I have never had a car bearing failure. A trailer (ok, my trailer) is much heavier than any car I've ever owned, hence I draw the conclusion that a trailer is different because of its weight.
I can't wait to see the laughing head-scratching icon in the reply to this.
Not necessarily..
My 2013 F250 4x2 with 6.2 IS RATED 4,200 lbs (GAWR) ON THE FRONT AXLE.
A F350 4x2 will have a front axle GAWR a bit higher and add in a Diesel and that front axle is going to take a beating..
I am not sure what you think big rig tractors use for front wheel bearings.. As a hint, big rig tractors are NOT front wheel drive..
Folks that IS the same as a trailer if you really think about it..
A dual axle trailer rated for 7K-8K will typically have TWO axles rated at 3,500 lbs GAWR..
In a nutshell a VEHICLE axle can take as much if not more weight (or abuse) than a trailer axle.. AND non drive axles on a vehicle USE THE SAME ROLLER BEARING SYSTEM.
