While removing a stubborn lower ball joint, I accidentally got the press a bit off center and managed to lightly carve a bit of thread grooves into the seat where the ball joint sits in the axle C (I hope that's what its called). Should I grab a rounded file and try to smooth them out? I don't wanna accidentally file away too much material as to the ball joint would be loose somehow. Any advice appreciated
 
If it does go in loose, you can dimple it in a crosshatch pattern then apply loctite 680 retaining compound and press it back in. Also, as you are pressing in the new ball joint, whack the C with a hammer which should help drive them in straighter since it will release any bind.

Yes I would dress any raised material prior to pressing the new joint in.

This works well and IMO is a better solution than those knurled ball joints out there.

I think what you are concerned with is the damage and I would just smooth and reinstall you didn't do anything detrimental
 
I’d clean up any burr that you lifted into the ball joint hole, then install it. If it feels like it presses nice, run it. If it feels loose, pull it back out and dimple the bore and use the locktite

Why clean up the unintentional burr when we wouldn't clean up the intentional dimples?

Here's pics for reference. Seems better to smooth out with a file instead of just forcing it in, but then again I started this post because I didn't know the best approach. Interesting to see the differing opinions

If one were to dimple the ball joints to correct a loose fit, this is what it would look like.

Can you see why I question the value of you trying to smooth out the damage? The last thing you want to do is make the fit even worse.
 
I understand the concept you are after. Im just questioning whether it is a good idea to try to force the ball joint into the space with the thread scars being raised a decent amount above the surface of the rest of the seat. I haven't yet tried to put the joint in, so the fit may be ok, even with grinding down the scars. Just trying to get a consensus from the community

Anyone who says the scars should be smoothed needs to explain why the same wouldn't be done to the dimpled ball joints.

Is there any evidence that dimpled or knurled ball joints could damage the inner surface of the ball joint holes?

Knurled BJs are famous for it. The entire concept of dimpling is a corrective measure to make a ball joint fit into a damaged yoke by raising the surfaces to re-establish an interference fit. Stuff is going to get mowed down again in the process of installation.

Okay, correct me if I'm wrong, but:

Both knurled and dimpled ball joints stretch the ball joint hole, on purpose. That is their way of fixing a damaged inner C.

Would then a normal ball joint in a scarred ball joint hole do the same thing?

You think the little raised burr is going to win the battle?
 
Ask jcw if the ball joint sustained similar damage.

We won't know unless he installs new ball joints as is, and then removes them.


All I'm trying to figure out, is whether we can equate dimpled ball joints to a scarred ball joint hole.
 
Why clean up the unintentional burr when we wouldn't clean up the intentional dimples?

For me, its the intentional vs unintentional. You're probably correct, it will displace the burr and be fine. However, If I'm doing it, I'm going to apply the dimpling evenly to make sure there isn't any change of the displaced material "biasing" the fit of the joint. In fact, if it were mine, I would clean up the raised material and then dimple the ball joint if I needed too. That's just me though...I've never been the most efficient mechanic.
