I just a little up close and personal maintainence on my f4i, as I do periodically...oil change, chain cleaning, chain tension etc...anyways I noticed that the torque to loosen the axle nut was really high. It took a lot of force to lossen that thing, which got me wondering. the last time it was torqued it was done by a shop following a tire repair. Do shops actually follow the torque recomondations, or just reef on that shit till they think its tight? I torque it to 69 ft-pounds according to the shop manual, and have never had a nut back off and wheel and chain slack increase. Do shops know something I dont?
