Looking to address the pinion seal leak on my 135i. I can get the 50mm insert nut off, that is pretty standard. The one that needs special tool is the 12 teeth (red arrow) giant nut that holds the preload.
Before I spend $200 on ECS kit on the link below, wondering if you guys have one that you want to sell or if you have done this before, I'd be interested what tool did you use.
