Thank you for your help. I installed the new crank today and the chainline matched the rear cog. Now, about the crank arm on the left side (non drive side). I noticed that it's not as deeply inserted as the right side, although both sides are at the same length with the frame. Are both sides supposed to be the same distance? Also, how much friction should there be when you spin the crank? Should you grease or lube the inside the BB cup? I only greased the threads.
