97 Grand Prix GTP Wheel Hub Bolt Sizes

[duke_winchester]

I have to replace one of the front wheel bearing/hub assemblies on my 97 Pontiac Grand Prix GTP. I wanted to get information on the 3 bolts that go into the back side of the hub assembly and hold it in, as I want to replace these during the procedure. Does anyone know the sizes (thread distance/size, bolt length, etc.) of these 3 bolts and where I can get them so that I can do so before I begin the process? Thanks

I honestly don't see the point in replacing them unless they are rusted beyond belief. I had no issues getting mine out and my car was over 160k miles at the time (actually hit 172k today)

Only thing I did was used a drop of loctite on each bolt when I reinstalled.

I already replaced the hubs once before, and my car is pretty old (205,000 miles). I just wanted to replace them for good measure if I could find out the sizes.
