.....also Pete....not a good idea to engage 4WD on a paved surface at any time let alone for several kms (straight road or not)....this again is talked about in your handbook.

Ditto all the above. I know we blokes do it as a last resort but do read the manual, it is even more important these days. 4wd should never be engaged on bitumen.

thanks for the prompt reply i shall take another look at the manual. I did read the manual, however from memory it said something like ... dont use constant (full time) 4wd on paved surface as it will give a lot of wear on the drive train. anyhow thanks for the input. appreciate it. cheers

Pete constant or full time 4WD have a centre differential and these babies are designed to operate as the name suggest ie full time.....now if you lock the centre diff that is another story all together....and if you do this on paved surfaces stand by for some lightening of your wallet if the drive train winds up a little too far.

All Rodeos I have seen from that year have selectable 2H, 4H, 4L, that is they are part time 4wd, not constant 4wd. But anyway, I'll let you check the manual. If it is part time 4wd as I suspect, then you should not engage 4wd on grippy surfaces like bitumen and concrete. This is because the front and rear axles will not turn at exactly the same revs (for many reasons) and since they are coupled together by the transfer case, if a wheel can not slip on the ground then something mechanical has to give- which it will eventually do in spectacular and expensive fashion.


- btw constant 4wd is a misnomer if ever there was one. No vehicle that actually has both axles driving 100% of the time could avoid the nasty scenario above. Constant 4WDs are not "hard coupled" in the transfer case, they have a centre differential that allows slip and thus are not truly constant 4wd at all.- unless you engage the centre diff lock. If you are keen to understand this better, I thoroughly recommend doing a search of your local area for a good 4wd training course.

Kind regards

David-going by that description of yours about constant 4wd-then there is no such thing as 2 wheel drive either.
Then even with centre diff lock engaged its not "4wd" as youve described unless it has 2 difflocks.
Its only really a description for ease and probably just complicates things for a beginner to describe it that way.

:-)

True but my point is that a full time 4wd does not have both axles driven 100% of the time, regardless of the number of wheels driven, whereas a part time 4wd does have both axles driven when in "4wd". So the full time four wheel drive is less 4wd than the part time 4wd, unless the centre diff is locked in which case it is equal....go figure. Now if that doesn't confuse some, I'll eat my hat :-)

yes :-)

but unless part time 4wd has difflocks, neither is it driving all wheels at the same time, all the time!

Pedantic lesson finished on my part!

:-)

Yes but being even more of a pedant, the full time 4wd's worst performance "in constant 4wd" is one wheel drive whereas the part time 4wd's worst performance is 2wd :-)

with 4wd engaged - i meant to finish. Yes pedantic for sure but many a Prado owner have I assisted who was bogged, and told me incredulously, he couldn't understand why he needed to lock the centre diff, as "it is full time 4wd" :-)

"full time 4wd's worst performance "in constant 4wd" is one wheel drive whereas the part time 4wd's worst performance is 2wd :-)"

:-) HOWEVER-if your can has only 1 wheel on the ground-you are in the s++t!
There are always going to be 2 wheels on the ground at least and whether part time or full time you are still clucked without a difflock in that situation!

gotta laugh though-I enjoy reading your posts, as they are among the more informative!

Thanks fisho....just having a bit of fun and hoping it causes a few to think and investigate. All in good fun

Cheers

HI Guys, i have seen a 4wd that was left in 4wd and had just come off a 110klm zone on the sunshine coast, i was only 18, and it scared tehcrap out of me, front wheels spinning in reverse, back wheels pushing forward.

so please check and double check you haven't locked anything up incorrectly.

Oh a word of wisdom, READ THE MANUAL.

I do and get a lot of praise from the other HALF as she doesn't bother, not when she has me who has read the manual,.

Sometimes as well as the back off on power, it takes a push of the clutch as well.

Its all in the owners manual - Wait until you start doing the low range work - you will have fun getting it in and out if you do not do as the manual says.

To go in to low 4, Stop and out of gear with foot off clutch before selecting. To get out Stop, out of gear and push button, if it still flashes quickly push the button again, when flashing slowly reverse the car a bit.

Its all fun until you get the hang of it. Cheers Tony

You may well be right Tony. I have an auto so no "clutch" to think about.
