Lets just say there's a reason I hate all things jeep. Or should I say Chrysler. My ram has beefy unit bearings and they suck just as bad. Fords don't have near the problems.
They are plenty strong for the stock sized tires and wheels that they're designed for. Unfortunately we feel it necessary to use tires and wheels that are way beyond their capability of handling. Don't ever expect a profitable manufacturer to go above and beyond the minimum requirement for safety and longevity on a part that they can make even more money on replacing.
Instead of replacing them every couple months, spend that money on a wheel that fixes the problem right by bringing the centerline back in to lighten the load on the bearing.
If I had the time I'd find a machine shop to make me a couple hundred spindles that bolt into the unit bearing flange on the knuckle and uses oem 1/2 ton Chevy or ford hubs and rotors. As useless as that solution is over swapping whole axles I'd probably make millions off of it from guys that can't or don't want to pony up the coin to do an axle swap.
