Replacement rear diff carrier?

Hey Sal,

I thought the traction control and esp turned off in 4 low completely? And you can manually disable it in 4 hi with the button press for 5 seconds? The elsd works in 4 low straight off the wheel speed sensors?

No you cannot turn off the traction controll system completely. We have a chart here somewhere that shows the different settings but I'm on my phone so I'll try finding it later. I think maybe the ESP can go full off. In the different modes different options get shut down. Like one setting kills the part that kills power during wheel slip but keeps the brake torque part active. The only way to completely shut down the abs is to disable it. I'll look for the chart when I get home if know one finds it first. Of course it changes between drive systems.

^Correct. The traction control stays on while in 4 low. Otherwise it would be a useless system since we have no locking ability (except for LSD option on QDII). The Rollover/Skid protection part turns off in 4 low but without traction control we'd be stuck. My brakes get squeaky when i'm going slow and am in a dusty atmosphere so i hear everytime the traction control kicks in (even if it's a minor correction) i heard it plenty while at Big bend in certain hill climbing situations and going over heavily rocked terrain. Never needed 4 low though on that trip.

Should have said I have QDII. To me it feels as if the Traction control is off in 4 low, the light is on and there is no feel of braking to the wheels when crawling 2 wheels off the ground. The ABS does stay on, thats permanent. Unless you get mud in the sensor plug.....another story.

Id love to see that chart Sal.

QD2 in 4 low I think operates with the clutch packs not with the brakes so you're correct. I think???? LMAO let me find that chart

[Sal-XK]

I can't find and can't remember who posted it I think it might have been Don. Hopefully someones memory will get jarred and know where it is. I'll keep looking though.

Been searching, no luck yet. But if the TCS was still even partially operational in 4low this wouldnt be possible...

Don sent me some links I'll check them out when I get a chance. I'm pretty sure in 4LO QD2 it's all the elsd doing all the work no brakes or anything.
