4wd how to engage

[batosai]

Sir need help, My ride is isuzu bighorn ask ko lang po panu po ba ang tamang step ng pag shift ng 4wd low? kailangan ko po ba mag full stop at place sa nuetral ang transmission ko bago ko mag engage ng 4wd, tapos pag mag dis engage naman po panu din? Kailangan ko pa po ba umatras para ma dis engage ung mga bearing sa front tire? Auto Hub po ung bighorn. And ask ko na din difference ng 4wd low at 4wd high? What is tha maximum speed na pede ko patakbuhin ang vehicle kapag naka engage sa 4L at 4H.


Tnx and more power

if you want to engage to 4low. full stop. trans in neutral. then shift 4low. same with dis-engaging.

you need to do a reverse if the 4x4 light in the dashboard is still lit upon dis-engaging. the hub is auto. i havent experience our trooper (96 local) that goy stuck on 4x4 that i had to reverse to dis-engage.

max speed in the owner's manual was 60kph i think or 80kph. safe side is max 60kph when shifting from 4x2 to 4Hi (running ofcourse).

max speed for 4hi? wala sa manual e.

max speed for 4low? well till it doesnt over rev. so check your rpm (redline).

Sir Baker123,

Thanks, follow up lng po kailan po ba pwede gamitin ang 4h?

[coiter]

wala sa manual or sa sun visor ng driver's side ang instructions?

well sa akin ganito:

2H to 4H - shift on the fly (meaning while moving) up to 40 kph. ganun din to disengage.
4h to 4L - complete stop. put transmission in neutral. step on the clutch pedal and quickly/seamlessly shift to 4L. ganun din to disengage.

to disengage the auto hub, go in the reverse direction for about 1 meter.

as much as possible, don't use 4wd on concrete or hard surfaces as it may cause "binding" and damage the transfer case.

4H is used for gravel or sand. 4L is used for mud, snow or rocks.

use 4wd only when applicable (stuck in mud, very very steep ascents, etc.). so unless you're into hard core trailing or cross muddy or sandy terrains, you'd probably never use 4wd.

hi batosai. 4hi can be used on slippery conditions like wet roads or gravel roads. beach sand also. what i usually do, here in isabela when traveling, is engage 4hi when the road is about to turn into gravel (example e yung hinuhukay ng mga dpwh na di nila matapos tapos) then just when im about to go to cemented roads again i shift (on the fly) to 4x2. note that you should be running on controllable speeds. caution lang batosai. the 4x4 mechanism, either the 4hi or 4low, is not a license to drive hap hazardly. it just gives us drivers more control when the going gets tough. try it first on low speeds.

4low meanwhile as mentioned by Coiter is used on really sticky situations. this includes muddy terrain and small river crossings. things like that. and steep uphills or downhills (as long as not paved/cemented roads). 4low also has the benefit of a lower gear thus giving you more torque. this helps when you get stuck or going uphills.

So for example po sir I will go to bagauio through canon road I cannot engage my 4H to add more torque because of its a cement or aspalt road, its only advisable when crossing through slippery surface like crossing through grassy road. Tama po ba? And by the way sir AT trans po aq so same lng din process put the gear to neutral and then engage 4H or 4L. To dis engage stop put to neutral put to 2H and then back a bit to dis engage the hub. Tama po ba ulit?

tama, hindi advisable gamitin ang 4h or 4l sa concrete or asphalt. lalo na paakyat ng baguio na paliko liko. mahaba explanation nito kung bakit hindi pwede, pero ang bottomline e masisira transfer case mo.

tama Batosai. mechanical problems (plural yan ha hehehe) aabutin mo pag ginamit mo ang 4x4 sa paved roads. kokontra kasi yung 4 wheels thats trying to rotate at the same speed. ganito ang parang short sample/ explanation. if going left turn on 4x4 mode. yung inner wheels (left side tires front and back) will rotate much less than the outside tires (which is your 2 right tires). now imagine those wheels supposedly rotating at the same speed then biglang nag karoon ng difference in rotation (kasi nga lumiliko). dun na masisira yung drivetrain system mo. lalo na at hindi sya dumudulas. hindi mag co compensate yung inner wheels sa outside wheels thats also trying to turn, but wider and more rotations. so yung axles may possiblity maputl or yung buong car mismo ang hihinto kasi hindi maka usad at nag lock yung rotation ng wheels. kumontra sila 4 tires.

regarding sa pag engage ng 4x4. yes put in neutral first then select 4hi or 4low, if from 4x2. reversing the suv is not necessary unless naka ilaw pa rin yung 4x4 sa dashboard mo. if it lits. it means its still engage. then do a reverse until 4x4 light is gone. dont forget that you should be switching to 4low ONLY when you are Completely Stop.

also have the presence of mind. minsan kasi sobrang saya playing with the 4x4 that we forget to switch back to 4x2 mode. we have a family friend with a ford F150 lariat, which they bought from my brother. uncle went to the farm. switch to 4low (para daw sigurado di sya mabalaho) then to the fields and such. after a while. fuel was going empty. so he went to the gas station. while in the highway (his house is near the highway so straight lang sya) he was wondering why the truck somehow lost speed. seeing he was nearing empty. he taught maybe because he was low on fuel. and so he went. full tank after. when trying to leave the gas station is when he really felt that tires fighting. then he realized he was in 4low. they had to call casa to fix it. there were signs of overheating sa fluids ng drive train. pinalitan differential.

oh yea. he did this twice. hahaha. tinanggal na ng Ford Casa yung 4x4 differential nya para walang accidents. ayun 4x2 nalang sya. di pa rin naman na babalaho. next tiem ill check if the switch is still on 4low. hehehe
