It's drIving me insane. It's at the ford dealer now. Called this am told the guy I ran a shop, told him the situation, gave him the outrageous quote, he laughed said he would give me all my parts at shop cost, and gave me a discount on the labor-10 bucks an hour, and said he has seen a ton of these rear ends come through and he's only done gears once. It's usually bearings. It's a 4 or 6 hour job depending on what's worn. Makes me feel a bit better.
That sounds more like it! The shop that did mine said the same thing after 21 years in business! Fwiw I paid 1,065.59$ to have all new bearings and seals installed, my carrier bearings were ready to explode! I got pics of the old stuff I'll post later

I do believe I have the same gear whine youre referring to. Let me also add that much of that whine came from my center support bearing for the drive shaft.
My 2002 f350 has 195k miles (brand new tranny) and the whine, starting right at 30mph and above, was super crazy ridiculously loud.
I changed the center support bearing today (rubber support was all torn up) and the noise is much reduced, but its still present.
I wish someone would detail how to preload the yoke. This might solve my problem.

Actually it's in this thread, let me know if you have more questions, I rebuilt them as a job many years ago along with sticks and automatics.

So this crush washer thingy which I need to preload is in the rear axle? I need to take the wheel and brakes off to re-tension this? BTW, I noticed a stain on the read differential cover...you think it could be related to the whine? The diff oil has been changed regularly. 196k miles on it. Auto tranny is brand new.

You're very kind. Thanks. Well, now that the center support is new, (BTW, no way I could get 300 foot pounds on the drive shaft nut....lucky if I got 200), I hear the gear whine, gear groan starting from about 20mph...crescendo at 40mph. Sounds like it coming from behind me.

It sounds like something is worn in there. The crush sleeve is in between the 2 pinion bearings and all it does is keep the nut tight. If you need a new one to get at least 100 foot pounds of torque you might be able to fish it out from behind the yoke and front bearing (I haven't worked on these), but I am doubting if it will help. When you turn the yoke back and forth it should be snug with no rough feel and not loose. It sounds like you have a bearing going out but check the feel of the yoke and if you can get 100 pounds of torque on it without making the bearing tight you will be OK but you would need seizing compound to help hold the nut. The crush sleeve is like a sheet metal tube about 3" with a little bulge in it that expands at the bulge when you tighten the nut and the 2 bearings get tighter in the bearing cones to the point where they just have a little drag on them. The sleeve has a little spring to it and the bearings wear out which will usually let you put a little more squeeze on it but you must be careful to go too far (too tight) or you will be back to needing a new sleeve. The main thing is to just jack up one wheel, remove shaft, and wiggle the yoke to see how it feels for starters.
Thanks for your patience and assistance.

aha I see. ok so this is where I need some instruction...how to access the yoke (whatever that is! hahaha!). I need to check Chiltons and alldata etc. This is my first rear wheel drive vehicle...and first truck...so I am learning as I go. I jumped into the deep end of the pool on my first swim, so to speak, cause this 2002 has 196,000 miles on it. I put in a new tranny myself, etc etc, but some things are all new to me.
Thanks for your patience and assistance.

I need to look up what the IT youre referring to is...ALLDATA says I have one of 2 rear diffs, Dana s135, or Dana 80. I dont know that offhand...
I dont see YOKE mentioned once in the 2 diagrams. Does this part go by another name?

Arent I supposed to check if it has slop in it which might be causing the gear whine/groan above 25mph which is making me batty?

Check it while on, see above posts. Wiggle it , push in and out, up and down, feel for roughness, tightness.
