I installed the wheelers not too long ago, what I did was jack the front end up took the front wheels off and let the suspension droop as low as possible. I used a large adjustable channel locks and they came off easy. To install this is where it can get tricky, the Allen wrench they provide is a tad too long, so what I did was took some gorilla glue and put some on the bolt head, so I could thread the wheelers on like the stock one. Worked like a charm. I do believe that you could prob do it without jacking the vehicle or removing the wheels, but I was installing new sway bar end links so I needed to have my wheels off anyway for more room to work.
