What would be the difference between the c10 and c20 lca's?
I do know the stem on the ball joint im trying to replace is the same size as the new ones.

C10 is 1/2 ton.

C20 is 3/4 ton.

I bet someone put a C20 arm on your passenger side.

Go to Napa and measure a 3/4 ton ball joint.

This came off the control arm and this is the driver side arm. The ball joint measured 1.90 and the hole is 1.80

The NAPA oversized measures at 1.78
Also, I ordered and installed c10 poly bushings into the passenger side control arm which I have the same problem with.  Aren't the bushings different sizes?

Dude!

How can a ball joint measure 010. bigger than the hole it came out of?

Dumb question but are you measuring the diameter at the same point on each?

Do you have before and after pics of the ball joints? this is getting very strange.

I would go to Napa and measure a 3/4" ball joint.

I tried closing them with a cold chisel and hammer after the new ball joints were lose by hitting around the outside of the socket.

I just bit the bullet and bought new control arms from  .  I'm not gonna chance it.

what i was thinking is that he measured the ball joint on the outside of the splines and when he measured the whole it didnt include the splines as they cut into the control arm
