Hello all. Had a squeak from the rear on my 03 LTZ and noticed the emergency brake shoe linings are gone as well as the backing plates. I really am nervous about doing this job. I ordered new shoes, plates and seals. Question is what are the chances of the spider gears falling out cause I don't want to damage the rear differential especially when I start tapping the new seals in. Was thinking of slowly pulling out the pin, slide the axle shaft half way out then temporarily pushing the pin back in before removing the axle all the way out. Will that keep the gears from falling out? Doing one side at a time just to be on the safe side. My only vehicle so can't make a tragic mistake.
