Hey guys, what size is the center axle/hub nut? Also, I have an electric impact wrench thats about 230 ft. lbs, would that be enough to crack loose the 3 hub bolts?

 

I don't remember exactly nut I'm wanting to say 30mm or 32mm. If you call the local auto parts store they might be able to tell you. Also make sure you torque that to spec or it will wear the wheel bearing quicker.

3 hub nuts the impact should do it depending how rusty they are etc. I suggest spraying with pb blaster and letting it soak a few times before attempting to get them off.

 

The hub bolt should be a 36.

Which rims do you have on your car?

If it's these ugly ones, you can just pop the cover from the lug nuts and you have full access to the axle nut. Then you can ask an auto store if you can just grab a few sizes and go out and see what fits, then buy what does.

I don't remember mine being that big.... it's possible though. I have a 30,32,34,36 so I don't remember for sure what size it is. I may be thinking about my old cavalier being the 30 or 32 instead of the monte...

 

I did a little search and chibi is correct the factory axle nut is a 36 but if the axle was replaced before it could be a 34.

Torque spec for that nut is 118ft lb

 

I got Pontiac wheels on mine.. was on there when I bought the car. They are the right size tire, etc, and do look better then factory MC wheels, but I like all original... oh well. I'll shoot for the 36.
