What have you done to your HMMWV today/lately

[rcamacho]

LF lower ball joint replaced. Installed Centramatic balancers on the front axles.

We took a group video of some completed projects, all have been through and driven extensively

Did you fabricate the rear bumper step on the ecv?

 

[GuntherRommel]

No those were bought, nothing was fabricated but they are a very simple design and would be easy to copy if you were inclined.

Could you point me to the source?

finally got my Vic-3 four ffcs stations installed along with dual bluetooth (plugged into A and B radio ports). I know the ffcs with four is overkill for a hmmwv but i could so i did. mounted each one within easy access to each seat, and with dual bluetooth, can have two cell phones connected and talk, stream, etc. next up will be a RIT installation with a marine radio and a ham radio. it was "easy" to install. Ask me any questions. the hardest item was procuring the "correct" length highway cables.

those beige boxes are the bluetooth and they are just there until i can get a dual box 3d printed to replace them. If you want bluetooth, #augi on this board is the developer. exellent solution!!!

I recently noticed that my fan began cycling on and off very quickly even when the truck hadn't even warmed up properly. Today, I installed an OEM thermostatic switch and noticed that the original which came with the truck looks quite different. Wondering if the USMC accidently received a batch of aftermarket parts.
Will test run tomorrow to confirm proper function.
Original on left, OEM replacement on right.
Post Test Drive Update: Fan operates normally and closer to advertised temps. Cycles on at approx 220 and back off when approx 200-210. The original thermostatic switch ran the truck cooler when it was operating (cycled on at approx 200 and off after cooling down several degrees). I suspect it was an aftermarket replacement even though it was installed original to the truck.

Front toe adjustment after replacing TRE, lower ball joints, Pittman arm, idler arm and rebuilding steering gear. I was within 1/4” visually before adjustment .

Made some slip/turn plates which helped immensely. Toe set at 0 +\- 1/4” with my lack of accuracy.

I’ll likely use the full string method after I get the rear suspension sorted.

The blue tagged sensor is the only mil-spec sensor, even AMG got stung, wound up with hundreds of Chinesium versions that were claimed to meet spec. There is a discussion about it back in Jan/Feb.

Trying panel plugs for armor hole fill. Like that they are readily available and non ferrous.

I may go to bolts with nylon shoulder washers in the future.

I just used stainless bolts and nuts. Lot of them. I think it gives the truck a rugged finished look.

I hope you used some contact washers or coating on those fasteners to stop galvanic corrosion... Stainless and aluminum do not play well

Yep like he said.

Since the aluminum is painted he will probably get away with it.

Finished installing missing LH upper cargo shell close out piece.

Lots of corrosion and drill damage to repair as well. Of note I was pleasantly surprised to find corrosion prevention tape factory installed between the cargo shell and upper hinge latches.

I use washers on both sides and everything is metal primed and then surface painted. but yeah, my truck is a battery. my adds are stainless, then the existing bolts are anodized steel, there are some chromium plated bolts, and then steel plates, different types of AL, brackets, etc.

Some nylon washers would be really good. The nylon would keep the dis-similar metals apart except where the bolt touches the aluminum - and if you were careful - even that could be avoided...

Here is a good article on aluminum and stainless:

Stainless Steel & Aluminum: Why You Shouldn't Use Them Together

Why Can’t You Use Stainless Steel and Aluminium Together? What is Galvanic Erosion, how it works and, how to stop it? Read More...

www.albanycountyfasteners.com

Interesting excerpt:

"The other situation in which these materials can be used together with little impact on rust prevention is if the cathode area is very small when compared to the anode area. For example, if the base material is a large sheet of aluminum, then using very small stainless steel screws will not dramatically decrease the life. Conversely, if you use aluminum to attach a large sheet of stainless steel, the aluminum life will be dramatically shortened."

Seems to me like avoiding it is the best practice. But a stainless bolt here and there with paint as an insulator will probably be okay.

Please report if replacing this piece makes any difference with keeping rain out. Thanks!
