New hub doesn't fit 2016 sierra 1500??

[Troxic]

Hey,  I'm trying to replace my hub but every one i buy doesn't seem to fit over the lower ball joint. The original hub has a bigger hole to accept the lower ball joint but everytime i ask for a 2016 gmc sierra 1500 4x4  hub it doesn't fit what gives?

Are you talking about the knuckle? The hub has the bearing in it.

Yeah the steering knuckle

OEM or aftermarket parts?

There are two different knuckles.  One for cast/ control arms, one for aluminum/stamped steel control arms.  You need to know what arms you have in order to get the right knuckle as the ball joint stud sizes are different.

Mother clucker... that could be the issue.  Thanks alot!!

Is it possible to swap out the knuckle without affecting other things such as the existing hub assy not lining up correctly to the new knucle?
