Trailer bearing help?

[Skypilot]

Have a dual axle Triton trailer.....a bearing "window" on one, I noticed on returning from the lake, is popped out about a 1/4"...Do I need to add oil? Check? What do I need to repair?
Thanks

Did you find any info in the trailer manual? Should have been a manual just for your oil filled hubs.

Set the hook.

don't know how the trailer is made but if the window is popped out I would not take any chances and replace it before it starts
to leak. the window is there so you can see the oil level, should be about half way up the window ?? mine has a cap that screws out. chances are if it has popped out it is leaking
