Hey everyone, kinda feel dumb asking this question because I thought it would be straight forward. I have had some clicking in my BB so I decided to try and take it apart to regrease and see if a bearing is blown. I was able to take the drive side crank off but the non drive side was like stuck in place. I thought it pushes out so I tried. I even took a mallet but nothing. Do I need a special tool to pull the crank out? Or is it just very badly seized in place?

Thanks!

Do you have a picture of both sides?

Might need a crank puller - also has a threaded bottom bracket.

Im assuming this is the entry level build.. Do yourself a favor and upgrade from the stock bottom bracket and cranks - sx stuff is heavy and clunky. Your right, bottom bracket likely failed. Sram dub stuff is a lot lighter and wont fail within a year. I replaced a freinds on their stumpy alloy with gx cranks + a dub bottom bracket and I believe it was over a pound of weight savings.
