Check your power steering fluid level. You might also have some air trapped in the rack.

Fluid may be low also wait for the car to warm up and see if it still makes a noise then. Sometimes on my old pick up, steering will whine on a cold start, fine when warmed up.

If you think its still coming from the rear just put another friction moddifier in. Sometimes it takes 2 bottles to fix the problem..

Friction modifier really has nothing to do with rear axle whine. It's only there to lube the clutch packs to keep them from chattering.

To bleed air from your p/s.

1. Idle the engine to bring the hydraulic steering fluid to operating temperature (60-80 C degrees, 140-170 F degrees).
2. Add fluid to bring system up to proper specifications.
3. With engine idling, cycle the steering wheel from side to side 10-15 times. Do not turn too quickly or hold in the lock position for more than 10 seconds.
4. Refill the power steering pump to proper specifications.
5. Check hydraulic fluid for color—if tan, light red, foamy or cloudy, air is still in the system. Repeat steps 3, 4 and 5 (for cars with rack and pinion, it may be helpful to let car sit for 30 minutes before repeating steps 3, 4 and 5).
If all the air is not removed from the system, an abnormal intermittent whine, moan or continuous growing noise may be heard form the power steering system. In some cases, a "shudder" may be felt in the steering wheel while driving the vehicle. If possibility of an air leak exists, check the entire system for leaks, repair as necessary and bleed the system.

On my other Fords I jack up the front end and place on jack stands for turning lock to lock. Seemed to work well with the old vane type (Thompson style) pumps. Even used this method on my Bronco when I replaced the original vane pump with a new Saginaw pump.
