2003 Alero wheel bearing grinding?

[moss]

I replace with a Moog wheel hub. I reused the old axle nut because I thought the wheel hub would come with a new nut so I hadn't bought a new one. I torqued the old one to 175 ft lbs. Do I need to buy a new/updated axle nut?

As I posted earlier for that model GM has an updated hub nut to go along with the revised tq spec that suppose to have increased retention ability. Technically you aren't suppose to reuse hub nuts. It will probably be OK. I would get the new hub nut. Actually I'd get two and put the other on the other side at the new tq spec so maybe it'll last longer.
