I'm not using either one in my case. You're much better off using compatible fluid between the trans and transfer case. Why? The possibility of cross contamination is very high.

If you'd like to hear the word explode, click here:

I was just clarifying explode or implode...explode would mean a buildup of gases, likely due to heat buildup that would cause the explosion. Implode would have to do more with viscosity issues causing cavitation. On the video he says there was an additive involved with that, which I'm sure Ford either did away with or they went to LV to bypass the issue.

As far as cross contamination goes, it's a separate system separated by driveshafts from the tranny, so the only cross contamination I see possibly occurring is if someone uses the wrong fluid in either because it was handy and they didn't read the label, which is why I asked about the compatibility of mercon V and LV.

As a result, the extra little bit I have left over isn't going to end up in anything other than possibly being used as a cutting oil or something.

These fluid recommendations are a hot mess, bottom line. Ford expressly warned against using one ATF fluid in the owner's manual, until they released a TSB recommending that very same fluid. What's an owner to do, other than follow whatever they currently recommendation on their website?

Until you've pulled a transfer case fill plug and had the steady stream of fluid come out for several minutes, you won't understand. Hang around a transmission shop, and you'll see it a lot. The output shaft seal is all there is from holding that back.

An owner can fall back on a proven alternative. Not all will be aware of it and choose the recommendation. 90% of the time the recommendation is the way to go. The way they went back and forth on that is what's sketchy. No explanation, no formulation change or any kind of reason for it. It's just okay for the T case now.

Can't predict how much, but time will tell.

On an entirely different topic... it's been said that 37s are too big for these trucks, and that they will drive premature front end component failures. Is that because of the increased weight of the bigger tire, the longer lever of the larger diameter tire, or both?

On a side note... I went to the yard yesterday with my Buddy so we could get some parts for his car. We get there, and he hands me a Milwaukee 12V 1/4" impact, and a bit set.... he says, I have a couple of those - so I brought that for you to keep, but I only have one charger so just get a charger for it. LOL, so I officially have my first Milwaukee battery powered tool. I'll be honest though, I used it a bit at the yard - and I think my DeWalt has more beans.

Both, actually. Even worse is when an offset change is made, like the video I posted earlier.

Ever see it quantified anywhere? How heavy can a tire get if diameter is fixed, or how large can the diameter get if weight is held constant?

No, not that I can recall. Even just heavier off road tires will beat the **** out of the front end. The added vibration probably adds to it as well.

This horn contact ring for 83-89 Mustangs is obsolete. The ring on Frankie was broken in several places, and caused a nice squeak when I would turn. I attempted to modify a ring for a Ranger, and it didn't work out so hot. I decided to attempt a fix on the original piece by making a support that I can glue to the back side of he contact rings.



Here's the piece.... I just need to get a new tube of RTV to hold it in. Hopefully this works! I need to modify my design just a smidge in case someone else needs one. I didn't account for the base of the connector, and had to open up my slot about 1 mm on each side. Either way, this will work.
