When I installed my shimano 105 crank awhile back, I didn't take much notice to the 'raised' spline. As I remember it, I just moved it to a position that seemed to fit. Is it easy to misalign the splines on those cranks?

The reason I ask is because I am getting this sound from what I think is the crank. It's a mix between the sound you'd hear if you threw a penny at an aluminum frame, or think of it as two small pieces of metal pressed together VERY tight, and while they're still compressed, move them across eachother. It happens SOMETIMES when I pedal hard, or go over bumps. I just hope I didn't install the crank wrong, it seemed like a very easy thing since I just fit it on there and put the bolt in. Also I didn't grease the inside of the BB spindle, should I have done that?

did you torque the crank bolt to Shimano specs?

i had huge trouble with my 105 cranks because they'd been mis-installed. the splines weren't properly lined up, eventually wearing down, stripping out, and slipping. so yes, they can be installed improperly, and yes, it causes large problems. not sure if your noise is related to that. it seems silly to ask, but are you 100% positive the noise is coming from the crank? i've been convinced i'd toasted a hub only to find it was a creaky chain...
