I started out doing a rear main seal and when I dropped the rear cap,bearings didn't look so good.
Appear to be water damaged.
60k on motor.
Anyway,I took all of the mains out and to my suprise,numbers 1 and 3 are .001 and 2 and 4 are std.
Ever run across this.
I know why this was done just seeing if anyone else has seen this.
By the way,they are stamped GM on them.
I will also be doing rod bearings while I'm under there.
