Lower control arm wishbone question 09 X5 4.8i

[MrGBMWX5]

Any insights on the bushing difference?
Removed wishbone from driver side as it is squeaking. The bushing that goes into the wheel carrier / hub housing has a straight fitting.
Bought replacements part form after market bmw shop. This one has a tapered fitting. Cost 110.
From dealership part # is 31-12-6-771-894 or 893 one is right side other one left side. Cost 500+.
Had to put it back together as it is not going to work, but all the ones I see are tapered so now thinking the straight bushing is part of the wheel carrier. Does anyone know or can share intel since I don't want to take it all apart just to find out.
