Got my car up on Jack stands because I'm about to do the 4.57 gear swap. Before I even got started, I notice these minor cracks around the housing that I'm not sure of. Just ignore the oil stains and drippies b/c i didn't clean up after changing out the fluid. SO....


Are these cracks a sign of premature diff failuer, or are these just casting marks???
Is this something that can be covered under warrenty, cuz I'm s/c'ed ? Even so, I hear so many stories that the diff is crap on the 'S'

What do you guys think??? Please help


Thanks,

Philip D.

Casting marks.

Sideways

Those are casting marks as stated. I removed some of them when I polished my pumpkin.

Don't worry Swtazn, they all look like that. Definitly Casting marks.

Thanks everyone for your input. Now i have a clear conscience to start on the gear swap

Stratocaster

Also that is just the cover, it just holds the oil in and the dirt out.
