WTB rear axle housing, 2000 dually 4WD

[lifted_up]

It's been feeling like I've been dragging my trailer or my brakes are on for a week or so and has gotten worse. checked all the bearings and brakes and they seem okay, it looks like I may have warped my axle housing. Anyone have a spare? Looks like I should have put the traction bars on the day they were delivered.confused:

I plan on converting to a dually at some point. Let me know how it goes.
