Advice

Getting everything together to re-do the front end of my 1997 Jimmy 4x4.There are a couple of things I could use some advice on.I will need to take the pressure off of the torsion bar. Can someone give me the right way to do this? Next the control arm bushings how hard are they to come out?Should I take it to a shop to press them or do them myself? I dont have any tools to change them myself.How many bushings are in each arm?

Thanks:banghead:
