I have a 2000 4WD Blazer, 4.3 L on which I need to replace the rear wheel bearings and seals. I need the axle code, which is supposed to be stamped on the right rear axle tube. The tube is very, very rusty, and despite my attempts to clean this up and read the code, I am unable to find anything that looks like numbers or letters. Is there another way to determine the code? I need to know whether it is a "C" or a "K" so that I get the correct parts. Thanks a lot.
