First time attempting this - car is sitting on jackstands, removed my rear axle (Ford 9 inch) to rebuild third member. As an exercise, I reinstalled the empty axle housing and hooked up all the suspension (coil overs, triangulated Pete& Jakes ladder bars, panhard rod). I have only floor jack and jack stands and wanted to see if I felt confident lying on my back I could install third member with the axle housing and suspension in place. Didn't like it. I removed axle housing and installed third member into it out of the car. Been trying to get the axle assembly back into the car but can't get the ladder bars to bolt up. Had no trouble installing the empty housing and suspension but seems the weight of the third member is causing me problems. I didn't change any of the suspension adjustments. I can attach the coilovers and panhard rod but can't get the ladder bars done. Appreciate any advice.
