I used a 2nd jack to push the box wrench "up" while the backhold wrench was in contact with the ground to loosen the bolts....took alittle time but it worked.
I also cut the old arm in half with a sawzall to take the pressure off the bolts to remove them easily.
I had to sawzall the right front bolt off...also took time but finally cut thru.
I used a come-a-long from the shock bracket to my hitchs chain eyelet to position the axle for inserting the bolts.
I still gotta get a new replacement for the bolt I cut.
