Will reversing straight in 4L cause wind up?

[ryannnnnnnn]

Hey guys

Hope this is the right category to post in. I am looking at a trailer boat that will be about 2 tonnes and will need to reverse it up my steep drive way (about 20 meters) quite regularly. Will need to use 4LLC to get it up and given my drive way is concrete and has a slight bend in it, am I likely to bugger the transmission or something else? Have a 2016 auto MQ glx (it has easy select with 4L, which is the equivelant to 4LLC in super select) .

Will I cause damage reversing in a straight line in 4LLC or does the risk of damage only really apply when making turns?

Only when turning and the traction levels on the tyres are higher than what the transfer case is producing. Straight lines are no issue. In other brands there are work arounds so you can go low range and not lock the centre diff. It is usually as simple as disabling a sensor and installing a switch. I have no doubt there will be a switching solution for your car on a forum if you look.

There's no centre diff with easy select. Reversing in a straight line won't wind it up but in my experience, reversing a trailer is rarely in a straight line.

My brother has been doing this fine in his MN up his steep driveway - less wear than hammering the clutch trying to get it up there.

You will soon know if you have lots of wind up as you will feel it and when you unlock it it will clunk

So it will have a simple solenoid up in the front diff somewhere for the release actuator? I have no idea about Mitsi systems, never had one. Sounds like the ADD system in the SR5 Hilix though which is an easy fix for low range 2wd.

From investigations we have done there is no release mechanism, front diff is always engaged (as my ranger was too)

Could be as easy as pulling a fuse either before or after selecting low range then?

@ryannnnnnnn Fitting free wheeling hubs to the front is the usual way to deal with your situation

Or just bite the bullet and buy a car that can select low range without locking the transfer case

“Never, never let a chance go by”

 

[discomatt]

I am sure there would be plenty of manufacturers that have the ability to select low range without locking it all up surely??!!
It was never a buy a LR comment, the thought never even entered my head

Imagine how hard it would be getting up the drive with oil stains all over it Matt

 

[discomatt]

I find it handy for keeping the weeds down

 

[ryannnnnnnn]

Interesting comments thanks guys! Reversed it up in low and it went up easy. If I extend my driveway so it can go up as straight as possible (less need to curve the trailer) that might help prevent wind up by the sounds of it?

should driving back down the same distance not 'unwind' it ? nice boat btw, whats powering it ?

 

[Albynsw]

I think the best solution would be to keep the boat at my place

It will be a 150 yammy on the back and will have a big minn kota electric motor on the front. Has a hard top which is folded down in the photo to fit into the shed

I thought the same, then did some research. Apparently(?) you can't fit free wheeling hubs to late model Tritons due to the design of the hubs (splines on the inside of the hub, rather than normal outside).
Appears from OP's pic that the driveway isn't much of a concern IMO, so no need to panic. Contact Mitsubishi with the pics and description of the issue and get their advice if in doubt.
P.S. from the pic I can't see why you can't back it up in normal 2WD

Just put a winch at the back of your garage and push the draw bar to steer ? I would use a pole to steer just in case you don’t hook it up well.

a quick look on eBay there seem to be a couple of 1000 kg 240v units for a couple of hundred $$

And Disco was talking about the Prado. Apparently you can go L4 without locking the centre diff from 2019. Yet to try it though.

Correct - my 2011 Prado GXL has a centre diff lock you have to select deliberately in all situations. It's never selected for you. Power is always "4x4" with traction control taking care of most locker-like situations. LR does switch off stability control, which makes sense.
