Brew....When I dId lil Red's rear axle, I took one from on 02 SCrew with 355 LS and disc brakes. The only difference was the right side e-brake cable. I have a SB/RC, so it was too long from the SCrew. The 14 mm studs were no problem, as when I did the front brakes to the upgrade, I swapped to 14mm front hubs. That gave me everything as a match and I like the overall swap.
A while back I was reading that the 99+ got beefier bearings in it.... and maybe bigger axle shafts. Might have been AK that I was reading that from, lol.
FOUND IT!! I had it bookmarked:
The 9.75 axle has had a few changes in its relatively short life, including larger axle bearings and shafts in '99 (from a 1.620-inch inner diameter to 1.705 inches), a larger outer pinion bearing (increased from 1.31 x 2.68 inches to 1.31 x 3.00 inches), and the pinion was altered for a longer crush sleeve.
My take on that. - Gen 11 get back joke. There was a lot of crap happening at the time among auto makers. Out of the bunch, Ford was sitting pretty, far from bankruptcy or seeking government assistance. Ford won the class action suit pertaining to gen 10 plug blow outs. But it seemed Ford remained red faced, came up with a kamikaze 3V for 04. Designed two piece plugs to be very disagreeable to remove (in one piece anyway) and spec'ed injectors with bladder problems, let alone the phaser brain fart. Seeing the hardship this cost for a family up close, with Ford absolutely refusing to cover their mistake which meant extending the recall 6 more months, - just blew me away.
Can't forget the under pressured oil pumps. They were expecting an awful lot to be done with the 40psi pump.
Whitey......99 and 00 had both sets of axles. The 915-919 series still had the small axles and bearings.. The 921 and up had the heavy duty axles and bearings. Both were available until mid 2001 models. If you get an axle, if the codes is the lower 9..'x then it will have the small set up. The tubes on the axles were basically 8.8 tubes until they went with the HD 1.7 axles.

Looks like sticking to 02/03 assemblies is the way to go. Earliest would be 01 ? Definitely want the larger axle and bearings. Yea, I'll go 14mm in front like you have as well....with a bearing change. This way I can do away with rotor bushings which keep the 14mm Expy rotors dead center. Have to say that little invention has worked flawlessly with the 12mm set up, no shifting or movement. Bushing are just another thing loose when working on the front brakes...most definitely non-OEM lol.
Did you ever go for the larger booster ? We talked about that once, what ever happened with that ? I think it's a good idea. Ford went larger for a reason, anything from the manufacturer to better the brakes on these things are far from overkill imo. Yea curious if you went through that and noticed any difference.
Thanks for the info as always AK.

Damn, yea, read through it ..twice! A truetrac would be nice, so would lockers. Sure would be nice to eliminate the clutches all together. I bet it's close to 2G setting the 9.75 up...if you go with the Yukon Alloy Axles. But man, comparing the 9.75 to a dana 60 ? Never new that was possible. Was under the impression we wouldn't see that kind of strength again, not from the auto manufacturers anyway. That's all too obvious, but the 9.75 is lot closer than I thought. Hell, mine along with many others had problems with them well below 100K. Ford came up with a TSB to quiet them down (howling issue). That TSB was part lengthy and pricey. No one really went for it because of the expense and most were past warranty. As it turned out, the 9.75's could last another couple100k howling away lol. That must be what Ford addressed later on in these trucks. Anyway yea, going with the article you posted, Dana 60's, the old Ford 9" set-ups...those were the days right. Guess I'm surprised that the big boys actually have good things to say about the Fords Sterlings, well the 9.75's anyway...side by side, up against a 60 lol. A compliment for sure. Huh.

It was so messed up, how could they mess up shi up THAT bad? The first 3V's meant for the 150's , #1 truck in the US. Well, that engine was a weak proto type. It should of blew up in their faces way before final production. We were guinea powned badly. I lost some respect for them there.
Thanks for the info White!

Reason: Moved exhaust pic, off topic.
This guy had been in front of me for about a half mile. Shortest route back to the hotel was to turn left, but I took the slightly longer way so I could see (and breathe).

Hey White, on a 5.8 with gt40 heads; you need a first gen lightning lower intake manifold, and what upper? Will any gt40 upper from a 5.0 work and flow fine?

Just thought it was funny/ironic to see that today
Brew......here is an axle id chart that will give you the numbers and ratios. Ours starts at page 15. It should help you when looking for information on them.
I haven't done the booster on Red yet. I'll probably just wait till next spring. I lost those 3 weeks starting in September, so that slowed down my things I wanted to do. Oh well, next year isn't that far off. LOL
