Looking at a 74 dart, has had k-meber swapped after front suspension failure(???). Currently V8 K-frame, I pulled engine to go through it, and noticed passenger side lower control arm is slid back, almost off of pivot shaft. How does that even happen? I can see I will need to go through this front end, but real curious as the previous failure was said to have occurred on this same side, where entire wheel came off! Any ideas?
