You can replace the wheels with tapered lug nut style wheels as long as they have the 4 / 156mm pattern. The 4 tapered lugs will locate the wheel on center to the hub.
@@M3OffRoad I should have also pointed out you will need a set of 12x1.25 tapered lug nuts as well since the factory nuts will not work with tapered nut wheels. Plenty of them available on Amazon and other sources.
That means it pulled out. Jack the rear up and take tension off of the axles. Try to move the cup back and forth. If it moves then you need new snap rings
