Lower ball joint press fit question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**chev-obsession** · 12-09-2021, 02:34 PM

I am installing new ball joints on my 69 c10. Using 72 ball joints and spindles. The new ball joints fit into the spindle well, and they are knurled on the press fit side. I did some measuring before pressing in the new ball joints and have a question before I potentially get into trouble. I did get 2 different ball joints that Napa listed for this truck. One was “standard design fit” and the other was “oversized fit” and they both measure the same on the knurled (press fit side)

The opening on the LCA is 1.958”
The new Napa ball joint is 1.982”
The original ball joint is 1.972”

Is that an acceptable press fit on the new ball joints and LCA?

If not any tips, advice or other info is appreciated.
