Front Suspension Control Arm problems of the 1998 Subaru Outback

Sounded like there was a pop in my front corner. Still drove ok under 20-25 mph. Faster than that the wheel shook violently. Backing up there was a loud grinding noise. Took to friends hose who works on cars. He said it was my front lower control arm on the driver's side. The connection between the control arm and the front (he called it handling bushing) was rusted completely in two. He found a used control arm at a junk yard and replaced it for me. We took pictures of the part that I can provide if needed. I no longer have the old part.
