    Can it harm if i drive my blazer K5 in 4wd on wet pavement?

    It`s snowing in Amsterdam now and some parts off the road are slippery and some parts are not, now i have to slowdown every time i shift from 2wd to 4wd.
    Hope somebodey can give me advise about this.

    A happy new year to you all.

    I've run in 4WD in heavy rain before. It really helps keep the truck from jumping around when just one or two tires hydroplane. The water also provides enough tire slip to keep the driveline from binding.

    As for "slowdown every time i shift from 2wd to 4wd", try shifting at speed. As long as the front hubs remain locked it should shift easily. Everything is already spinning so all you need to do is engage or disengage the gear. I do it all the time with mine.

    You can shift in and out of 2 hi to 4 hi or 4 hi to 2 hi at any speed up to 55 mph according to my owners manual. I do all the time with no problems.I just let up on the gas when I shift I have about the same setup as yours xcept mines a 89

    do you leave it in drive,and slam it into 4wd? or neutral? I never heard of doing that!

    If it ain't a Chevy, don't raise it up!

    On the 208 you can shift on the fly(in drive and, of course, with auto hubs). I dont have a manual, but I have a brochure for a '84 and it says to shift under speeds of 25.

    When my hubs are locked I shift mine between 4HI and 2HI at speed and in gear, and I have a NP 205. I do take my foot off the gas though. As HarryH3 has pointed out when the hubs are engaged everything is turning at the same speed, all you're doing is engaging the front wheels. Going into LOW range is another story, I stop completely, depress the clutch and then shift into LOW range.

    Unless you have an NP203 with full-time 4wd, I'd rather stay in 2wd on wet pavement. It probably wouldn't damage anything, but in 4wd at least one wheel could lose traction on curves, or would make you go straight, which could cause an accident.

    I also live in the Netherlands. Let me tell you this, do not drive in 4WD in this country. Our roads have a far more agressive grip on your tires. Unless you have a full time 4WD you will end up with damage.

    Thank you all for the reposts and HAPPY NEW YEAR TO YOU ALL.

    When i understand it right. I can drive on a snowy wet road in 4WD. And when it`s a dry road i shift on the fly from 2WD to 4WD when i hit snow.

    Hey River,

    Was checking out your website (thinking it was about your K-5)... what is this about? Do you travel around by cycle? Do you run a camp sight for those who do?

    Just curious.
