F150 rearend issue

I know this isn't MN12 releated, but someone may be able to help.

Have a friend w/ a 97 F150 4.6L. After having Darrin build me a nice new trans. for it I go to start filling her up w/ fluid and after it finally starts to try and grab gears, I hear a familiar horrific noise from something in the drivetrain. Knowing that the trans. is new I turn my attention to the rearend.

After pulling the cover and taking a look, I see a few things that are out of place. Keep in mind that I do not know all the names for these parts so I may not describe it all perfectly..

1. A rather large roller bearing that resides in the outer edge of the case has been totally obliterated and all the rollers are laying in the bottom of the pumpkin. What looks like was part of the metal sleeve that holds these rollers in place was chewed up and twisted out as well.

2. between the inner edge of the case and what looks to be a large cap (has 2 bolts, looks like it holds the gearset in, kinda looks like a main bearing cap in a motor) I can see that there is about a 2" section of hardened steel missing. I found these pieces in the pumpkin w/ the roller bearings.

3. It appears as though that entire side is just kinda flopping around in the carrier. With that bearing gone, I guess it would. I also noticed misc. knicks on the pinion gear.

Basically this thing is a mess. I'm not even sure if it can be rebuilt (don't know if the pumpkin is damaged or not). If anyone can provide some imput here it would be much appreciated.

These are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test.

Sounds like it spit out a carrier bearing. I'm sure the case can be salvaged,but the ring and pinion and all internals may be destroyed.

Thanks Alan. I guess I'll have it towed somewhere and have the rearend rebuilt.

I would go to a junk yard and see whats avaliable first. Those trucks are everywere and truck rear ends are not that hard to replace. May be chaeper that way.

We've discussed the junkyard idea, and while I know I could do it, at this point he just wants to get it back on the road. It took us a while just to get the trans. in due to time constraints on both our ends and replacing the rear would just be another drawn out process. He wants to pay me (in the form of his 99 Grand Prix GT) and just get the truck done and I need the GP. My 84 Vic has developed a nice frame flex on the entire front end lately and I don't think she can take much more. After 22 years of daily driving and 372,xxx miles it's time to put her down and get the new frame under her that I have in the garage...

Now the only issue is finding a reputable shop that can replace the rear and get it right the first time, since I've heard these rears can be notorious for whine and whatnot, and keeping the cost tolerable.

If anyone has input as to a good place to take it near the St. Charles, MO area I'm all ears.

I'll talk to a couple shops in the area and see what kind of prices I get. I just might take you up on the offer.
