Fixed a creaky bottom bracket after three tries with a new torque wrench
I mean, this old Trek 520 came in with a noise you could hear a block away. I cleaned and greased the threads twice, but it still sounded awful after a few rides. Finally grabbed my buddy's Park Tool TW-5.2, torqued it to exactly 35 Nm, and the creak was just gone. Has anyone else found that a specific number on the wrench makes the difference with those square taper ones?

Hold on, regular wrench as in just tightening until it feels tight? I'm genuinely shocked anyone would risk cracking a crank arm like that. Square tapers are surprisingly fussy about exact torque, and a few Nm difference can make or break that interface.

Wait, are we really out here using torque wrenches on square taper cranks now? I've been slapping them together with a regular wrench for years and they're fine. Sounds like you just needed to crank it down harder the first time.
