Humvee- Geared Hub Seals

Read the Technical Manual but check this out if you’re interested. Do get new locking washers and new 8 notch spindle nuts. There are other, even more secure, spindle nuts out there. Research those. Also, be prepared to buy any new bearings and the “spacer” gaskets that I mention. You may need them. I feel that I did not need those. Get some brakeclean to get the nooks and cranny’s clean. Clean up your gasket surfaces throughly prior to reassembly. I used Teflon tape to seal up my three screw in plugs. We’ll see how that works for me. Your comments will help the next man. Thanks for watching.

I don't think I've ever seen this tie rod removal technique, I simply whack the mating surface area around the tapered tie rod end, the knuckle, and the shock pops the tie rod free. The same is true with the ball joints.

I’m currently changing the outboard seal on my hub. The leak was dripping onto the inner wheel assembly, and down the inner sidewall of the tire.

Nice, your HMMWV came with CTIS spindles? It must be a newer variant. I bought and installed CTIS spindles on my M998. All 4 would deflate no issues but when inflating 1 spindle seal leaks air into the the hub itself then continue to pressurize transfer case which then bubbles up out my transmission dipstick. Man I've taken this 1 hub apart multiple times to try to replace the seal but havent figured out a way to remove that old seal to replace with new. I am really struggling to get that done. I wish you made a video replacing that seal because the way you make your videos is very easy to follow.

I just finished replacing the CTIS seal and it was in TIGHT. So tight that i couldn't simply pry it out. I ended up carefully drilling into the seal (don't drill to far) then used a screw to pry it up. Hope this helps.

@@Drop-Kick-69 Good to know I wasn’t just being too soft on the seal. I was mainly concerned about damaging the steering arm cover. I guess it actually require some serious persuasion. I will try that next time I have a whole weekend off work. Thx for sharing.

Have you got part number of those hub seals or maybe dimensions etc...
Thx Rob

Why take off the half shaft? It’s easier to remove the hub and refurb it on a bench.

That seal is in completely backwards!!!!! No one has seen that?? The green one! Completely wrong!
