Adding to my own thread as I'm now 1/2 way through doing the bearings (and brakes) again. For new readers that may be seeing this for the first time, my '19 315RLTS suspension is a MORRyde IS and it has Kodiak disc brakes.
FYI, the last service was 22 Feb 22 (27,661 tow miles on trailer at that time). Today is 29 Nov 23 and total mileage is 41732 (so 14,071 miles since last service).
The street side inspection and service is complete. Bearings and races look and feel perfect--no issues.
Gee whiz info:
For those who may remember the problem I had with the Caliper Guide Pins "frozen", I found that this time they were moving freely. (Yea!) Unfortunately there is still more wear on the outboard pad than the inner pad. :(
According to the box the new pads came in, there's two potential issues going on with the brakes (annotated below the pic below).
There's definitely a "Step in lining" issue with the outboard pad. I've already replaced all the hardware (last service), so that's not the issue.
The other issue is the "Only one side worn" issue. At this point it appears to be the caliper piston. But--all four brakes have a bad caliper piston??? I tend to think it must be a single-source problem, just not sure what that source of the problem is.
Both problems are nuisances, but do not affect brake performance. The disc brakes are strong and brake performance is checked prior to departure each tow day. Last item on the pre-departure checklist.
Finally, there was some concern about the "witness marks" on the disc, but I think they were caused by the (very) short movement of the trailer to center it in the driveway. The trailer has sat since 17 Oct (it was moved on 28 Nov).
If there's anything of substance found tomorrow I'll add it in another post.
There's a PDF attached that I made for myself. Posting it in case there's something useful in it for someone else. (I tend to forget stuff when the time between services is so long, so this document is in lieu of good brain cells. )

Gee whiz info:
- The MasterPro 412920 seal (O'Reilly Auto Parts) is a relabeled Timken 412920 (referenced in post 29). See https://cad.timken.com/item/seals/oil-seals-inch/412920
- A cross-reference of part numbers to the original Dexter 010-036-00 is here: https://www.trailerparts4u.com/files...hart_11-11.pdf
- The installation direction of the MasterPro is not obvious (to me). On one side there’s a slight raised rubber lip. This side goes on the AXLE side. The other side of the seal the rubber is slightly indented. That side goes against the bearing.
- Direction of installation verified with Timken customer support.

- Note to Country Campers -- the controller level was lowered to 6.5 from 7.5 as you suggested quite awhile ago.
