7.5 months into preloading at UPS, just recently my knees and hips make a cracking noise everything I bend down or squat. It doesn't hurt but very noticeable Has this happened to you guys before? And what did you guys do to fix it? I've seen many drivers in my hub with knee sleeves, should I get one? I was also told by Hr when I was hired to get one of those soft insole things for my boots? Will it help?
