New Wheel Hub loose after tighten the bolt Club Car

I am hoping someone can help me with an issue I am having. I just received two brand new wheel hubs that I ordered online for my 2011 Club Car Precedent. After putting the two wheel hubs on and tightening the bolt, there is still about an 1/8" of play. Is there a remedy like adding a washer?

The original hubs did not have this issue....I was able to tighten them until they would not spin freely.

Also, any easy way to pack them with grease?

Thanks
