does anyone know what size drill bit to use to make the rivet holes bigger for the replacement ball joint mounting bolts?
also is it normal for the new ball joint bolt holes to line up with the control arm holes?
thank you

I have never drilled any out either. Grind the head off the rivet and drive it out with a punch, then bolt in the new joint.

I've never had to drill any out, except for my new SC&C control arms. They came in drilled for the newer style "metric?" balljoints. The holes were "oh so close"

Are you positive you got the right ball joints?
The right ones should just drop in, bolts and all.

Ball joint hardware is 1/4 inch diameter. As said, should fit.

If not, one can use a 9/32 inch drill bit to clearance the holes for a 1/4 bolt.

They shouldnt have a ton of play, but there is definitely enough clearance in the upper ball joints to be able to put them in place by hand. That's why they use mounting hardware (rivets/bolts) rather than press fit.

My brother installed new ball joints in my car tonight. I bought MOOG brand from O'Reilly's and there was NO drilling. They just bolted on.
That reminds me of a time when I jammed a lower ball joint in the press one time. Just needed one, so I went to the local parts store. The Duralast (A-Z) lower ball joint was waaaay too small. Went next door to O'Reilly's and their ball joint fit right. Not sure if the uppers are the same scenario.

Do you have the metal shell and boot over the balljoint? It all gets put together, and then drops down through the top of the UCA. If you are putting the BJ in and then trying to put the boot and retainer on from the underside, that would account for the slop in the fit.

Hi, I have a question regarding the installation of these ball joints. I have the bolt going from top to bottom, and I was told the it should be the other way around. The reasoning was that the grease cup will rub the ends of the bolt and break it. Does anyone know whether or not this is true? I cannot stand to see the bolts in upside down. Actually I had bought the rivets, but no one would install them. I'm still pretty upset about that.
