Working on the truck and have it apart. The replacement part that I bought was GM PN 89059059. I have a 2WD truck which doesn't look like it has a spindle nut.

Here are pic's of the existing and new parts. Do I have the wrong part?

The new one is for a 4wd truck.
I think the part number is 15753476.

Yes, you got the wrong part. The 4wd part uses the axle/nut to hold the bearing together. The 2wd has a spanner nut on the backside to hold it together...

Gentlemen, much thanks. I always ask the same question at least two ways to make sure it's right, but the AUTOPARTS boys got me on this one. Putting it back together...

Are there anyother parts that should be replaced while I'm in there? O-ring seals, etc.???


Thanks again. Brian.

should be it,thats a sealed bearing

Gent's,

The story unfolds, the correct number is GM PN 89059056 or ACDelco PN FW163.

It isn't available until Monday so I'm down.

I could use one more bit of help. I need the PN for the seal/O-Ring (Part #7 in the attached image). Could one of you guys help?

Thanks. Brian.
