Premature wheel bearing failures.

Depending on your roads...............(when I was young I navigated LOTS of narrow county roads, and would often have the right side off the pavement on the shoulder)

Severe wheel offset?
Tire balance problem?
Bent wheel/ out of round, etc?

I've never liked those types of bearings, and Mopar was the first to use a similar type, back WAY back when "full time" 4x4 came out. The problem with them is there is no way to properly lube/ service them, you cannot replace the seals, but worse, there is no adjustment and the bearing "halves" are WAY too close together, increasing the leverage against them from the wheel/ tire
That happened in 1975 thru 1979. I replaced a ton of them. They suffered poor *** quality metal in the hub that the dual bearings pressed on to. Finally changed back to normal in 1980.
