Using 2L speeds

[dani4JB1T]

I have Superwinch manual hubs in my 4bee since 2,5 months ago.
Today I select 4L with the hubs unlocked (4x2) and I could drive the car in 2L. Took the car to a soft ground for check the wheels turning... as I supposed I was driving correctly in 2L, because the front wheels didn`t slip on the ground. Didn`t notice any trouble with this new speeds (well just did no more than 3 slow turns to the square, and a few meters on the dust).

Is this healthy for the transmission system??...can I say now I have 24 speeds in my car ....would I have any problems in the future If i drive it in that way ...of course it can`t drive fast in 2L.

cheers all
Dani

comes in very handy for towing heavy objects and heavy trailers up steep grades etc
no harm done unless you do something ironic like trying to drive at 100 kms in 2l lol

[dani4JB1T]

yeahh...i`m pretty sure it is OK.

thanks!

24 speed?? 5 speed 2h or 4h + 5 speed 4l or if hubs unlocked 2l. = 10 speed
Ive used mine in 2l many times with no bad effect but its wouldnt be wise if you still had auto hubs.
This brings up an interesting question for those with auto hubs. The book recomends driving 20k a month with the hubs locked to spread lubrication etc. But your not allowed to drive 4wd on hard surfaces. With auto hubs how do you achieve this?

2WD 2H : 1,2,3,4,5,R
2WD 2L : " " "
4WD 4H : " " "
4WD 4L : " " "
Total: 24 speed

Is that right, isn`t it ??

oh. just on more question Alan...What is your rear prop shaft outside diameter ??...mine is 2,7", innner 2.5". I have seen in second gen Bighorns (3.1) bigger prop shafts, don`t know how is that in early 2.8 Bighorns like yours.

I ask just for be sure that I don`t going to stress my propeller shaft....the rest is the same as you, 12 bolts diff, 26 splines, so no prob with them.

2/4 H
2/4 L
12 if you count reverse

[geeves]

The ratios are the same in 2wd and 4wd but I missed reverse
Ill measure the prop shaft in the morning when I can see my spare one in the basement.A clue might be that it uses the same universal joints as a Hilux

[dani4JB1T]

cosidering that in early MUA gearboxes I can shift from 4H <--> 4L at low speed. A shifting from 2H <--> 2L it wouldn`t be dangerous to do, right ??

[pig75]

There is no 2L just 4L. With your front hubs out and going from 2H to 4H the gear box will not like it unless you have a shift on the fly box which are late model boxes. Once you are in 4H shifting to 4L can be done at slow speed.

[dani4JB1T]

yes...i understand there isn`t 2L in our 4bees, but when I shift 4L with the manual hubs unlocked (4x2) I send a reduced torque only to rear wheels (not sure if by 2.28 or 2.5 times), that is what I call "2L", two wheels (rear) with extra torque. so there I have new different speeds limits to any 4wd mode (just a little difference), because front wheels doesn`t work there. Today I test shifting 4L with the hubs unlocked at very low speed, using the cluth of course, and works fine. This is not for do it all the time, Im just trying to know more about my car...that`s all.

[pig75]

There should be no difference in speed from having your hubs in or out

[geeves]

Shifting from high to low and back is deffinatly a nono according to the book! there is no sychros and the transfer case has straight cut gears which dont like that sort of thing. If done it many times at less than 10kph whith box in neutral and clutch in without any nasty noises.

[Graham]

I can only assume there'd be no harm in using 4L without the front hubs (effectively 2L).

I've shifted into to and from all 4L/4H/2H gears while moving in my auto, and as long as you aren't going too fast and don't have the engine under load then it seems to handle it fine. I was once barrelling down a dirt road and decided 2H was a little slippery so went to 4H once I found a straight bit, probably doing about 60 kph. I think I put the auto into Neutral for that one.

Cheers! Graham

I regularly use 4L with the hubs disengauged for backing trailers, etc, and as long as you only engauge and disingauge whlist stationary you will be fine, As for sychros and shifting from hi to low, i do it regularly as well under 20km/h, just press the clutch take it out of gear (1,2,3,4 or 5) relase clutch, press clutch again, select hi or low or what ever and then seclect a matching gear to the speed i'm traveling and go, i also change from 4H to 2H with the hubs locked on the fly (up to 80km/h) with no trouble whatsoever,
but thats just my 2 cents.

[geeves]

If you have manual hubs then you can change from 2h to 4h and back at up to 100kph if the hubs are already locked That way front and rear diffs are going at the same speed. Auto hubs you have to stop as the hubs have to sence a change of direction to lock.

I just recently done a 3'' body lift, and ever since this my 4L keeps on popping out of gear when im on 4L.
What is the problem, anyone out there can help me out on this?

[mulover]

Hehe, a bit of a problem aye!!, ive done a 35mm lift and i have to check its still in 4 low a lot, if you look underneath you will probably find it is to do with the boot thats inbetween the gearbox and the floor, i'd say because of the lift the lever is travling further in the same hole due to pivoting points, etc, let us know!!

[darkhunter]

hehe,i was looking at that on my trooper as i was looking at what changes in a body lift(was contemplating doing lift,latter i say)and noticed the boot problem ,and came up with dropping tunnel section to compensate for that or seeing if i could make boot invert downwards so to alleiviate that problem
