I have a 2014 gmc sierra sle 1500 and I bought the A- premium upper and lower control arms and the ball joints are too fat to fit in the spindle holes. I even went and bought another set of 4 ball joints and they measured the same size and the ones that came on the A-Premium ones. So now I don't know what to do. Like I'm so confused on what the problem is.

Is your knuckle steel or aluminum? How about the arms you took out, steel or aluminum?

Which going off of the "A-Premium" website, I think I know what probably is going on. You have the wrong arms most likely. You need the cast/forged arms for the steel knuckles. The aluminum and stamped arms use a larger ball joint as the hole on the aluminum knuckles and the 2016.5-up knuckles for the stamped arms.

They are out of stock on those.

Sometimes it doesn't pay to shop as cheap as possible.

Yeah I know cheap isn't usually good. But everything fits perfectly! EXCEPT the tapered part on the ball joints are too fat. And I have the original ( well I assume original) cast iron ones on the truck but I bought the stamped steel ones a.k.a the ones that I'm having a problem with the ball joint size. But someone told me try ball joints for a 2012 cuz they are skinnier but to also make sure they are ones for stamped steel arms. Or I'm thinking I might just have to buy all bushing and ball joints to change on My cast iron ones. I was just trying to also make it easier by changing the whole arms.

You bought the wrong arms. Return them and get the correct ones. You need the arms that fit trucks with the cast/forged factory arms. The uppers are the same GM p/ns as a 07-13 truck that has cast/forged arms.
