With the axle still supported by a jack, remove the U-bolts. To remove the front springs, remove the rear leaf bolt nut but don’t pull the bolt out yet. Move to the front of the spring and remove the front bolt. To access the front leaf bolt you’ll have to also remove the A/C brackets. While holding the weighty front part of the leaf in your arm, slide the rear leaf bolt out and remove the springs. To install the new leaf springs, have a buddy hold the leaf while you insert the rear bolt, and then slide the front bolt into place.
