I think I know which one you mean as I remember having difficulty! You may be able to angle an object if you have the heavy lift perk. Completed this on Wednesday, I think my game time was around 24-25 hours. Took my time and only missed 2 side missions, one of those was because the game actually broke unfortunately. I didn't use any of the lethal weapons, only on bosses. So will be playing through with the lethal weapons again soon.
