10 bolt sf bearings

[gmcman7202]

ok i just tore apart the rear end on my 1999 tahoe with 100k on it. the oil seal was spewing. i decided to replace the bearings, oil seal, and all the brake components. when i got the bearing out, after a huge ordeal on the first one, and i do have a shide hammer. i saw the top part of the race, that comes in contact with the housing was pitted and from the looks of it it was do to heat. the bearings look fine. there was fluid in the whole deal. was jsut changed within the last year. i am thinking the fluid leaked far enough where it would caus it to become pitted like that. as i am not sure as how long it has been leaking, as i am not the dd, just know the breaks now suck.

i am asking if the pitting on the race is normal. does this happen often? how else could it of been caused. thanks guys

I've never seen a race pitted on the outside. On SF axles, it's usually the polished part of the axle shaft that starts to pit, as it is the inner race.

Wait, the housing, where the axle bearing in pressed into is pitted?!?!?! That doesnt make sense. Do you mean the axle where the bearing rides is pitted?

gm made a ff 10 bolt?

does there need to be a distinction?

ok guys its on the outside of the race, not where the bearings ride, so its also on the housing where the race is pressed into. but only on the upper part of the housing.
