I know the feeling about getting out for some windshield time, quality windshield time, where you have nowhere to go, nothing to do, and plenty of scenery to see, while the motor purrs, and the tires sing. Fore sure, my truck is my therapy couch. Troubles & cares just go out the open window.

This be the bearing that you need---> http://www.summitracing.com/parts/bca-rub1580ebfr
Pricey.
I get mine from a local bearing supplier for a bit less.

Hmmm. ....ebfr. I think the number on the bearings I currently have end in, ebFUBAR.
I'll have to check into those you mentioned, to find the dimensions on them BEFORE I buy anything (else).

Hey, if you can't laugh at your own ignorance from time to time then you're just not a very good sport.
When you're taking parts from one vehicle and adapting/installing them in another --especially if there's little or no information on the net about what you're trying to do, it's just an inherent risk you take of it working or not working. Simple as that. Its all a part of the essence that makes a gear head a gear head.
Same story with the '79 Bronco rear sway bar I installed. I generally try and thoroughly research things BEFORE I just jump into them. Sometimes things get over looked and sometimes you just don't know what you don't know until you start to put something on. In the case of the rear bar, I couldn't find any information/photos of its use in a Bumpside truck.
I don't know (yet) if it's going to work but, me being able to at least get it fitted up is 50% of the task. If it does work, that'll complete the other 50% that my gamble in putting it on actually worked.
While a failure isn't fun and is a (temporary) setback, I did learn some valuable information out of this and, anyone reading this will have learned something too. (Just at MY expense).
It wasn't a total loss though.

Hola amigos,
Just wondering, since Ultra & Insta are posting on this forum, have you guys, or any others out there, heard of anybody installing one of those fold-out-down steps, on a 'Bump' tailgate? I'm thinking that my highboy could really use one, and if it has already been invented, why reinvent the wheel? Its not that I need another project, when I am still mid stream on the flatbed/stock bed restore. Sometimes I just think over the horizon, further than I can see.

I put my caliper on the O.D. of the axle bearing journal and then I put the caliper on the I.D. of the bearing and the caliper said, "The I.D. of the bearing is exactly too damn big."
The 31-spline axle journal is about 1-17/32" (1.5313"). The I.D. of the bearing is about 1-5/8" (1.6250").
--I say, "ABOUT" because the battery in my calipers seems to have given up the ghost. I just had to put the caliper on the items and then measure the distance of the caliper points on a tape measure.
There seems to be forces in the universe conspiring against me at this particular moment in my existence, in keeping me from reaching completion of the tasks at hand on my truck. --I may have lost this particular battle but, the war ain't over yet.

17/32" (.5313") is one 'tick' larger than a half inch (.500") and is larger than 3/8" (.3750").
The DOTZ bearing I.D. is roughly 1-5/8" in diameter (~1.6250") and would be ~1/4" (.250") larger than the 1-3/8" (1.375") diameter listed.
I'm not certain if there's a misprint from your information source or, if it was just simply an accidental case of fat-fingering the keyboard? --it happens.
The I.D. of these DOTZ bearings comes out at around 1-5/8" so, it's definitely greater than either 1-3/8" or 1-17/32" for sure.

Earlier I was looking in JAN 1975 final issue section 40.3,pages 1 & 2. This is where the axle tag numbers tell me which style axle bearings are used. I took your part number D0TZ1225A,checked that it did indeed fit 9 3/8" R/G with 4 pinion Traction Loks and tags WFF-A,-B,-C. These tags show axle bearing style "ER" on page two. On page one style ER is listed as ER....D0TZ1225A....1 3/8" I.D....3 9/64" O.D.
Hey Bill, if you're out there can you post these pages for me please?

Ahh. You are correct O' wise one. This time I looked in JAN 1975 final issue section 12,page 17 (under 1225) and it lists the I.D. of D0TZ1225A at 1 5/8" and including C1VY1180A collar.

Now, I didn't physically pull these 31-spline axles myself. One came from Hope, Arkansas and the other came from somewhere in Arizona.
If the 9-3/8" rear ends came out in the '68-'72 model F100s (and they did), the evidence, based on the axle bearing dimensions and the change in part numbers, would seem to suggest that there was also a change in the axles themselves between the 1969 and 1970 model years. --axle journal diameters of the 9-3/8" axles increased in size between 1969 to 1970 (?).
The DOTZ bearing is obviously way too large for the 31-spline axles I have, yet, the axle bearing I pulled off one of the 31-spline axles is larger than the journal of the 28-spline axles I just pulled out of my '69 F100.
The bearing journal of my stock 28-spline axle is right at 1.500". The bearing journal on my 31-spline axle(s) is 1-17/32" or, 1/32" larger in this area than on my 28-spline axles.
This is the only logical explanation I can think of. Until hard evidence can be presented of what the facts really are, I suppose it may just remain one of the great mysteries of the universe.
