the rear
raise and support the rear of the truck safely
best by the spring itself
the put a jack under the rear axle
remove the bolts from the u bolts and remove u bolts
now sometimes I have heard the rear end is tough to separate from the springs, it does come apart,
DO NOT REMOVE THE SMALL BOLT GOING THRU THE SPRING PACK
then install the blocks , locating them with the pins, install new u bolts, tighten , leter down.
recheckthe ubolts after the first 100 miles for tightness.
oh and the last pic? you guys thought I was a guy?
