Bearing hub assy R/R

[rufousray]

I'm helping my son-in-law / daughter with their 2000 cavalier. The car makes a humming noise above 45 MPH. I suspect a front wheel bearing. We tried to remove the old assy and were stopped at the three bolts securing the hub to the steering knuckle. They appear to be Torx bolts. T50 is too small, T55 is too big. Is there an in-between size? If so, where do I find it? Thanks for any help.

It has to be one size or another.Order new bolts from the dealer and size them up.

I thought that it is a 3/8 allen wrench size??
