Help, I can't get this blasted LCA ball joint loose



Help a brother out. This is the last piece before I can start putting everything back together again with a new LCA. I have used the tool, I have hit the stud with a hammer, I have sprayed WD40 version of PBBlaster, the ball joint separator is on there tight right now and I'm letting it sit, if I turn it too much eventually it comes flying off, Monday night I hit myself in the face with the end of a breaker bar when the tool popped loose.

Ideas I may try tonight (please let me know if these are terrible ideas)
  • Dry ice and try to apply it to the stud or the ball joint from underneath
  • A butane torch to try and heat the part of the wheel carrier that is around the ball joint.
  • Maybe a plumbers wrench, and grip the stud really tightly and try and turn it?

I really really need to get this out and get the car back together so I can take it to get corner balanced and aligned and get ready for a track weekend next weekend.

Help

Put some tension on that splitter and then hit the top of the bolt with the air-hammer with a couple of short bursts (put the nut on it first otherwise you might kill the threads) those tapered bolts are bastard to get out especially if there is any kind of corrosion happening in there....

The end of the threads are toast already and you should see the nut, it is like a ball of putty. I had to use a 3/4 socket to get it off since it was deformed and the 18mm wouldn't go over it.

I'll head out this evening and get an air hammer from HF, any special ends or anything to get or will the default chisel be just fine?

Any of these? Search results for: 'air hammer'

Let's assume the problem is corrosion?
PB Blaaster is O.K. but a google search suggests Kroil is better.
Whatever you use,patience & persistence are required. Tap it all around, put some more penetrant on,leave it for several hours -repeat.
Hope this helps.

If you are not going to reuse the lower arm and ball joint, use an old fashion "pickle fork" separator and a large hammer:



A couple of good smacks and it should let go.

By the sounds of it, its already FUBAR.... yikes...
Penetrating fluid, a little pressure from the separator or pickle fork and couple of shots with the 1" blunt hammer end of the air hammer and they pop 99.9% of the time.
Depending how much he widened the shaft of the bolt by beating on it, he might have to cut it off with the cutting wheel to get it through the hole now....

Headed to harbor freight now:
  • Air hammer
  • Pickle fork
  • Cutting wheel

Should come to around $15-$20 or so

And depending on which 20% coupon I can scrounge from my car magazine I'll have either a free flashlight (yay) or a tarp (moderate) or another measuring tape (I guess) or an electronic tester (I'll pass)

If you grind the finger of the ball joint separator tool where it hits the end of the ball joint, you might be able to make it less likely to slip off. On mine (not the same brand), I ground it flat - maybe a bit concave, and it stays put now. Also, the ground area isn't as slippery as the factory finish.

The ideas are all good. But i would say take a break, drink something, relax, than go back to work.

There is no need to hit yourself into your face more than once a day.

I just went through the same project, it's a real stinker (although that is not the word or words that I used). I used an impact wrench on the ball joint separator, and although it was a struggle, it did work. When the ball joint finally lets go, parts will go flying, so make sure you have your arms, hands, and feet positioned safely. One of the control arm went flying on my car, and smashed the stuffing (again, not the word I used) out of my finger.

I know that you do track days, so if you are going to get an impact wrench, why not spend a few more dollars and get a battery powered one? I have an inexpensive one (under $50), and I use it all the time. Since I got it, I never use my air impact wrench any more (no air lines to deal with, no noisy compressor to listen to). You can also take it to the track, and if you have to change a wheel, it's uber-handy. The electric impact wrench, along with my aluminum racing jack are two tools that every time I use them, I'm really glad I have them!

I'm balls deep with the loaner pickle fork I got from the auto parts store. Heading to HF now for a bigger one and an impact hammer. I'm going to try tapping on the top of that stud with the hammer, and maybe driving in the pickle fork deeper. I'm trying to figure a good way to counterhold the wheel carrier so it doesn't move as much when I hit the pickle fork with the hammer., maybe I will bolt back up all the suspension pieces (toe arms, track arm, and other end of the LCA, but I don't want to put too much stress on them. Although driving the car surely puts a lot of stress on them as well.

Got it back together on my driver side....

The SIR tool could remove the bearing if it had maybe 2-3mm of clearance on top of the parking brake shoes. I may rent a slide hammer from the auto parts store and see if I can pull the hub on the other just enough to slip the sir tool in there... And leave the parking brake alone
