Flat towing of grenadier

[Lt403]

Why can’t this vehicle be flat towed? I am surprised that this is not available .
It would be another option to be towed behind an RV

The transfer case does not have a neutral position. Unlike the classic Defender and mo
st part time 4WD's.

I though you crawl under it and screw the set screw in...than puts the transfer case in neutral.

It does.

The user manual warns you not to flat tow it any real distance.

That it does.
It isn't that big of a job to disconnect both driveshafts from axles and suspend them for towing.

I'm learning to being more aware about how old my knowledge is, but most autos don't have a rear oil pump just one in the front driven by the engine via the torque converter. The engine needs to be running to make oil pressure for transmission cooling, cleaning, lubrication and control. Towing an auto any significant distance or at speed with the transmission output shaft being driven by the drivetrain will do damage to the transmission due to a lack of oil pressure.
Caveat: I cannot confirm if the ZF8HPx series has a rear oil pump.

The Grenadier has the neutral stop bolt in the transfer case to isolate the auto transmission from the drivetrain (and circumvent the auto trans parking pawl if the vehicle is inoperable), but I'm of the opinion this method is only so the vehicle can be recovered onto a flatbed trailer hence the warning in the owner's manual.

Not via the Transfer Lever, unlike the examples i provided

No, but there's a neutral. My guess is INEOS is not certain the t-case will stay in neutral forever, and for fear of a catastrophic breakdown they say don't tow it for any extended duration.

 

[Mike Morrison]

Why Ineos elected not to have a neutral and have to climb under the vehicle malarkey is anyone’s guess.
There is so much they got right, but things like this makes one wonder if the engineers were overridden by the suits and beancounters.

Where neutral is selected within the transfer case gear train and how this effects the lubrication would be the reason the the car can't be flat towed long distances.

I am constantly asked if the Grenadier can be Dinghy towed (4 down flat towed). Our shop does many of these modifications but I can't get a solid answer so far. I must say, if it can be dinghy towed that would be a game changer!

 

[Weatherman]

I'm more concerned about long distance dead towing (up to 25 miles) at low speeds for off-road recovery. It's not hard to imagine a mechanical failure in the back country. It seems like the manually putting it into neutral using the bolt in transfer case and then praying is really the only practical option.

There is a solid answer, no! There are warnings in the handbook, even after the neutral bolt has been wound in.

Why I don't know, but oil pumps in the transmission are not uncommon. If you have to tow it flat for any distance, I guess you have to take the props off.

 

[LabRat]

Agree it's a big miss. Would love to tow one behind my RV without having to throw it on a trailer. Lots of Jeeps out there as TOADs

 

[landmannnn]

While the Jeep for example can be flat towed, none of these can be: Grenadier, Defender, LandCruiser, G wagen unless in an emergency situaton.

 

[LeeroyJ]

What's the downside of just putting it on a trailer behind an RV? The cost of the trailer of course, and needing to have room at your camping site for the trailer, RV, and Grenadier. I guess the added weight of the trailer too. But other than those three, is a trailer problematic? Less mechanical wear on the IG, and probably easier to get a trailer that brakes than to make the IG brake?

I'm just curious, not trying to advocate one over the other.

Defender or New Defender? Land Cruiser...? There are so much...which ones?

Simple answer, Grenadier is all time AWD. Where the jeep can be shifted to 2 wheel drive.

Biggest issue is what to do with the trailer when you get to where you are going. If you've got a 45' Class A and pull into a place needing to store both a 20-24' trailer and park an IG, that's a lot of space. Trailers are good because you can back up without having to unhook your car and as you said, less wear and tear on the car.
