My  91 XJS is grinding noticably after 45 minutes or so of driving from the right front wheel area.  I'm thinking wheel bearings (both inner and outer) need to be replaced. I am not noticing excessive heat at the wheel or rotor. Is my diagnosis sound?  I have not done this for a while,  last time was a old F-150 truck.  Is the procedure similar?  Should I expect surprises?  Any insight would be helpful.

Thanks,
