I was pondering the Stronger Jeep hub thing and came to the conclusion they could cause U-Joint failure. We all know the HUBs are the week link in the drivetrain. They function as a fuse to protect the axle shafts and other drive train components from being overstressed. As such if you run Stronger HUBS you will risk the chance of U-joint failure. On a scale of 1 to 10 replacing a hub is a 1 while replacing U-joints or even swapping in a trail ready spare is a 10.
And with Warn the warranty is great so replacement should be great in either case.
