Question about Chevrolet C1500
Remove the rear cover, drain the oil out, remove the retainer bolt on the differential (be careful not to drop it into the spyder gear sets) you will see there a "C" clips which retain the axle shafts into their splined fittings in the differential. Remove the "C" clips by pulling them out with needle nose pliers, magnetic if possible. The axle shafts then slide out, inspect the seals (all three lips) at the end of the axle tube when the shaft is out, I would probably replace them (both sides) as they are inexpensive and easy to install. Also inspect the axle shaft where the seal resides during installation for grooves. The idea here is a visual inspection to insure the axle fluid in the third member and tubes does not get onto the brakes/brake system....safety first.
Of course remove the necessary hardware at the end of the axle shafts (where the wheels mount) I cannot see what you have.
I hope this helps. Are the gear ratios the same from axle to axle? If not you will have an N/V issue which will cause your speedometer to read incorrectly. The glove box has a spill sheet that tells all the RPO's for the options. The axles start with G, (GT3, GT4 etc.) You will have a 3.23:1 or a 3.42:1 or a 3.73:1 or a 4.11:1 and so on There is a correlation between the numbers at the end of the GT and the ratio.
Another way to see if you have the same ratio is to rotate axle once and see how many times the pinion turns and you will be close to that ratio. Example if the pinion turns about three and a half times to one rotation of the axle, you probably have a 3.42:1 and so on. Mark the axle hub and pinion with ink before this calculation. Also, you may or may not have limited slip, and your carrier in the third member will be different and the dissassembly will be different although the axles are still held in by the clips...Limited slip or "posi traction" is designated on the glove box sticker as G80.
I hope this helps.
