it is a torsion
axle, I have to pull it apart again to get pictures of the assembly< but from the outside of the wheel there is a cotter pin , a nut , a washer a roller bearing then a cone then a grease seal. all were in good shape no grindings or loose bearings and it assembles tight1 also their is drums and
brakes on the trailer that havent been active in years,(i am just leaving them alone) any info would be appreciated!
