Just to be clear, if possible I would try to remove the springs without removing the axle. Its just more work and I remember doing these without removing the axle. But if you must remove the axle, heres what you will need to do:
REAR AXLE 9 1/4
(1)Place transmission in neutral.
(2)Raise and support the vehicle.
(3)Remove wheel and tire assembly.
(4)Remove brake caliper. adapter and rotor (Fig. 19).
(5)Remove differential housing cover and drain lubricant.
(6)Rotate differential case so pinion mate shaft lock screw is accessible. Remove lock screw and pinion mare shaft from differential case (Fig. 20).
(7)Push axle shaft inward and remove axle shaft C-lock from the axle shaft (Fig. 21).
(8)Remove axle shaft (Fig. 22) carefully to prevent damage to the shaft bearing and seal in the axle tube
(1)Lubricate bearing bore and seal lip with gear lubricant.
(2)Install axle shaft and engage into side gear splines.
NOTE : Use care to prevent shaft splines from dam- aging axle shaft seal.
(3)Insert C-lock in end of axle shaft then push axle shaft outward to seat C-lock in side gear.
(4)Insert pinion shaft into differential case and through thrust washers and differential pinions.
(5)Align hole in shaft with hole in the differential case and install lock screw with Lottite5 on the threads. Tighten lock strew to 11 N.m (8ft. lbs.).
(6)Install differential rover and fill with gear lubricant to the bottom of the fill plug hole.
(7)Install brake rotor, caliper adapter and caliper.
(8)Install wheel and tire.
