I wheeled my 90 with IFS for almost 4 years until the front was so bent up it wouldn't work anymore. Then I went with the solid front axle because it would have taken just as much work to create all new mounts for the front IFS diff. They were pretty much pretzeled by the time I dumped the IFS. There were very few places I couldn't go that others I wheeled with went. 3 wheeling looks great for the camera, #1 advantage of IFS
