That would actually make it worse. The way u-joints work - at anything other than zero angle they don't rotate with constant velocity (thus the differentiation between a u-joint and any of the "CV" or Constant Velocity joints). As they rotate through 360 degrees they speed up and slow down and...

Yep. If you are keeping the hub reductions (especially the LMTV with the low pinion diff) you need to change the u-joints every 15k miles, and grease them every 3-5k miles. You can probably double that with the ECO hubs but the low pinion 4x4's shouldn't go over 30k even with ECO hubs IMO. The...

Yes. 7.8:1 final drive with the hub reductions. And it destroys the engines, transmissions, drivelines, etc. All that junk is turning 120 mph equivalent at 60 mph road speed. That's why the military's testing showed a MTBF of ~35,000 miles. And they are perfectly OK with that. If you aren't I...

From what I understand the oil level feature is optional and the military didn't opt for it. Maybe it doesn't apply to our extra-deep pan or possibly the controller doesn't have enough GPIO to assign for that function with our AWD and extra 1st gear low range..... IDK but I'm about 99.95%...

I drive a WTEC IV, but my display says "NN" with ignition on, engine off. And N means neutral which indicates it should be ready to run the starter. My guess is you have something going on with the crank circuit.... But the transmission at least *thinks* you are good to start. Haven't proven...

Interesting - I thought our transmissions didn't have the fluid level sensing option. I haven't run across any evidence of it anyway.

Huh. Well I would say that since it slowed down significantly you probably at least have touched the source of the fluid. Is there any special tools for centering that front seal flange? Did the TC seal get replaced again when the plate was re-sealed? How is the TC seal surface? Perhaps you need...

:LOL: No. The required tools list for wheel bearing service does not include either one. There are brass drifts and punches in the general mechanics tool set. The only special tools required are the CTIS seal driver, the inner hub grease seal driver, and the 3-7/8" x 7" spindle nut socket. In...

Correct. They are unrelated. I had one wheel (font right) that had gear oil in the CTIS stud. All my bearings had grease though. That's wild and I can only imagine the horror that would have followed if you hadn't found that till it seized. For cleaning the spindle - red/brown scotch brite...

Right - the Amsoil is >500 dropping point. The 315 number is just calcium sulfate greases in general which aren't necessarily synthetic. The high end synthetics are pretty dang high. I like the Amsoil because it's specifically formulated for moist environments and these trucks are rated for...

The Amsoil grease I use is a calcium sulfonate complex rather than a lithium complex. The calcium sulfonate has a dropping point of 315 degrees vs the lithium complex of 260 degrees. It also has greater shear stability, better water resistance, and higher pressure protection. It's better in...

Ultimately it's just wheel bearing grease. I used Amsoil blue waterproof grease on all the trucks I've done hub services and ECO hubs on. No issues at all. https://www.amsoil.com/p/amsoil-100-synthetic-water-resistant-grease-gwr/ I suppose the military likes the yellow because you can tell...

GAA. Grease, Automotive and Artillery. It's Yellow. It's grease. :poop:

Where did your truck come from? I am curious who may be responsible for such an oversight.

WOOF! That's not good. Looks like PVT Snuffy didn't pack it with grease. Now you get to pull them all off and check them all. That SUCKS.

When you reprogram the A1+ truck ECM to correct the speedo that same signal is used by the CTIS controller so it will go to over speed warning at the same ~65 mph that it always did. But you can pop into the Dana software and change the HWY over speed warning to whatever you want.

If you like, you can send me your ECM and I can flash it to 330 HP and make all the changes for pulse per mile and cruise enable, etc. Can also clone the ECM if you want to carry a spare. CAT generally can't or won't do that with a used ECM and new ones for the 3126 are crazy expensive from...

Broke a 1/2" extension doing mine. Breaker bar and a cheater pipe and some swearing. Fortunately my truck was a Kuwait/TX stationed truck and a 2008 so most of my problems are related to mud dobbers and the two dust bowls she lives in. Very little actual rust. I pity the guy that has an A0...

Might be ok for a short time. They have an expiration for good reasons. I wouldn't bother with them personally. That means they were made in 2009 most likely. Like old tires they will disintegrate surprisingly quickly once they start seeing use and flex, etc. Gotta love the surplus scalpers...
