While I have no direct knowledge of what is actually done I wonder if Wayne may be preloading the front wheel bearings a bit like my X- Foretravel guru mechanic did for us?
It's not quantifiable as its a feel and experience adjustment.
Watched a video on how to replace the wheel seals by a seal manufacturer and the trainer mentions several times about the legally defensible .001-.005 play in the rotor measured at the edge after the process of preliminarily tightening and loosening of the bearings is done several times.
Problem was in my coach that that method left a dead spot in the steering. Coach wandered. At least ours did. Your results may vary of course.
Putting two and two together and getting my usual six answer I wonder if my new Michelin xza-3's straight ahead directional sipes they mention in their specs might be a design feature to help compensate for the verifiable play in trucks front wheel bearings?
If Michelin heard enough comments about steering wander maybe they figured out that part of the problem might be bearing related.
No real info of course just surmising.
My guy was trained by Foretravel long ago. Or figured it out by himself. Or someone else showed him?
My Honda motorcycles front steering tapered roller bearings have an adjustment procedure and a preload spec in the shop manual.
Obviously too tight can be a problem but I constantly check mine with a heat gun during driving breaks and no heating has shown up so I feel pretty good about the setup.
Did change to synthetic oil in the hubs at the same time.
Not suggesting anyone does something incorrect or unsafe or that they should do anything unsafe here but I have researched this a lot and my guru has fixed hundreds of wandering Rv's in his career.
Not having anyone watch may allow him to actually fix bad tracking coaches?
Potential Legal issues control a lot of things now.
The seal guy in the video mentions "legally defensible" several times. Read between the lines. He had a distasteful look on his face while quoting that btw.
