Quadra-Trac I is designed for Jeep Grand Cherokee owners who want the assurance of full-time all-wheel drive and no switches or levers to pull, the Quadra-Trac I is the right system. The system provides for smooth operation of the vehicle over a variety of road surface conditions. No driver interaction is required.
The NV140 transfer case splits torque 48/52 percent (front/rear) for nearly even distribution of engine power. The single-speed transfer case has been designed to rigorous Jeep durability standards while offering smooth and quiet operation. The use of Brake Traction Control System (BTCS) with the NV140 transfer case makes the 4 x 4 system extremely competent in a variety of situations. The BTC system provides resistance to any wheel that is slipping to allow additional torque transfer to wheels with traction.
Offering a single-speed transfer case attracts a new group of buyers to the Jeep Grand Cherokee lineup and builds on the capable, entry-level, two-wheel drive versions, which currently account for approximately 25 percent of Jeep vehicle sales.
so IMO: NO it should NOT be driven on sand. You got one drive wheel per axle. no lo gear. no sand driving.
You can drive in sand, you just need to deflate your tires to approx 15 psi. If you dont, then there is a greater chance you will get stuck and you will most likely over heat either the tranny and/or motor.
But use common sense. Dont go in the dunes, stay where the sand is hard or other there are other tire tracks.
I have taken my jeep out on the beach in the outer banks. Never had a problem and i'm 3.7L with QT1.
Dude dude dude!!!!! woah woah woah on the lowering your tire pressure!!! 15psi is ALOT!!!!
plain and simple, the QT1 isnt made for the sand. Therefore, dont try to break it in. Its a 2010 jeep, with the 3.7. Rob has posted great info, and reasoning as to why not to do it.
imo dont do it, and DONT lower your tire pressure 15 psi lower then the regular psi
I don't think you would have much trouble driving on sand as long as you air down your tires and try to stay on paths that are traveled frequently. Awd can get you to most places 4wd can, you just have to be very careful how you approach the scenarios.
Actually klutch, 15-20psi is about right. If you are on the sand you want to lower the air pressure on your tires to a fairly low psi to give you more foot print on rocks, sand, deep snow. etc. . You'll be fine as long as your not driving fast/gunning it/turning super hard and fast. Then the bead will pop off and that would be bad mmk. There is a limit on how far down you can go per terrain. IMO if you don't have onboard air... i wouldn't even bother.
You'll be fine in sand either way. AWD system is more than enough. A 4x2 would be fine out on the beach even... long as you don't floor it and do stupid things
I've driven mine many times on the beaches of the Outer Banks....through deep soft sand...never been stuck. You will be fine. Air down to around 20 I'd say, and keep the momentum going in the soft stuff. The guys claiming QT1 isn't made for sand don't have QT1, so they have no real life experience using a WK with QT1 on sand. Take their advice and you'll miss out on the fun your WK is capable of giving you.
You want some good advice? Get tow hooks and a recovery strap before you go...and if possible, go with another vehicle, so if you do get stuck, you can get a tug out, but imo, you'll be fine and there is no reason to keep it on the pavement because you don't have 4lo.
Have it suck down to its frame then you can really see were mud can end up. I remember draining out my trans case in my ZJ and seeing a clump of dirt a year or so after I had it stuck :lol:
You will be fine. At the most you might want to air down to 15 psi if you will be doing this for long extended periods of time/miles. Then carefully drive to a gas station to air up. But that will set off the tire pressure warning system. I used to run 10 psi with my Xj when wheeling and some times had to go 20 mins to a gas station just driving carefully.
BUT the Wk has very wide tires for stock tires so if its just some, drive on, drive around, park etc stuff you should be 100% fine just the way it is. Just steer clear of the water. Salt Water and salty sand water is a bad idea.
Yes, as I have mentioned before. You should air down to 15-20. Of course when you are done, drive slowly to your nearby gas station and fill back up. As for the QT2 and QD owners who have chimed in. You should still air down regardless. Sure you'll probably be fine without airing down. And should you get stuck without airing down, then get out your car and air down to 15psi where you are stuck before you dig yourself deeper.
have QD2, and have been on the beaches of SPI 3-4 times, never aired down, jeep never bogged down once. And this was going into some really soft sand :thumbsup:
Driving conditions on SPI are highly variable. At low tide you can drive all the way to Mansfield Pass in a 2WD vehicle, especially if there has been recent rain. At high tide, you are forced to drive in deep sand and debris, I wouldn't do it in QD1.
