    Default Using 4H in the Rain on Tar

    Good Morning and a Happy new year to all. Haha. Viva.

    I have a 2010 Navara KingCab and in yesterdays rain I was slipping and sliding on Nothcliff Hill on my way home. Which made me think if I would I be able to use 4H on Tar roads like I know you can in a triton without damaging the 4x4 drive system.

    Has anyone done this? Any advice will be greatly appreciated.

    Thank you and enjoy the rest of your day.

    Maybe I misunderstand, but if you slipping and sliding downhill in a car with ABS I doubt 4x4 is going to help?

    Only the 2.5 Triton with super select as this has a permanent 4x4 option without the limited slip centre diff being locked. The Navara is a part time 4x4 and this is not advisable.

    Just slow down.

    I've often run 4H with centre diff lock on in heavy rains.

    Big trick is to make sure you disengage it if you intend to do a sharp turn, or the road is drying.

    definitely helps. but it can bite you.

    Northcliff hill has very steep windy roads.
    I suspect his wheels were spinning as he was going uphill.
    ABS works when you are braking, but doesn't help when spinning.

    I have a work bakkie - KB300D-Teq Single Cab.
    Lots of power, no weight on the rear wheels.
    In the rain a year ago I was struggling to get up Northcliff hill.
    This despite the tar being quite rough.
    I suppose tyres at 2.8bar & no load was not helping.
    I put the difflock on to get up one steep section.
    But as the roads are windy I only used it for a few meters at a time.

    I think that the OP could well use 4H to get the front wheels to help.
    But he should not use the difflock.
    Obviously, being tar, he should return to 2H once he is off the steep slippy bits.

    On my Pajero Sport there is a note that says never engage 4H in a paved surface.

    Good Morning All. Thank you for your comments. Yes it is the uphill sections where I struggle sometimes. I also suspect my tyres are not the best in the rain. I got the Bakkie with Dunlop AT. I am partial to bridgestone dueler AT and as such believe the problem will be reduced when I get some new takkies. Thank you guys again. Enjoy the rest of your day.

    As mentioned above - it is safe to engage 4x4 with the transfer case locked as long as there is slip on the wheels, and as long as you are not turning.
    In hard rain or slippery road surfaces this is the case.
    But make very sure you disengage before the grip gets too much or before you have to turn - if you try to disengage the transfer case while you have ample grip, or while in a turn, it might not disengage due to the stresses on the system.
    The best 4x4 is an Avis Polo

    It will activate the 4H when the rears lose traction and disengage automatically when not needed

    It sounds to me like this is the actual problem.

    Isn't Auto only on the Pathfinders?

    Good Morning. Yes I definitely do not have an auto option on the 4x4 selector. My tyres are yokohama geolander at. With lots of tread on them. Some say they are good in the wet. But it does not seem to be the case with me as they slip even on lever wet Tar when the turbo kicks in. Name:  uploadfromtaptalk1452586004823.jpg

    Are your tires not perhaps inflated a bit hard?
    Try deflating them a bit to say 2bar/1.8bar - see if it helps. Same logic as with sand etc.
