My new used trailer has buddy bearings. On one tire, there is a lot of
grease spun out on the wheel and tire. The other not so much. I'm going to
pull them. What do I look for in terms of wear or failure? Do I spin the
wheel jacked up before pulling and listen for growl? Is the race pressed
into the wheel? Onto the spindle? I've done a lot of things mechanical,
but this is new. And what about the buddy bearings? I've heard both ways
on those.
