I finally put my sliders on today when I was changing my oil.... Anyway, I set the torque wrench to 30ft/lbs and it didnt click yet, but it was getting real tough to turn and then all the sudden, it got easy again even though the bolt is real tight. The slider on the right side (if sitting on bike) can spin by hand if you grip it real good although the bolt wont budge. The same happened on the other side. Is this bad or is it normal?
