4x4 on dry pavement,Not!

[tillery444]

The question comes up quite often about using 4x4 in dry pavement, I found this link on the Yota forum on why not to!

LOL how do you not notice you truck is in 4wd for 150 miles???

hey the titan is my 1st 4x4 vehicle one reason I purchased it 4x4 was for safety like when is raining real bad or ice on the road, does this mean I should not used the hi4x4 on this conditions... ?

the other main reason is too off road

Great Info Tillery. I think this should be a sticky!! I will submit it to one of the mods and see if we can get it as a sticky.

DOva-raining real bad-no! 4WD does not stop hydroplaning so slowing down is the best way to manage that. Same is true for ice.

A locked differential will be supplying power to both wheels meaning if one slips, both are spinning and still not giving you the traction.

Snow, mud, sand are conditions for 4WD.

Your VDC (Vehicle Dynamic Control) is a good device for preventing slippage-in rain/snow so leave it on! The system is there to help keep you on your steered path. If your Titan should start to oversteer (fishtail) or understeer (plow forward), VDC will reduce engine power and/or apply braking pressure to specific wheels to help keep you on course.

4-wheel Limited Slip (ABLS) applies braking force to a wheel that's losing traction while directing power to the wheels with a better grip.

Those two systems are your best bet when managing ice/rain. If you are on ice 4WD will help ONLY IF you reduce speed and prevent tires from losing traction.

thanks for that info
not sure about LOL

I am proud to contribute to public safety by wearing rain grooves in the road with my studded snow tires to prevent others from hydroplaning.

DOva what Kronos is saying is NO don't use 4wd on the wet or dry pavement. Some snowy/ice conditions yes, mud yes, sandy roads yes. NOT ON ASPHALT. If you do you will break something eventually.

Some Jeeps have a full time 4wd that allows you to stay on 4wd all the time. My Grand CH had it and it was great.

Well I use mine on pavement every so often, just to engauge and disengauge it if I have not been offroad. I try to go in a straight line as well (not make turns when I do this). Guess I won't do it anymore....But I can't say i will totaly stop, every so often I may cross a paved road while offroading :P

I agree, on this one. If I'm on the interstate, below the rated speed, I will engage 4 hi for 5 - 10 mi. In NO way would I ever drive in/ arround town with 4 engaged, or for long periods on pavement...... I use my truck for mostly getting fire wood in places I don't want to get stuck.... I Have done this on occasion, about every 3-4 mo when I haven't been off roading in a while.

I have worked on USAF C-130s for 22 years as an allison/ rolls-royce engine mech. One thing I have learned is that if it isn't used it breaks. I understand the whole bind/ wrap/ pinch..... I like to make sure that its a nice straight stretch.

And just to piggyback on the shatted front diff post, I will attach a rope/ tow strap to the rear receiver (with my SO seated with it in 4 low and foot off of the brake and maybe slight throttle) when Im cutting a tree in a tight area, to ensure it falls in the right direction!
My .02 on this one........

Hate to tell an aircraft mechanic this but, that wasn't a front diff that was a transfer case. That is what takes most of the stress from this kind of abuse (4x4 dry). Also another reason some four wheeler and drag racers use small u joints. They work like fuses and sre much cheaper to replace than axles and transfer cases. Just remember when servicing your truck always check for a loose nut behind the steering wheel. Fixing that helps prevent serious damage to your truck!

Really? I thought you should be at a pretty slow speed to engage 4x4. You must be going 50-60 when you're engaging 4 wheel drive. Is that safe?

[Lurchdubious]

the problem that i run into is that on the residential roads around my house the streets are covered in snow, then i go on a main road it will have been salted & completely dry, with some icy patches here & there. if i'm only gonna be on the main road for a couple blocks, i'll leave it in 4x4 just to avoid constantly switching back & forth. should i leave it, or switch all the time?

People always think 4x4 stops them from crashing, not!

My dad's jeep has the option of 4wd part time where it only kicks in when you need it.
