Hi folks. I've been a lurker, first time posting on this forum. I have a 2011 X5 with the N55 that I am repairing after a front end collision, vehicle is for myself.

I have no idea what the previous driver hit, but some of the impact was absorbed by the crankshaft (through the vibration damper/hub).

I initially replaced the damper, and noticed that there was still a "wooble". Here are some slo-mo videos

So my next step was to replace the crankshaft hub. It is better now, but there is still a "wooble" present. It seems much improved however.

What I dont know is if there are going to be any negative consequences down the road if I do nothing else, and leave it as is to drive. My concern is that there is a slight deformation in the end of the crankshaft, and leaving it alone would cause additional stresses on the surfaces the crankshaft rides on.
