My Snap-on guy sent torque wrenches out to someone else for repair and calibration. You might be better off sending it directly to the outfit that does calibration, no middle man and they will listen to you and answer questions directly. They will also provide a certificate of calibration if they are reputable and you request it, so you know you aren't getting duped by dealer who's just bending the springs around with a pair of pliers to make someone happy. If you drop a Snap-On torque wrench, parts repair and recalibration isn't covered by Lifetime warranty (read the fine print in the catalog). I once accidentally knocked a click type TQ series off the bench onto the concrete floor and something inside broke. You could hear it rattle inside and the dial didn't read properly . It cost me $65 to fix.
