Rear axle

Anybody know what the rear axle in a 2019 is rated for?

 

Usually ~4200 lbs. On paper, anyways...

I should add that depending on you cab and bed configuration, the axle rating is usually 300-500 lbs greater than you max payload on the door sticker. The weight of the vehicle on the rear axle is usually about 2700 lbs.

 

Purportedly the axle is rated somewhere in the range of 5500lbs. That info came through someone that had a relative working at the Hino factory in which they are produced. Given the axle shaft and tube diameter, it’s not out of the realm of possibilities.

 

Interesting info. My drivetrain specialist friend would agree. His opinion of it put the capacity above a semi floating 14 bolt rear end (6 or 8 lug) but below a full floating 14 bolt based on bearings, axle shafts, and housing. My real world usage would also agree. My buddy showed me bearings and axle shafts from 3/4 axles he had kicking around and compared them to the tundra's, then laughed at other 1/2 ton axle bearings as they appeared comically small. Then he cursed at me for making him pull the center section out to install an Auburn. Then he made me hold it up there while he "forgot where he put some stuff" while reassembling it.
