Tubular A-Frames - dangerous - see link below

Classic sh!t Chinese ball joints.

Finally putting it together. Got the spring in, put the spindle back, snugged up the nuts on the ball joints, did not tighten much at all - figured I would get weight on, bounce the car up and down a few times and re-check to make sure they seated well and then tighten up - never got there. Both nuts spun right on clean. Put in the cotters, slowly let the jack down and the nut on the bottom ball joint sheered right off from the spring pressure. Sheered through the cotter pin too. I had not even backed off the spring compressor yet. Just a loud pop...

These ball joints are f@#king dangerous. I can only imagine if it had held initially and started I driving - possible death situation. My son drives this car too.

I should have listened to others and gone straight with some Moog ball joints. I thought, well, cash is short, they should last a while. I never even considered the damned metal in the stud
to be so bad that it would pop.

These should be outlawed as they are a serious hazard with those ball joints. I only hope the rest of the construction is safe.

Damn! Glad you weren't injured just putting them in. Glad you posted your experience. Stay safe.

I ran those on my 71 but the balljoints had so much play they couldn't align it. Had to put moogs in. Had a CPP pitman arm, brand new, in my 56 straight up break (ball weld broke and dropped out) after 500 miles earlier this year.

Oh Snap!!
Does it take the standard ball joint per vehicle?
I would also keep and eye on the control arm welds after you have been thru a few road hazards.

Scary stuff. But is this really a surprise from ebay bargain parts? caveat emptor.

Bowties are for Pee-wee Herman. "Chevy": even the name sounds cheap, but not as cheap as your Pontiac will be with an LS transplant.

That's why I asked around about them ahead of time Phil.

People did say the ball joints could be an issue but, like I said, because of lack of funds, I went with them thinking I would get "some" use out of them, but no, they were plain junk and a serious hazard.

New standard ball joints are in, the car is rolling and feels great even though I haven't had an alignment yet. Making apt. for that today.
