|slangheld||Trying to save anyone some trouble. I know you can find this if you search for "High Oil Temp" or "aux trans cooler" or related topics, but I didn't find any of that until after I had problems. Just bought an 09 JKU Automatic. Found out that without an auxillary trans cooler on 07-11 JKU's, you are likely to overheat the trans in deep sand in 4H. With this setup, I now suggest 4L, O/D off, and air down to at least 15-20 psi.|

|jgorm||4H and bang gears like you are drag racing until you get to speed.|

|slangheld||Unfortunately, unless you have an aftermarket transmission cooler, you will be better off running in 4L in deep sand with your 07-11 JKU automatic. Design issues make it less about torque and speed, and more about preventing overheating. Also, make sure you switch off O/D.|

The sand in NC is about the closest place for us in Virginia to go 4wheeling. Plus, there is an entire neighborhood on the beach at Corolla, NC, and the only way to get to it is by 4wheeling over the beach, over the dunes and through miles of sandy, winding off road roads. The locals have made some baja trails back in the neighborhoods (btw I use that term loosely, there are not that many houses except very close to the beach) and they are a blast!
Plus, there are wild horses that live on the beaches, so it's nice if you like wildlife as well.

NC is starting to look like a sweet place to go on vacation. Nice beach

|castorj29||When driving in sand dunes. Always drive straight up or straight down the dunes.|

|Beachcomber||I have a stick also and use 4hi, first is fine but I have to wind it up because second will bog down if I don't. Last year it wasn't so bad but because it's so hot and dry this year the sand this year is like powder and everyone sinks leaving deep ruts.|

|lambdatoys||Guess it all depends on the texture of the sand. In Nag's Head, NC, the sand can be deep. If my jeep were an automatic I'd have no problem using 4hi, but since it's a stick and getting started is more difficult, 4low works much better.|

Oh Yeah the fine baby powder sand we have here is some scary stuff it just shifts out from under you and you start to slide went on some of those roads first day I got my Jeep didn't get too wild but even in 4low you have to be very carful.This was the same road a guy was driving his truck on going a little fast hit some of this soft sand on the road edge filpped his truck he went out the window and the truck rolled over him and he died.

But then other people are like, "They don't work at all! I hit 2 deer last year with them on my bumper!"
Both situations have the same outcome...with the deer whistles...their reliability depends on if you've hit a deer with them installed or not. With airing down, the answer depends on if you (or your friends) have gotten stuck or not without airing down. But the first time you get stuck, guess who will end up being right?

That must be what the sand dunes in china look like

|Jerry Bransford||For 31" tires, 30-31 psi is fine for the street. For the sand, I'd take 'em down to 13.|

Sweet ride man!

Imperial Sand Dunes, CA. 3PSI rear, 4PSI front. 2wd only, never needed 4WD. Wheel speed and momentum are your friends.

4low works like a dream through even the thickest sand with a 4cyl

|coolbreeze||A long time ago we ran 1100X15 farm implement tires at low pressure in the sand. (kind of looked like airplane tires) Traction tires aren't the best for deep sand. Have fun.|

|Beachcomber||I drive in the sand all the time. I have 31x10.50 which I keep at 32lbs on the road and air down to 18lbs in the sand. The sand does slow you down. When the sand is real dry and deep, shifting to second gear is like putting on the brakes for a few seconds. I try to do my shifting when the sand isn't to deep or when in someone elses tire tracks. Last weekend I aired down and got half way to the water when I just started digging in, then I saw I forgot to get into 4wd. If I didn't air down I would have been in real trouble.|

I will either be THE IDIOT on the 6o'clock news in that scenario, OR
the chick at the edge too scared to drive past the high tide line.
Just kidding. Thanks for the advice!! I need all I can get when it comes to off-road stuff.
|07-22-2010 06:18 PM|
|jeepjones||Watch out for the wet soupy type of sand, it'll suck you in and it doesn't let go. Scary when the tide is starting to come in.|

What? I thought she could handle that! She IS a Jeep after all!
Still cleaning up my pepsi....

[QUOTE=TjTheo;697691]Well first of all, there's no way you can drive on sand upside down, that's a no no.
I just busted out laughing and spit my pepsi all over my computer. Thanks a lot! Now I have to clean it!
I have nothing to contribute to this conversation, but learned alot from Jerry, et. al. I am planning my first sand ride in my TJ soon, and this gave me some good information. Thanks so much, guys!
Oh, and BTW...don't feel bad. I can't get my pics to show up right on the forum, either!

Btw Lethaljeep you put your rig in 4low in sand? Maybe I'm doing it wrong, I always use 4high for sand and 4low for steep rocky inclines.
