Left side upper ball joint thread in just fine by hand initially, I cant even get it started on the right. A turn of the wrench is very hard and I'm assuming its cross threading. I got a picture of what I think is the culprit. The top thread gets basically cut off and flattened. Is it time for a new UCA, or should I just wrench it in? Dosent feel right to wrench it, and dosent look truly square.
