So I noticed a very slight bit of grease mixed with dirt caked on the back of my hubs at the seal last time out. I am not overly concerned, but I am quite sure it's time to repack the bearings and put new rear seals on.
The trailer is 5 yrs old now and I have only repacked the brake axle 2 yrs ago, but keep the hubs greased through the bearing buddies religiously. It's running fine but my feeling is that some preventative maintenance would be a good thing. Last haul the hubs were barely hot when I pulled up to the lake.
I have one extra bearing set in the garage.
My questions are:
How long do these bearings last?? Should I replace the whole lot just for the sake of thoroughness?? Or should I simply pull them, inspect them, repack and put them back in??
Obviously I would replace any visually worn bearings. I think my brakes could use a bleed too.
