Had a serious issue off-roading, ranger design flaw?

[Jason B]

I was in drive while winching. The brakes were definitely engaged. It wasn't in park or anything.

In drive? Why not in neutral? Doesn't being in drive put extra load because of being engaged in the trans? I don't have 4x4. Do these Rangers have a neutral in the transfer case?

Even if there is a neutral in the transfer case on the Rangers I'm not too sure the process to get it into neutral. We don't have a simple button you can press just do that. Also when winching it's not a bad idea to have it in drive if you're trying to go forward anyways because I can help take some load off the winch once you start moving

Okay, I understand now. Have it in drive and running while winching. I was thinking winching from outside the truck and just pulling it without the engine/trans helping along.

Check out the OnX Offroad app. It shows which trails are open/closed, along with a lot of info on difficulty level etc. Like $9/year IIRC. Will display on the Ranger's main screen through Android Auto/Apple Car Play too.

I am not paying onx. Government is supposed to do it free.

My friend had his brake caliper fall off his dodge when we were on some dirt roads. We had driven a while before we noticed so no chance of finding the bolts. We sliced off the caliper and put a nail in the end of the hose with some hose clamps and drove 2hours straight to the dealership.

Maybe just a slight issue with quality control. Can report I bomb washboards at 35 mph+ and bomb dirt roads at 50-70mph if not as rutted with said washboards randomly appearing at nighttime so sometimes I feel like I’m crashing. Everything checking out few thousand miles after. Stock everything suspension wise except for rear shocks. Bottomed out into the wheel well liner a few times on said washboards going too fast and too late to stop.. and heard almost like glass was shattering, still good to go.

p.s. hi friends I haven’t seen in a while, sorry I don’t come by to comment and banter with you all.

 

[dondonbabyraptor]

yes you have been gone awhile.
thought you may have died in a high speed wreck on some washboards or something.

Hahaha, a definite good guess with my idiot way of using the Ranger. Nice seeing you RP, I had a good laugh at the RP appreciation thread but didn't have time to think of a witty comment just know I love you too, Grinch with a Grown Heart ?

Agreed.

Colorado does.

CoTrex, on Google and Apple.


OnX kinda sucks, I tried a trial of it.
Not at all impressed.

Along with what maps you can get for free(if available) I also get some trail books that have some more detailed info for specific trails. Quite handy for planning in advance.

If a rock managed to loosen the bolt I'd just call that a fluke. Maybe put some Loctite (blue) on the bolt just in case.
Was wheeling with a group of Ranger owners years ago, one guy hit a rock and broke a brake line. I said do you have any Vise Grips? He did so we pinched off the brake line with them and zip tied them to the axle.
If I encountered a locked gate in that situation, I'd use the winch to bust off the lock.

Even so, if it was leaking it would not hold pressure. Not trying to be antagonistic... just curious!

If you had a non-ABS/ESC system that would be partly true, even these have 2 hydraulic circuits after out of the MC. While the MC still has two hydraulic circuits from it on ABS/ESC vehicles when it goes into the HCU those get split into 4 circuits with HCU able to control each one independent of the others. It would be possible for the HCU to lock the brakes on any outgoing circuit with pressure while the reservoir is reporting low brake fluid. But I would think it would also require the HCU to see a pressure loss on one of the circuits to get that invasive.

Thanks for the seminar,
Still, the line that leaks and thus the device it feeds can not hold pressure.
That's partly why a school bus or a fire truck has completely redundant systems.

The HCU makes the pressure it wants on the lines it wants the pressure on. it can lock three wheels and leave one completely free to turn it if thinks that is the best thing in that moment.

While this may not be the exact system Ford is using it is likely very similar in ability
Linear Control of Switching Valve in Vehicle Hydraulic Control Unit Based on Sensorless Solenoid Position Estimation | Semantic Scholar If the programming is advanced enough it could close the inlet solenoid preventing more fluid loss though a leaking circuit, but with that path closed more fluid/pressure would go the other wheel sharing the same circuit from the MC, the outlet solenoid could be activated to relieve the needed amount of fluid to maintain even pressure between a fully functioning circuit and one that is only working at ~50% (I understand that the front and rear do not need the same amount of fluid, so it's not a 50/50 split).

?I have a friend who quit using sarcasm, saying it just doesn't work anymore !
