WHEN DO I USE 4x4 OPTION.

Not at all - the later T2 MkIVs didn't have freewheling hubs at all, no harm is done drivig with the front diff turning in 2wd. Infact it is good practice to do just that every now and again if you don't use 4wd regularly so as to keep everything free and stir the oil around etc.

I thought so.

when the 4x4 light goes out does that mean the auto hubs have turned off?

[zippy656]

nope, means the lever is back in 2wd...

Question - "when should I use 4x4"

Answer - before you need it!


Reading the terrain in front of you is the most important and first off-roading skill you should use. If it looks like you may need 4x4 select it, dont wait to see if you need it!

I was a boy Scout and I stand by their motto... BE PREPARED!

Just make sure 2wd is selected if driving on dry tarmac, anything else such as slush, ice, snow, mud, grass, gravel you are fine keeping it in 4x4 High.

Only use 4x4 low if you require extra torque (recovering or climbing v steep slopes) being in low box can actually get you stuck sometimes in snow! Too much torque or power = wheel slip in snow

ENJOY!!!

But it doesn't turn off as soon as you put it in 2wd. You drive forward/reverse a few meters it goes off.

mine turns off as soon as i move the lever and more forwards again.

Nor does mone. I checked it the other night in anticipation of the snow to come. I have always engaged 4WD at a standstill in nuetral and disengaged it driving slowly (15/20mph) in a straight line.

The light usually goes out 10 or 15 seconds later, so it can't be just a switch on the lever surely?

Ya light will only go on when 4WD H / L is selected & will go off when back in 2WD. (instant)

As Simon has said i've never bothered going back an forth to deselect the auot hubs & i've had no problems in 18 months...

To disengage the Auto hubs having been in 4 wheel drive, select 2 wheel drive and then you drive the vehicle in the opposite direction for 2 metres to what you were going before.


Well I have managed to make a prototype for my front prop shaft, that detects if the prop shaft is still turning, when in 2 wheel drive, so I know that the hubs are still engaged.
Only taken 15 years to get round to this, I'll let you know if it works.
If I am on the look out for manual hubs, then you will know it didn't....

The sensor was the most expensive part as it needs to work with crud, salt and water.

[dropdedfred]

no one ever told me to reverse it after... just go from snow 4 wheel then onto clear rd change into 2 always going forward.... hope this hasnt cost me

[wildbri]

no damage will be done, if the hubs stay locked in 2 wd the drive shafts just rotate, might use a little more fuel and in the case of my t2 its a bit noisier and a bit rougher. regards bri

It isn't.....as long as the light is ON then 4WD is still engaged, regardless of where the bleedin lever is!

Tomorrow is the test.I am near Wexford in Ireland.(Not sure if it was a good move yet)And we have been well and truly snowed in for a week.I did venture out on Monday and the old T2 behaved perfectly.It's all the numties in front wheel drive cars that are the real problem.
The roads are like skating rinks and here I am putering along in second or third 4wd when down the slope comes a Golf full on sideways.Talk about brown laning!Anyway managed to get out of his way by some miracle.Hope he could lip read.
Tomorrow we are off to town to get "supplies".You know the usual.
Coffee,flour ,beans and ammuniton for the Winchester !Should be an interesting trip as the roads are still pretty slippery.

after a week of being in 4wd, in both high and low, and low was needed when first vehicle
thru foot plus of snow field sorry road, such was resistance!

i work on idea that if main roads are slushy and will need 4 wd again soon on next side
road then keep in 4wd and try to help widen tracks thru slush by getting alteast one side
of car into slush then if any wind up little bit of slip will keep it at bay.

so when finally got to point didnt need at all and speed picked up was in 4 hi but car
felt little bit sluggish, it wa working harder, wasnt steering so didnt feel wind up that way,
flicked it in to 2wd on roll and was best described like when you realise handbrake was
on a notch or two. car then took off in 2wd as wasn't ever so slightly fighting itself.

front hubs remained locked so all front end was spinning upto transfer box, like fixed
hub cars and i reckon went in to 4wd easier when got to side roads again as box
didnt have to engage with front prop then 'excite' the auto hubs!
