The bottom bracket feels like it's wobbling and I wanna replace it before it gets worse. This is on a Diamondback Outlook mountain bike, prolly a 1997 or 1998 model. The bottom bracket literally broke while riding about 2 years ago and was then fixed by a local bike shop (LBS). Now it's wobbling. I'm new at this and I guess I need a crank puller and a bottom bracket bolt that you twist with a wrench?

It looks like I'm gonna have to remove the old one just to see what size I need so I'll know what to buy before I can actually do anything. I'd like to get a sealed cartridge one.









Thanks!
