1998 Chevy Blazer How to remove the c-lock

Drive Train Axles Bearings problem
1998 Chevy Blazer 6 cyl Four Wheel Drive Automatic

Hi Everyone, I'm trying to replace the rear right axle seal from a 1998 Chevy Blazer. But i'm having a hard time getting the C-Lock clip from the end of the axle shaft. So far the instructions I have seen on a google search is the following: push shaft inward & remove c-lock. But no mention of a special tool is mentioned. Am I missing something?

You have the brakes all apart so the axle is clear? Remove the rear cover on the differential housing, Now toss some kitty litter in the big oil puddle you just created!
Now for the fun part. There is a locking bolt that goes through the differential and holds the axles out. You need to rotate the differential carrier to a spot where you can remove that bolt. WARNING, it will be TIGHT. Remove the bolt and bandage the cuts from the sharp edges you hit when the bolt finally broke free. Now you should be able to give the axle a good whack with a chunk of wood and a heavy hammer and move it in far enough to get the retainer out. Check that retainer VERY close for wear. I usually just replace them (it's the ONLY thing holding the axle in) Now you can pull the axle out and change the seal and check the axle for bearing wear and the bearing itself for damage. ANY vertical play in the axle means you have some wear. Install the new parts and use a protector over the splines when you install the axle, you don't want to damage the new seal. While you have it apart you may as well change the other side, unless it was just changed. Also look at the cover real close for thin spots caused by rust. Clean out the old oil and look over the gears as well. If the pinion seal is leaking now would be a good time to change it as well. Reassemble the cover with a new gasket and refill with a good synthetic oil. Enjoy.
