4H in Snow

This is my first Wrangler and the dealer is telling me I wont need to put it into 4WD in the snow or heavy rain.

I know I will find out for myself and I can't wait but just thought I would see what your experience is with this.

Is 4WDH just used in Deep Snow or is 2 WD good enough in light snow (couple inches) because of large tires?

Thanks in Advance

I also heard that "spin outs" were a problem due to short wheel span. Is This True??

Thanks

If there is enough snow on the road to cause you to loose traction then you probably need 4wd. Last time it snowed here in GA while all the other cars were doing 15 mph I was crushing past them doing 45. Only time I've passed people on a regular basis.( yj 2.5 with 33's lol). Just be careful and you will feel it out.

As is with any rwd vehicle, a shorter wheel base will cause it to "spin out" easier. Be careful and drive slow and you will get the feel for it. I prefer the 4wd most of the time and pop it down to 2wd for turns to kick it out. Haha. I sure do hope we get some this year. :fingers crossed: good luck.

You won't need 4wd in rain. In snow it's a bit of trial and error, but my general rule of thumb is if there's enough snow that I can't see pavement, I'm in 4wd. Your tires are a big factor--snow tires are a huge leap from all seasons, and quality tires perform much better than crap tires (not to say there aren't quality tires for cheap though.) Just take your time until you have a good feel for how it handles.

This doesn't have anything to do with Jeeps. It's more of a 4WD vs 2WD trait. And I've found it to be true. 2 rear wheel drive with a short wheelbase will tend to spin faster & sooner than a longer wheel base rig. I believe they call it oversteer. 4WD or even front wheel drive cars tend to not do this (although FWD cars are known for understeer characteristics in the snow).

I have a 4x4 Avalanche that has an "Auto 4WD" feature. Pretty nice for those days when there is snow & dry pavement on the roads, which happens a LOT around here. The thing is so long that it goes sideways a lot slower than shorter trucks, which I find tends to make it a lot easier to control.

1. get a new dealer.

2. as noted above if there is snow covering the road, and its solid, not just a light dusting..then yes 4hi is a good idea. In some cases if its deep snow, you may need to switch to 4LO. I would not use 4wd hi if its just raining out.. now if its a monsoon and there is several inches of standing water then sure..

You will damage the jeep if you use 4H on pavement with turns. It's not AWD.

buddy tried that here recently, ended up losing his front driveshaft.

if your tires touch pavement, keep it in 2wd!

4H in jeeps the front and rear axle are locked together, always getting the same amount of torque. In short that means you need to be on lower traction surfaces that allow the tires to slip so that they can differentiate and the 'extra' torque doesn't cause drive train bind and start breaking things.

x3 if you see pavement you will break stuff in 4wd

Well, if your an idiot maybe. But I see your point.

I pull a 5k boat & trailer with my Avalanche. We launch on a deep sandy beach all the time..... in 4WD. If I don't put the truck in 2WD in the dirt, the drivetrain will bind up & stop as soon as I get to the concrete.

My brother had the same thing happen with him with a Subaru Outback. He had to put it in reverse & gas it good to unbind things so he could pull it out of 4WD. But nothing broke in either case.

I suppose if you hit the concrete in 4WD at speed, things would start breaking quick. The tires would certainly be barking like crazy.

Remember just because you can start out and go faster than most in 4wd, you still can't stop any better...

Thanks, this is all very helpful. Can't wait till it starts snowing. Sounds like it's going to be similar to my old Laredo. That thing was by far the best vehicle I've owned for snow including a Toyota 4x4 pick up and Mercedes ML 4 matic. The Wrangler should even be better than the Cherokee. Let it Snow!!!

If there's snow on the road then ours gets switched to 4H. We had lots of fun in the snow last winter, shortly after we purchased it and the first significant snowstorm in our area in years.

.... on dry pavement. If the wheels can slip, like on snow covered roads, then there is no binding on the drivetrain.
