo all I did was tap the
side of the knuckle to jar the ball joint loose from the taper. I
left the suspension "hanging" though... removed the cotter and
backed off nut so only couple threads were engaged to support the
lower arm until I could put the jack under neath and relieve the joint
once it loosened.

It was not a light tap, no not at all. I used a 5 lb sledge and
whacked the knuckle pretty good around the taper several times and
had a pry bar in there to help it along too. I also think I used some
penetrant the night before, although I don't think that mattered too
much. Didn't even scratch the BJ boots... went right back together
and it's working great even now.

... well, you've provided a second reference to whacking
the knuckle itself, so it sounds like my second try needs
to involve smacking the knuckle ... thanks for the hint!!!

No, just hold #1 *against* the back side and hit the other side with #2.
Less chance of missing that way.

I like this!... the energy of the blow is transferred through the
knuckle and absorbed by the hammer on the other side. Very little
energy should transfer back into the car through the suspension
components, possibly stressing other parts and bushings!

If there's a next time for me, I'll have two of these hammers when I
do this!

... good information on the cast iron knuckels versus non-cast !
