I just did this last night(on jack stands and ramps!).
I was also doing the sealing sleeve because that was leaking. The BMW tech page is in a PDF online for that. I will add - for the sealing sleeve, I marked the 6 o'clock position on the edge of the new sleeve so it went back In the same way it came out. Saved some frustration since that is a small work area.
Great DIY. Thanks for taking the time!
