need help for 4wd noob

[nayala]

Hi guys..
I just bought pajero NP few monts ago, a few moment ago I drove in wet condition uphill 70 km/h and seem my car jerk and nearly spin. I enggaged on 2H. Does anyone know about this problem and the solution please

Say what?????? Do t really understand what you are talking about?????

[Ian Johnston]

Maybe wheel spin, and traction control kicking in???????????????????

I drove in wet condition uphill road, suddenly my car jerking and spinning. Do you know the cause...

Is it because the wet condition??? Do you thing I need to enggaed to 4H on this driving condition?

[Steve_H]

What do you mean by jerk and spin? Was it your gearbox shuddering or was it something like your tyres losing traction. Did your engine lose revs?

[Herman4x4]

How wet was the road? As in, was it just wet, or was it raining really heavy and there was a lot of water on the road? What sort of speed were you going? Tyre condition, lots of tread, going bald?
Cheers,
Andrew

I couldnt remember whats was happening exactly,
It was uphill windy road after rain, I run about 60-70 km then it look I lost traction for mili second....

[Herman4x4]

Maybe aquaplaned.
Cheers,
Andrew.

What model NP is it? I.e does it have stability control?

Given 70km/h on a windy road, it seems like the electronic stability control took over when the car started to slide.
If so, this is not a fault, rather it saved you from losing control.

Suggest the solution might be to just slow down a bit.
Yes 4H would help in slippery conditions.

I don't think it was the traction control as i've found that when it kicks in, the car loses power for 2-3 seconds, not millisecs as you describe.

Hi Nayala. Good on you for having a go at the Forum & admitting inexperience with 4WDriving. Driving in wet & windy conditions always increases the risk of losing road grip. Your question is "would 4H help?" in the wet.

Definitely yes. Even with good tyres on good road, you can hit patches of oil, mud, puddles, vegetation, etc that become slippery when wet.

In 2H, 100% power is applied to rear wheels, needing only one wheel to slip to lose most (depending on LSD, etc) propulsion, & leaving only one rear wheel to maintain sideways traction.

In 4H, same power applied, but split 50% between front & back, with only half the chance of losing propulsion or traction.

I especially rely on 4H in the wet for downhill because the same traction needs apply to engine retard & braking. There is less likelyhood for lock-up with effect from any wheel spread to other wheels at all times.

Thanks for the reply all, I guest the problem was like m n m mentioned....

errr sorry, but for the paj its 67% rear and 33% front in 4h.. still more stability tho..and makes sand driving a breeze

its 4hlc and 4llc that's 50/50 btw.. lol had an argument with a paj owner and me a while back and found that out

4h is good for wet weather and i put mine into 4h every time it rains.. its a 2 tonne beast and well, with physics and all tends to slip and slide easily.... so for my and my family's safety i use 4h in wet conditions.

Thanks for clarrifying that for us regulars. But I only want inexperienced drivers to understand the general principles for safety. I wouldn't even bring up diff-locking in main road travel.

Thanks guys...
I always put 4H in wet condition now
changed original tyre to dueller 697 and have a good grip in wet condition
going for off road soon
