Dear friends, my front control arm finally caved in after 181k miles of service and needs replacement. After reading tons of DIY related thread, I am still nervous as heck. Please help me with some questions:

1. Is the front control arm located behind tie rod and in front of tension strut (upper control arm) for xdrive car?

2 Do I need to detach the whole headlight leveling module (rod and sensor) or just the headlight leveling rod before starting work? Do I need to order new headlight leveling rod?

3. Gonna get Pittman arm puller to drop ball joint part of the arm. What to use if the bushing end (end that attach to the subframe) is stubborn?

4. Is there enough space to get an impact wrench in to remove the ball joint and bushing nuts?

5. Do I need to get new locking nuts for control arm?

Thanks in advance. Please help my car join the 200k miles club.
