Front end not level

I did, post #3. “Torsion bar socket broken loose from the crossmember.”

It definitely does happen, and the rust doesn’t necessarily need to be that bad. The factory welds on some of the torsion bar anchors were pretty bad from the factory, so in some cases very little rust can cause the welds to fail and the anchor to spin.
yes, I see. I just skimmed the replies, and thought you were referring to the front anchor, probably because when I think cross member I think trans mount, not torsion bar anchor. You say tomato....
Another remote possibility , maybe someone mixed up the torsion bars: left where right is supposed to go, and vice versa. Or mismatched t-bars.
