    The shaft number you need is a 917059-0912 It is not available thru anyone that I have found. So being made is not that big of a deal. if its not bent to heck they can weld new yokes on each end. I have a New in the box Driveshaft for the Transfer case to the No 3 axle but not the 3 to 4.

    The yoke you need for the input on the # 4 axle is Spicer part number 5-4-5511X found thru ebay for about $200 or so or your local parts place can order it directly from spicer. The Crossville, TN warehouse is showing 133 of them in stock. This would be the yoke that bolts to the axle that your u joint would go into for the input side of the #4 axle. it is # 43 in the pictured TM

    It was very interesting to read all of the interpretations of which drive axle does what, the whole 8x8, 4x4, and the best is that only the rear axle drives in normal operation. I'm happy that the yoke and shaft problem were solved. I do enjoy this site. Thanks guys.

    Simp5782 ,where I can find a manual with this pictures that you post on #11 ? it will prevent me to ask this stupid Questions
    Is yoke coming out from axle 3 to the shaft to axle 4 ,is the same part nr that you give me for yoke on axle 4 ?
    I been used torch to cut ujoint on this yoke, looks ok ,but Im worry that is maybe overheated and have some internal damage ,and maybe its good idea to replace this yoke too.
    Behind this yokes are probably oil seals ,do you now parts nr for them ?
    Im really appreciate it

    Now, according to TM 9-2320-279-24P1, Fig. 168, Item #4, those particular U-joints are of the smaller 1610-series (5-279X).
    It seems that only the M984 and M984A1 variants have the stronger U-joints there.

    Then in post #11 you gave him the Spicer equivalent part number for that #4 input yoke: 5-4-5511X, plus the drive shaft part number (= NSN 2520-01-254-1278 ), which are both correct for the M983 (per TM).

    So maybe it was obvious, but for the sake of completeness, and since I can't seem to find where you posted it: that DS, as well as the yoke - takes the 5-279X U-joints, not the 5-280X.

    Figure 182 part # 13. That is the seal for the OUTPUT of the 3rd axle to the 4th axle. Part number 113514. The input seal for the #3 axle for the transfer case side is #113515

    Those are both Eaton Fuller numbers Both are found on ebay for cheap.

    My mistake. However it uses 1710s (280X for the Transmission to transfer case and Transfer case to power axles being # 2 and # 3 axles use that joint. They use the smaller 1610s - 279 joints for between the axles like the 5 tons do. Contrary to our conversation you and I had over dinner about the 4 inch driveshafts on the HEMTTs. The Transmission to Transfer used a 4 inch shaft. The Transfer to # 3 axle shaft is a 3.75 and uses 280x joints. However the shafts between the axles are 3.5" diameter using 1610s. Some idiot at oshkosh thought to make things not all the same. i don't get their reasoning

    You need to pay more attention to the UOC listings... (UOC stands for "Usable-On-Code", with the different codes explained in the introduction, page 6 of the parts book TM 9-2320-279-24P)
    Fig. 182 - Item #3 shows two different part numbers because there is one for the H04 & H40 codes (M984 & /A1 models, with the bigger 1710 U-joints), and the other yoke for all other models with the #1610 series U-joints.). What you need is part# 1426400W (NSN 2520-01-192-1373) Its equivalent DANA part# is 5-4-8711X, according to PartTarget, here...
    ... and only item 8 and 9 ( nut and washer)...
    Obviously they are the same for all models.

    but TM 10-14 showing oil seal, but not part number.
    Your seal would be item #13 , 113514 which has the NSN 5330-01-157-0897. Or #2AG761, directly from Oshkosh Corp.
