Torque steer in 4 WD.

[(RIP) PLANK]

excuse me for sounding thick, but how do you 'feel' transmission wind up?

one thing I have noticed though when out in the mud or snow with new 4x4 drivers is the tendancy to grip the wheel far too tightly and not let the car just feel it's own way, rididing the ruts and bumps etc with enough pressure for control and correction, but not trying to grip it so it cant move at all.

I think what starts to happen, with a slightly nervous driver is the overcompensation for the feel of the terrain and it can make the vehicle a little unstable, like a constant preperation for miniature scandanavian flick

I am not suggesting this is the case here, but it might bear thinking about?

if i am completely wrong i apologise in advance :doh

I have allways found 30 psi all round works for me in a SWB T2 in a good mix of conditions towing and not, off road and on

I'd agree with Plank, I'm not sure you'd feel wind up on the straight - in a tight turn, or especially reversing in a turn, its very obvious though.

Tyre pressures, I thought the standard was 26psi or 1.8bar under normal?

Must check door sticker.....

PLANK no offence taken mucker but iam not new to 4WD,s. That is why I know the tranmission is winding up, if you had it on yours you would feel it straight away. When driving in the snow if i drove under a bridge say for example where there was no snow for say 40/50 feet I could feel it winding up, steering tightening up, feel the engine having work a little harder then back on snow you could feel one or two wheels spin (unwind) a bit immediatly. Some of the guys on here can come out of 4wd without stopping and reversing (4 wd high. ) I have to stop and reverse a bit to make mine release. Makes it awkward on times in the snowy conditions. Offroad its not a problem because you can do it before you get back on the tarmac. I know on the instructions it says to stop and reverse a meter but is this just to release the auto hubs or because the transmission is wound up a bit and you have to release it? After all its sellectable up to 25mph in a straight line. TEEBIRD

Tony I think with autohubs you can deselect 4W and drive with the hubs still engaged until you reverse and it shouldn't do any harm, cos theres no drive at the front diff when you've put the lever back to 2WD - at least thats what folk have surmised, I was always religious on my older truck and reversed every time.

The trucks that can deselect on the fly and see the light go out with no other action usually have fixed hubs - those let you engage 4WD at almost any speed (80mph in my case at the last try....).:augie

out of interest do you have a set of mathcing tyres with simmilar tread wear? or different front to back?

Good question Tony cos I still agree with him....I've done 250,000 miles or more in three of these trucks and driven a lot in 4WD in the wet and sometimes dry or just damp, and never detected windup.....but thats not to say some folks might, depends how sensitive your arse is I suppose LOL :lol:lol:lol:lol I mean you can feel if you're in 4WD or not, more so on some trucks than others - theres just 'more going on', but never had the transition you mention.

I'm wondering though, whether your LSD oil needs a change? They are known for misbehaving oddly when the oil is shagged....

 

[Teebird]

Plank, front tyres are 1/2 worn and the back are new. It was the same with the other back tyres on. Lacroupade, I have to reverse mine otherwise it will not release from 4wd. Yes I can see how that would work with fixed hubs, allspinning the same speed. My last 4x4 was a 3ltr diesel swb Landcruiser. You could select 4wd up to 60mph. I dont think i had to reverse it to dissengauge 4wd. (button on the dash) lever for 4wd low range (I think)

are there any members who live close to you? so you could try each others
t2's and compare?

I changed the diff oil about a month ago. Used castrol LSD specific oil. Maybe the diff is not working as it should. When I jacked each side off the floor before I could not turn the wheel by hand with the other side on the tarmac. Is this normal with lsd?

can never remember the correct answer to that one - common sense says yes you should be able to turn the wheel a bit, but only a tad, thats what LSD is about. but an eggspurt will tell us soon.....

 

[mobyone]

an lsd should provide all the drive to the wheel which is off of the ground. you need to be carefull as the rear wheels will drive to, take the rear prop off and then jack the front up and engage a gear with the aid of a helper, by the time the clutch starts to engage the wheel off the ground should be turning. if not, have you locked up the diff?
that is what should happen, but someone else may well tell you more definitely.
