I think the problem is not so much that parts will fall off, more that the brake will start to act weird, binding and locking up possibly. I would like to see more official information about “secondary steps” beyond notifying Dexter for help....
If I find a nut loose and I tighten it, do I call it a day? Two nuts? Three? What if they are really falling-off-loose but I can torque them down satisfactorily? At what point does this become a real concern?
What happens next if I find a nut that will not tighten, indicating a stud that is turning?
Is it required that an RV tech do this recall? If a problem is found by an OWNER, will that affect Dexters response in any way?
It would be good to know where the limits are. If a significant number of nuts are found loose I would want to pull the drum/ hub off completely to clean and inspect the backing plate for trauma - cracks or bending. (These parts can be subject to very violent torque effects, especially if you slam on the brakes at freeway speeds.)
For those who want to have this done buy a shop, you could have a traveling tech come by your place of storage to perform the recall. Cost will be about the same as for an RV dealer but the hassle is way less, especially in winter. Google “mobile Rv service”. I used one last year to do the Inverter Service Bulletin and was very pleased.
