An old fleet mechanic told me I was overtorquing wheel bearings wrong for 4 years

Honestly, I've been spinning wrenches on class 8 trucks for about 4 years now. Last month an old timer watched me set bearing preload on a steer axle and stopped me mid-turn. He said 'you're crushing the cage, back off a quarter turn and feel the drag.' I was cranking them down way too tight, thinking tighter was safer. Now I do his method and the hubs run way cooler. Anyone else get called out on something they thought they had down solid?

Wait, did anyone check if your torque wrench is even calibrated right? I saw a guy spend years overtorquing everything because his snap-on was reading 20 lbs high.

Yeah I used to never think about calibration but that story kinda changes things for me.
