OoPpSs wrong sub forum.
I'm going to repost in "Stock Problems/Issues"

We tow our 05 MCSa behind a motorhome, front wheels on a tow dolly.
Which puts more pressure AND miles on the rear bearings.

Are the rear wheel bearings sealed or can they be serviced?
I would MUCH rather do a little preventative maintenance than call a tow truck in the middle of Wyoming or Arizona, etc.

Thanks

They are a sealed unit and are replaced as such. There really is zero maintence that can be done to them sadly, but if you can do a rear brake job, then you can easily replace them if need be.

Backside of wheel bearing/hub assembly: (you can actually see the heat marks on the hub face from when it was pressed together.)
