Why does it seem like wheel bearings on trailers need constant maintenance, but the ones in our cars don’t?

141 views

For example, I know a couple people with trailers and they all talk about regreasing their wheel bearings and removing them from the trailer on a somewhat set schedule in one way or another, but I’ve never heard of that being done on a car.

What is the difference? Are trailer wheel bearings just made poorly?

You probly live in the city, roads are nice, always paved. Trailors have to travel on bad roads and get a lot of wear and tear, going to construction and industrial sites etc. I live in the country , on an unpaved road. Trust me, I’ve had my wheel bearings on vehicle replaced twice in 8 years. Its just about the conditions of the roads the vehicle travels on.
