I got stuck in the snow yesterday so I locked the front hubs and put it in 4 wheel drive. Only the front passenger and rear driver tires spin. The front driver tire will move just a bit when at higher RPMS and stop.
What and where should I look at first to get this corrected?
Thanks

That seems normal, the front and back have differentials, so if your front driver’s side tire has all the traction the passenger side front will spin, and it’s the same with the back axle. The only way to get all four to spin is to put differential lockers in it. Tire chains are a easier way to go for snow they give you more traction.
Though there is the slight chance you could have a brake sticking and it’s making this problem worse. |

As described, it sounds like your jeep is operating normally. I've done this same thing many times and this is where driver technique comes in.
Ideas I can offer is don't wait until you're stuck to select 4WD. Don't spin the tires if possible. Put weight (passengers) on the corners where spinning. Rock the vehicle forward and then backward to "get over the hump" - this has gotten me out of many spots. Put items under wheels (sticks, floor mats, chicken wire, cat litter, etc) to increase traction. Carry a shovel (long handle helps when reaching under vehicle). Bring a come along with some chain or a tow strap. Regardless of whether you have open diffs, chains or lockers, you can still get stuck even if you are paying attention. Carry survival gear also. Getting stuck is part of the learning curve.

The differentials give equal torque to each wheel. The spinning wheel has zero torque, and so will the non spinning wheel.

Thanks for the replies. I took the manilla rope off the front bumper and jammed it under the rear wheel and backed over it to get out. Worked like a charm. I seriously thought I had 4 wheel drive issues. Now I know better and I thank you all for the infromation and replies.

You can do the same thing with tire chains. I you get stuck with the chains off, jam one end under the tire and lay them out in the direction you want to go. Be careful, though, as you can spit them out from under the tire if you're not careful.

My dad always taught us that you put came go anywhere you want in 2wd drive and when you get stuck you put it in 4wd drive and get the heck out. Worked great for me in High School driving the jeep for 3 years. Just like you would think a 17 to 19 year old would drive his dads jeep when he wasn't looking. I only got stuck 3 times it took another vehicle to get me out. And those times it wouldn't have mattered if I had had a 6 wheel drive rig with big tires and lockers all around. I was in puddles of DEEP mud. And in a Snow filled ditch that had the jeep rocking on the skid plate with nothing but Mud and Snow to stir with the tires LOL.

This is the reason that "Lockers" are so commonly discussed in modern off-roading forums. Most modern rigs have either automatic lockers or air-lockers. These essentially defeat the differential to varying degrees. They will give you the ability to put power to all 4 wheels regardless of traction conditions. There are some negatives to lockers and you'll find many opinions on them. There are lockers available for the stock axles if you want to go that route.
Modern SUV's sometimes use the ABS speed sensors and the ECU to apply individual brakes in order to control wheel slippage. Probably better for most street driven cars. |

While browsing around the YouTube world, I found this little video that explains why all 4 wheels weren't turning.

Which is an absolutely idiotic way of dealing with it. Each momentary application of the brakes negatively impacts momentum. Whoever dreamed up that system should be flogged in the town square at high noon. Why they ever went away from limited slip differentials in favor of that junk is beyond me. My 2001 Ranger had limited slip diffs front and rear and when I say it could go anywhere, believe me it could go anywhere, and the best part is there's no computer involved, it's all mechanical. On the other hand my 4Runner has Traction & Stability Control. The first time it all kicked in and left me stuck halfway up a snowy hill I vowed to find a way around it and I did (but that's another story). |

A piece or two of old poly foam out of a old couch cushion can do wonders when stuck if you stuff it under or up against the wheels and will save your rope. Be sure and take the cover off of it and use just the foam itself. Recently saved my a## while slipping in some slick MS mud out in my pasture. Also helpful on ice or snow is a jug or so of kitty litter thrown in the back. You might be amazed at how much extra traction that will give you in a pinch if you sprinkle it around a bit.

Heh! I had to move my dad's 1969 International 1200 pickup after we had a 'winter storm'. We needed to move it from the concrete pad in front of the garage to a spot up beside the house. In 11 inches of snow. Moving it down the plowed gravel driveway was cake. It drops about 18 inches over ninety feet - a fairly gentle slope until you're trying to drag a 5000 pound truck with a locked front wheel back up to the house. I pulled it with the jeep in reverse, because I have a 3"x6"x5/16 channel iron front bumper with a draw-bar trailer ball mount, and the rear drawbar is completely missing. When I got to the snow beside the house the jeep just dug in. I didn't have enough traction to move the 'binder pickup, so I started trying to 'jerk' it by getting a run on the strap. That didn't seem like a really smart idea, and that's about the time I got stuck and my brother suggested the chains. We laid them out in the snow in front of the front tires and got enough traction to pull back on to the driveway - it was only a few feet. That's when I put the chains on the front tires. That gave me enough traction to tow the old International pickup into its parking spot through 11 inches of snow. We actually had quite a bit of fun doing it. I should probably mention that the pickup has a full size slide-in camper in the back. It ain't light. [edit] The jeep's brakes were out at the time too. Some genius used copper line to extend the brake line where the frame is stretched, and the exhaust pipe rubbed a hole in it..

It's not a great way of doing it, but it is effective at times. We used to do similar things, set the parking/e-brake a couple of clicks to put pressure on the wheels causing the power to split. Gotten my brother-in-law and myself out of a few tight spots. He even does it on some of the equipment we he's on a nasty job site.

That's the trick for driving military HMWVVs too - half a pedal of brake and mash the gas. It locks all four wheels in and the transmissions are so loose you hardly ever get wheel spin.
Heh. I laugh to myself when the HMWVVs in the movies lay rubber on pavement when the driver stomps on the gas. I promise you they don't do that. With the pedal on the firewall, they might hit 60 in five minutes.
