Re: Please help
Live axle has the center housing extending out to the hubs, much like most rear wheel drives. When you hit a bump on on tire, the entire shaft rear end will move. On an independent, the center housing is locked in place and u-joints or CV joints attach to the shafts so that only the side that hits the bump is affected. An IRS will keep more rubber to the pavement allowing for better traction and handling.
