who's long arms?
are they a radius arm style long arm - I.E. the Upper control arm attaches to the LCA and the LCA attaches to the frame - you only ahve 2 contact points with the frame (excluding the trackbar)
if so - put 2 bushings back in, your suspension is binding, not the coils...
look into where your suspension/steering/trackbar/shocks/brake lines bind by putting the jeep on jackstands and removing the srpings, then manualy moving the axle up and down, and using a jack to move one side up, and you jump on the other side....
you will find your bind... and i garantee it isnt your coils - once coils reach max droop, they fall out and the axle keeps drooping....
