4wd high bad?

i heard from a friend that driving in 4WD high is bad because like the front tires will spin faster than the rear, so he told me to always be in 4low when im using 4WD. is this true? what you guys thinkin

thanks!

Not really sure what you are asking. Your ratios don't change in your differentials between 4 hi and 4 low. It IS bad to drive in either 4 hi or 4 low on pavement. 4 low is just a lower ratio from your transfer case.

like jj said - there isn't a problem driving in either gear unless the differentials have different gear ratios.

4wd hi is for poor conditions (Snow, mud, slippery dirt, sand etc. where your wheels spin) up to 55mph.

4lo is not to exceed 25mph, same conditions as 4 hi

Um..............What? My guess is your friend never owned a 4x4. why would they (Chrysler) put a 4hi on the truck if you were not supposed to use it?

4lo and 4 hi function exactly the same, the front and rear wheels will spin at the same speed. Just don't use it on dry pavement.

what about partially snow covered roads. Driving in 4hi when its snowing but windy, so parts of the pavement may be dry, and parts are snow covered. DO you keep it in 2 or 4 hi?

All the years I lived up North I rarely ran in 4 hi or low during snow storms. I found the best way to drive on slick roads is to use 4x4 to get yourself moving then shift back into 2 and drive it like a rear wheel drive only shifting into 4 hi when absolutely needed.

Reasoning is simple...From my experience when you need to gain control of a rear wheel drive car simply let off the gas. For front wheel drive you would step on the gas. If you are running in 4 hi or low on slick roads then there is potential for going into a 4 wheel spin with no way to recover except a ditch.

And your friend sounds like he has never even seen a 4x4 let alone know how they work.

Just my .02

Stepping on the gas w/ a fwd car only works on dry, high traction surfaces such as pavement. If you step on the gas w/ a front wheel drive car on a slippery surface it will under steer or go with the level of the road, usually towards the ditch. That's why your jeep under steers when you drive it on slippery surfaces on 4hi and step on the gas. We just got ice/snow today so i'm fresh w/ that. At first it started as rain on a 25 degree pavement so it froze as a nice sheet of ice and then started snowing on top of that.

Been in New England driving snow/ice/slush covered roads for the better part of 25 years. Trip is right on about front drivers. My rule of thumb w/4x4 has always been if the road looks wet or slushy and the temp is below 32F leave it in 4hi, once the pavement starts to look dry go ack to 2hi. I've had 4x4 vehicles all my life and put many many miles on them this way and never had any issues w/breaking parts running this way.

I must be remember the one front wheel drive I owned incorrectly then. That was about 15 years ago and I haven't run OC's Acura on the Ice yet. I still drive with it in 4 wheel when needed here when we get winter ice storms and when that happens we usually get up to an inch of ice build up covered with a dusting of snow. Very glad it doesn't happen that often here.

sorry for the choppy post getting ready for work.
