Diff Locks in High Lock

[matt_grenadier]

Not many vehicles use mechanical diff locks anymore.
They are either electric or pneumatic.
Even the ones with a simple selector still have electric controls.
The flashing lights are the problem.
Just ignore them

No, i mean that the grenadier does not rely on traction control options like the modern land cruiser or defender, therefore, it should be a very easy process to lock the diffs.

I'm a real fan of low range. I use it practically always when speed is anyhow slow and conditions may get suddenly worse. And CDL is used way before it will be needed.

I also noted the high revs but they are needed with automatic gearbox to avoid unneccesary stopping of the car because lack of torque. But I use manual shifting on easy tracks to keep revs reasonable. And for more difficult ones I either downshift in advance or use D.

Yes indeed, manual shifting in Low range to keep revs under control seems like the way to go! Thanks for your response!

Really, i have never heard of such cases. If we can operate a 2.7 ton truck safely on the roads, sure we can also safely operate 2 buttons to lock the diff. It's not rocket science.

I have done a lot of offroad driving with military jeeps, where you could lock front and rear with a mechanical switch. Very easy to operate, no safety conditions, never had any problems myself, or any one i knew.

Actually fairly common amongst the pickup fraternity.
Actually from personal experience, I had a battle with several of my colleagues using pickups to go airport airside. The left their Toyota in 4hi all the time, complaining about the steering too. Being a Toyota it just wrecked the front tyres.

I am not a big fan of driving in Low range, maybe only very steep and technical sections.

In low range, the revs go way to high, and you are 2000-3000 rpm just driving a smooth section, making a lot of noise. I am a big fan of smooth driving, and that's not working well in Low range

99% of my off-road driving I can do in high range lock, just manually switch to First gear High for some steeper sections, it's ratio is low enough for most cases.

And a lot of heat, especially where it’s already hot. I can drive most trails around here in 4H with the center locked, except for a few sections where I need the lockers. After some frustration using them the first time the next few times I ran the whole trails in 4L triple locked. The fans were constantly running, and I can’t confirm it I think it being that hot stopped wading mode from being able to work.

After 18 months I’ve gotten better at turning the lockers on quickly, as needed, and with no cursing, but saving the step between 4H and 4L would be nicer

I have seen a couple of cases where people have snapped an axle.
With the grenadier you could still use centre lock if needed and remove the broken axle.
Problem is when many 4WDS are only rwd as standard.
Grenadier you could still drive with only front axle driven

Or remove the drive shaft in some cases.

Wading mode automatically turns off if you go over 30 kmh or after 20 minutes.

I'm probably the odd one out here, but I enjoy the process of working with the vehicle to match the driving conditions. When I drive my Grenadier, I'm not in a rush and having to switch gears, lockers on/off and so forth; it actually helps me slow down and think about what I'm doing or should be doing. For me, it's part of the fun.

I do see the benefits of simplicity though, not arguing with that. My point is just that it's not an issue at all for me, I'm just happy to be driving such a beast with all these capabilities at my finger tips!

There are desert runs here in western US that can be run at 50+mph easily. That said, center lock is not overly necessary. My issue is not so much speed, but just any condition requirement.

Snow and Ice can be an issue as well but you better know what you're doing at speed with lockers on in snow or ice. Doing this in high range can most certainly be beneficial. Revving out at 45mph is not ideal.

I did a fair bit of high speed sand driving in namibia. Up to 80kph on off-road mode was perfect, no traction control or EsC. But it disengaged at 80kph which is annoying. Apparent fix is to pull the ABS fuse (no 6 I vaguely recall) and that is a perfectly fine albeit manual fix to the high speed in off-road sandy conditions losing momentum from traction control problem. Ineos were given feedback and they might make this more configurable in the future . Of note I also did a fair bit of higher speed driving in sand and desert dirt roads up to 135kph and it handled just fine without any lockers or special settings engaged.
