Cracks in Front Differential Housing? - 6/12/2006 5:38:32 PM

I have a 1993 3/4 ton 4x4 Suburban. While changing the oil this weekend, I noticed what look like stress cracks on the front differential housing (which appears to be made of aluminum). One may be a casting mark, but the other definitely looks like a crack. I have rarely run this truck in 4wd. Has anyone else noticed this abnormality? Thanks.
