brakes, bearings, or differential broke in front

I do not see anything about the tires in your description of the problem. Might look into those things because they are what cause "speed related" issues when you drive.

The problem may be related to technical service bulletin TSB 03-001-07 which involves replacing the front axle actuator disconnect and a software update. You should be able to Google the TSB and look at the build date listed in the bulletin to determine if it applies to your vehicle.
