Why wont the bolt on the torque sensor stay tight on my rotor? Everybody l've talked to says don't put lock tite on it, but it's gettin old tightening it up every couple hours.
Thanks. Mike

How many ft. Labs. Of torque are you putting on it? If I remember right, it is a lock nut. May need replaced. MACK

I've never heard of that happening. My guess is that you have something wrong inside the torque sensing hub, like maybe broken ramps or something. Darrel

I don't know how many ft lbs. I just tighten it as tight as l can get it. Dad's R52 has the lock nut but the 72 has a bolt with a grease fitting in the end. Everything inside is in good shape.
