Shoulder Harness Height Adjustment
The adjuster heretofore always moved smoothly and crisply from one position to another. But here lately, it has become balky: it is especially resistant to movement from the highest setting to the lowest ... it doesn't just slide smoothly as it formerly did. I have, thus far, been able to jiggle and strongarm the adjuster to lower it for my wife, but I fear messing something up inside the mechanism.
So my questions are:
1. Will a spray lube, such as Fluid Film, resolve the adjuster's balkiness?
2. Will a spray lube, such as Fluid Film, just make things worse?
3. Is there something on the backside of the adjuster ... something inside the door frame ... that is wearing out or needs replacement parts or needs some other form of service?
I appreciate your thoughts and suggestions.
