Hello,

I've searched here on the forum and also on the interwebs... But there doesn't seem to be any info on how to decode our truck rear axle casting numbers... And also what the casting numbers tell us. Forgive me if the info is here, but again I searched and couldn't find --

Anyway, the casting numbers on my rear axle are as follows --

NF3896888 GM 59

Thanks for the help!!
