Hello, I'm in the process of replacing my left lower control arm and ball joint (BJ) All was going well until it was time to remove the ball joint.
Since I was replacing the ball joint I wasn't concern about any damage to it, so I tried to knock it out of the part pictured with no luck.
As you can see I was able to remove the nut from the bottom of the BJ, but could get no movement at all when trying to hammer it out. And this is with the lower control arm completely removed. I actually ended up cutting the BJ off w/ a cutoff tool, and what you see pictured are the results. It looks like either
the BJ got seized inside of the hole (more likely) or it was part of the original part (#2102201)? All my research shows the BJ being a separate part, so I don't this the latter is the case? Either way, I'm stuck trying to remove this BJ from this part (see pic4 for close up). Any ideas would be greatly appreciated?

BJ is a separate part and can be replaced independently.
Look like you need a new LCA and its associated parts.

Did you check this?


If there’s an Autozone near you, rent every type of ball joint separator they have. You might try a combination of penetrant, heat and vibration from a multi-tool like Kent Bergsma does. If the knuckle can properly supported, try a sledge hammer on the flange that receives the ball joint post. Smack it transverse to the post. That might momentarily deform the hole enough to dislodge the ball joint.

This is when you bring out the TUF....The Unfucker. That's my affectionate name for my 26lb sledgehammer.

If you already have the whole knuckle out, then use a shop press if you have access to one.

Steering knuckle?

thanks. Now I have to find a way to extract the stuck piece of the ball joint or maybe try drilling it out? I don't want to spend $400 on a new steering knuckle if possible.

Yes. I will try the sledgehammer since it's still on the car.

I just had mine done - and my mechanic said unlike my W124 and R129, you do not have to remove the lower A-Arm. When I went through that on my W124, it cost the same to buy the whole assembly vs use a press to punch out the old ball joint.

I don't know how he did it but apparently the factory listens to the shops.

The attached pictures show what I used to remove my ball joint and tie rod end. You keep torquing the removal tool untill "BANG" and the parts break free.

This may still work for you if there's enough bolt to grab on to. Otherwise, bring it to a local machine shop and have them press it out.
