    I'm trying to finish installing my SPC UCA but the upper ball joint pin keeps turning when I tighten the castle nut (see pic below). Is there a way to hold it in place so I can tighten the castle nut?

    Gotta put enough pressure in the taper so it “locks” in to tighten. Maybe try jacking up the lower control arm and pull down on upper arm while you tighten the nut. Sometimes there is also an Allen you can stick into the threaded end of balljoint and use box wrench.

    It spins if you use a box wrench, use a battery operated (not the super heavy duty ones) impact it’ll go on.

    list is growing fast
    Impact gun will do it. Or use clamping force to get the taper to bind and it will go. Gl.

    I ran into this when installing the nut. I used a ratchet strap around the spindle and anchored the other end to frame in the rear and ratcheted the strap enough to put pressure on the ball joint and I was able to tighten the nut and torque it. Was it the ideal method? no, but it was all I had at the moment and it worked.

    Thanks everyone! I was able to tighten the bolt by jacking up the lower control arm and pulling down on UCA with all my weight as I was tightening the castle nut. It worked! Didn't have this issue on the passenger side, torqued it up just fine. Although getting the long UCA bolt out was a PITA on the passenger side. Anyway, this job took way longer that it should have... My front suspension is finally finished. Ya'll are awesome!
