03 Explorer rear whine?

[szyd]

03 Explorer XLT 4.0 auto 156,000.00
While driving the rear has a whine. The whine is more prevalent when foot is on the throttle. Thinking Wheel bearing but no felt or visible play. Also when warm their is a bang when going from any gear to reverse. It seems to take a second when shifting into reverse for trans or rear end to catch up than Bang. Which has me thinking rear end. Any body have similar problems they have addressed?

It also seems to studder when going in to OD which i think is unrelated to the above problem. Any help or thoughts on this would be grate.

Got this a great price so throwing a little coin it's way won't hurt to much.

Sounds to me you may have a transmission issue more than a rear end problem. From my experiences with similar issues you mentioned about the popping into reverse, it may be the torque converter. The whine you are hearing could be a lack of transmission fluid being pumped through the transmission. I am no tranny expert by no means, just throwing out a suggestion.

Thanks I may have to have a shop take a look. Makes sense.

Rear diff. is most likely the issue. We replaced tons of them on the 03 Explorers.

You ever get it figured out?

sounds like pinion bearings are out of it. and the second issue sounds like it needs a new solenoid pack, did plenty of them when i worked at ford for the same symptoms you have.
