U-Joint part number

[missionexpert]

I'm trying to determine what are the correct part numbers for the u-joints for the rear drive shaft. I unfortunately have the rear one that connects to the diff is all worn out. I'm planning on changing both ends of the shaft at the same time. When I disassembled it I noticed one was labeled SPICER U58 at the rear and SPICER U55 at the front end of the shaft. I can't find these part numbers online. I've tried searching the forum but it will not let me search for u-joint since it is looking for the letter U and it's too short a term. So if it's already been discussed, excuse my inability to find it!

U55 and U58 look to be the same size visually, but I'm not sure. Auto parts store said 5-1330x. I'm not so sure.
It's a 1992 M998.
I also searched an NSN number and found 5-213X , but not sure if the NSN number I searched is for a front or rear shaft.
Any guidance would be appreciated!

Best I can remember 1330 would be correct, I think the heavy variant uses a 1350

Look up the propshaft in TM 9-2320-280-24P. Call auto parts store and ask for the u-joint part number shown in the TM.

Thanks. While I was waiting for replies I took a caliper and measured it. Seems to be 92 mm length and 27mm dia caps. This matches with a 5-1330X.
TM shows two different part numbers for the same item, so not clear in the TM. TM lists 2-5-848X and 2-5-668X for item 21 in the propeller shaft parts list. Thanks for pointing it out, I had a different TM.

What does the image before this list look like? It shows a qty of 1. In my TM 9-2320-280-24P, the rear propshaft for the 218 transfer case has the same u-joint at each end, and a qty of 2 needed. Are you looking at the correct propshaft?

Looks like I was looking at the front, I need the rear. Based on the transfer case I have with part number 12340073-1 I need number 7 in that first part of the diagram.

The information is there, you just need to be aware of it:




This shows the HMMWV variants they're used on.

I have always seen this but how does one determine which variant he/she has?

There is a list of UOC’s near ffont of the Tm.

There should be a class or online tutorial! So if I am reading this correctly my 92 and 93 M998 should be an H13?

The basic early m998 is H13. If you have an a1 or a2 or winch, the code changes.
