Re: Speed related whine
Just a possible check is first check your power steering fluid. When it runs low it can make the front end do many weird things. Also check if the front rotors are very warm. If I am correct to understand you have a 96 not a 2002. If so, they have dual piston calipers, which sometimes will hang one piston and apply the brake pad at an angle which will make them drag and wobble the calipers and rotors and give you a rough feel through the wheel. Hope this helps.

Sounds like it could be the wheel bearing. Jack up the car, and see if the tire feels loose when pushing in and out at the top and bottom of the tire. That;s the most obvious way to check. But many times, the bearing is tight, but still bad.
The pattern you describe is consistent with an alternator going bad. Maybe the fields are already rubbing together. Test it this way: Start the car and leave on idle, when the whine is worse, then start using up electricity, by increasing the demand. Turn on AC, then lights, then full blower and then high beams. If there is a change in the whine, then either alternator or voltage regulator is the culprit. When a compressor pulley bearing is bad, noise shifts just by turning AC on and off.
The sad news is that the new motor will probably whine also. The best way to fix the whine is to use the switch to select different speeds. It is is whining at one speed, it usually will not whine at a different speed, at least for a while, or until you turn a corner.
Speed issues are usually related to the switches resistor pack which is easy to replace.
Well you can remove the sensor in the diff and make sure that looks ok they g obad quiet often also woulnd not hurt too remove the rear diff cover and inspect the rear end if it is whining and you dont see anything wrong i would refill it with lucas oil/grease and start praying check the pinion too and see if it has any play in it
