U-Joint bolts...

[spankybear]

Well I need some new U-joint bolts... and I am having a heck of a time finding them. Now the military uses a break away type and I have only found some on the e auction place and the seller wants like 14 bucks each.... I aint doing that. I am looking for the Spicer 5-73-109 that is used with the lockstrap. I can't find anyone that has these in stocks.

In my quest I find this https://www.logsa.army.mil/psmag/archives/PS2017/773/773-16.pdf and this says not to use the ones with the lock strap.

So 1) what have you used and 2) where did you get them?

Spicer 5-279x joints do not come with the straps. That is a 1610 u joint that the LMTVs use

They will have locktite on the bolts.

Precision 333 u joint is the equal to a 5-279x joint and has the straps. It just depends on the maker not everyone of them believes in the straps.. Meritor CP16Ns can come with or without straps.

I do not use the straps on any 1610 or 1710 joint i use even in 600hp applications

the bolts themselves are simply 5/16 fine thread that are .5 inch long grade 8 or L9 whichever you want to use.

The driveline shop installed straps on the one u joint they installed. I wanted to new bolts of the other joint. Thought straps where a thing. What torque do you install and do you use blue or red loctite?

I think it's 17-23 ft*lb. Blue Loctite 273.

To be clear, it's not saying to not use thread sealant (Loctite) or metal bend tabs, it's saying not to use the bolts that come that way, since they want mechanics to stop over/under tightening the bolts and use the new idiot-proof bolts that snap off so they can't screw it up.

Blue/red. Doesn't matter. Not much is needed.

If you wanted that u joint kit the PS magazine refers to it is meritor CP16N18S
