I have a Felt FC frameset with a 2012 SRAM Force crankset (BB30) that has been making a hell of a lot of creaking/groaning noises over the past few rides. I'd like to check out the bearings to make sure they are intact and hopefully just add some grease. How do I remove the crankset? I've never removed one before, but would love to learn. Do I need to use a pin spanner on the non-drive side or can I just use an allen key? Any advice would be greatly appreciated.

Thanks in advance!
