How do you get a Suspension to hook, when the track surface is marginal at best

Do you have trouble getting the axles out,if so its pretty bent otherwise jig it and have them brace it while there or move to a dana or something,thats where i'm at but that 8 3/4 still going 10.70's @ 3450lbs and i'm not sure if you said but some aftermarket axles would be in order as well but i understand about a budget only so much to go around
