Diff Locks in High Lock

[matt_grenadier]

We need to be able to use the diff locks in high range locked center diff.

It's such a hassle, you approach a difficult section when you are in high lock, then you need to
- stop the vehicle
- get it in Neutral
- set the T case to low lock
- push the brake and put back to Drive
- now keep pusing the diff lock rear for 1 sec
- keep pushing the diff lock front for 1 sec

For a vehicle that is about simplification, this is such a hassle, also all the nanny systems in place are terribly annoying. And then you still need be lucky that your t-case shifts smooth to low range, this is known to be an issue, sometimes you need to keep the vehicle rolling a bit to be able to shift to low lock.

Like in old military vehicles like the bombardier iltis, this used to be so simple to get diff locks on, just flick 2 switches, and done, no conditions etc, and extra steps, no nannies.

Locking the diffs in the grenadier should be very simple, just push the diff lock button, and then done. Then you can also keep your momentum on the trails, no need for stopping.

Petition for this software change!

I 100% agree, but I understand the Ineos mentality. Realistically 99% of owners will use it wrong and try to claim warranty. It would never happen, but I would very quickly sign a "warranty voided" terms and conditions in regards to locker use. Some day maybe the CAN Bus will be fully decoded and we can create an electronic bypass.

I have only used the centre lock in low range so far and haven't come across any time I wanted the centre or rear locked in high range.
I haven't driven on snow or high speed sand though.
Fastest I have gone with centre diff locked is about 60 KMH

What situation are you in that you are using high centre lock?

 

[Nevada Grenadier]

I mean you can use all 8 gears in Low and go 45 mph.

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 find the centre lock high works well on long dirt road runs at speed because the ESC is switched off which avoids the braking and slowing down if you lose traction, which happens regularly on dirt and sand. Centre lock and Off road mode definately for sand, not sure about the snow but I think it would be the same.

 

[Dokatd]

I used center lock in my D90 all the time in snow and ice.

 

[AaronS]

I almost always lock the center diff when on dirt... I don't really pay attention, probably up to around 60-65mph.

I used to admin a pickup forum. As you may know most have an an old school method to lock in the front wheel drive with no centre diff.

The number of people with wrecked transfer cases/front diffs/cvs by driving in 4x4 on normal roads was astounding.

I get why IA have made it somewhat idiot proof

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.

Just driving in the woods on a dirt road, and a difficult section approaches. The road becomes steeper, and a small creek is crossing the road diagonally.

I know, if i am just in High lock, chances are high both wheels will spin, so I just want to push both (or in some situations, only rear is enough) my diff lock buttons, slowly pass the difficult section, turn off the diff locks again, and move on. Very simply.

I used to come across many situations like this. And the way the grenadier is setup, is very similar to these old jeeps with mechanical locks. It has very little traction control advantage in these situations, so the diffs will be required. But the electronics prevent us from using the front and rear locks smoothly, like we used to in purely mechanical vehicles.

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.

I must admit I’d prefer mechanical actuation of the lockers but I also understand why Ineos have done it this way. Not all users will be mechanically sympathetic or, let’s face it, will RTFM*

Some people feel Magna Steyr should have developed the Ineos around their personalised requirements.
I'm not one of them.

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

To activate the Merc G wagen diff locks, you simply press a button in either high or low range . I don't understand why the guys at Maga didn't apply the same logic, after all they also designed the G wagen.

Because G wagen owners are city slickers with 26" wheels and no muscles?

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

Yes indeed!

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.
