Aww crap. I hit some nasty sand few weeks back and my Rubi was shaking and chattering and what not. I thought that was normal lololol

Sorry, new to offroad and jeeping. So this SHOULDNT happen? Do I need to bring it in? I believe I was in 4H not 4L
This is exactly why I have my lockers wired to my aux switches, I lock front and rear in 4 h and go through sand like driving down a dirt road. If lockers are engaged then traction control doesn’t come on because there’s no independent wheel slipping so it doesn’t apply brakes.....:)

I tried it again yesterday, it does that when you're in low rpms and the traction control is a bitch, anyways i assume you have the 4 position transfer case, what i found worked is,

On a flat soft sand surface
4high or 4auto if you have the 5 position transfer case, keep it in 2nd and just take it easy if it starts to bog floor it, if it starts shaking and doing that then stop and shift into 4low keep it in 2nd and keep the rpms below 1500 it will crawl out more like inch out, if it shakes and chatters you are pressing the accelerator too far and ur rpms is too high.

On an incline
Use 4high and use 2nd or 3rd and keep your rpms over 3000 the higher the better and if u feel it slow down floor it, it might shudder or chatter a bit just keep in it unless you slow down to a near stop or you think you will break something, Reverse and try again with more momentum youre more likely to break something while its doing that if you do get stuck near the top and u dont feel like trying again shift into 4low with both lockers locked and put it into 1st or 2nd and just give it a little gas the rpm will atutter while the car looks for traction like in the video above you can floor it but your jeep with start to shake once ur rpm go too high it best to just keep it in low rpm and just like rock crawling inch bit by bit till you find enough traction

Also never forget to lower your tires down to 15psi orower and when your on sand using 4auto or 4high just push the traction button for 6 seconds till u see esp off, i didnt really see a difference on the sand tbh i just turn it off, I just do it since every car and the jk needed you to do that.

do we know if it's traction control or brake lock differential (BLD) that's causing the issue? the long press on the traction control button disables traction control but BLD is always active as far as I know. did the JK have BLD?

Can you explain a little more? So you dont have the switch in the red color panel for the lockers? You use one of your 4 aux for lockers?

Lockers in this situation would be good? I thought traction control could be turned off?

I do have that switch still, I just don’t use it. I have Mopar wiring harnesses that plug into the front/rear differentials and I wired them to my auxiliary switches 3&4, ( 3 front & 4 rear to help me remember, lol.) You can turn off traction control by holding button for however long it says to, but as long as your connected to the computer bld (brake lock differential) is always going to be active because it uses the ABS system. With my harnesses I bypass the computer, it doesn’t know what I’m doing, as far as it knows I don’t have locker engaged, when in fact I do. The bld works with abs when one wheel slips it slows it down to transfer torque to the wheel that’s not slipping. When lockers are engaged you don’t have independent wheel slippage therefore bld doesn’t engage....:)

Yeah, I have tazer mini, it does all that for sure, but when I use it for lockers it hesitates, sometimes it goes right on but sometimes it can take almost a minute before it locks. It might just be my tazer, I’m not saying they all do this but for me I like the instant on, instant off especially if I’m navigating a spot where I need to turn front on or off while maneuvering....:)
Yeah pretty sure since the Tazer is instructing the computer to do the engagement the computer is doing all the sensor checks and whatever else before it goes ahead and locks things up. I would think on sand going straight that it would do it pretty quick. For me engagement seems to go pretty fast, disengage usually takes longer. Direct wire is certainly going to be faster.

Tazer is just less work and less intrusive and also gives you lots of other functions (TC Kill). I would recommend Tazer first and if they desire the instant locker that come with direct wiring over the Tazer then add that on afterwards.

so bld works when there is independent wheel slippage, when the lockers are engaged using the aux switches to bypass the computer that wont happen therefore bld wont come on ?, so i can drive in 4h and 2h with with the lockers on and the bld off ?

if so, will the lockers show as engaged on my dash or my off road page ? will the red buttons still work as they should ? and one final question is how will it drive in 4auto ?

sorry lots of questions, i just prefer this over the Tazer JL since our laws and dealership are not the same.

Ok.... if you have lockers wired to aux switches then you can no longer use the factory switch. Nothing will come on anywhere on the dash or off-road pages telling you that lockers are engaged or not. This is what turns some people off from doing this. But I can tell when I’m locked and unlocked by the way it drives. Also if you listen you can here the click. Bld won’t engage because when you’re locked up then you don’t have individual wheel slippage. You can use front and rear lockers in 4 hi and drive as fast as you want they won’t disengage, you can also use rear lockers only in 2 hi. 4 auto is not available with lockers, at least here in the states, so I can’t answer the last question. Hope this makes sense....:whew:

thank you, there is a little orange light i mean there is always that. if i want to reverse it i just remover the plug to the aux switches and plug in the factory one to get the factory switch back ?

Traction control is gimmicky it may work about 25% of time but other times like in the dunes you want to have full control so turn it off and avoid a computer attempting to deal with the sand. Momentum is your friend in sand.
I was thinking the same thing. There is a TC on/off button on the center stack. In my one, and only up until now off roading experience I found it much better to turn the traction control off.

Yes.. I just got a rubber cap and taped it up and zip tied it up out of the way and all you do if you want to use factory switch is just plug factory harness back in. Here’s pictures of how I ran wire to front differential up by where hood meets cowl and picture of my factory plugged in and Mopar capped off.

I was doing REALLY deep sand the other week in my JLU Sport. Aired down to 15psi and was in 4H, didn't turn off traction control. No issues whatsoever. We're talking deep sand around dunes and stuff way far back from the packed stuff near the water.

Someone else said it earlier, but if you're gonna be in non-packed sand, air down.

Default mode: 4H traction control tries to keep both axles spinning the same speed and if it detects the wheels are spinning much faster than the vehicle is moving it uses braking and torque control (cuts power and feels like its bogging down)
Brake lock differential mode works all the time in 4L or 4H even if TC button is pushed/turned off.
With lockers, BLD should not activate because both wheels are always spinning the same speed and would not trigger it to come on. I wouldn't lock front axle unless you're not turning and you need it to get unstuck......it will be hard to turn and forcing it is hard on the front U joints. With the front locker off you still would have BLD as needed when detected and is less stress on u joints.

When driving in deep snow or sand where you need to keep momentum.....push the button/turn off TC in 4H. (4L TC is off all the time but BLD is always on) The engine will not cut power, and brake lock Diff mode will try to apply braking to a tire thats spinning faster than the other tire on that same axle. With TC off in 4H the system does not try to cut power if one axle is spinning too fast or faster than the other axle.
