MAYBE unrelated, but STOP THERE AND FIND OUT WHY? Something.........wrong bearing combo? Something worn in a hub. Oddball hubs, some "conversion?" THIS SHOULD NOT EVER BE NEEDED
Years ago I looked at a truck for a guy, one spindle had been replaced. Turns out there is a "light" and "heavy" duty, and he ended up with one of each, and the TOO LARGER INNER BEARING bore was slopping around on the back side causing problems. Had to "fix" it all over again---go out and find a correct one.
