oh crap whats that noise

The brake traction control activation is never turned off. When you turn ESP off its different levels of throttle control that are eliminated; such as wheel spin when accelerating and throttle cutoff when sliding sideways.

Unless you have a switch to the ABS pump fuse like I have :0)

Which doesn't do anyone any good unless they have lockers like you do or want 1 wheel peel offroad

Just went for a spin and heard the noise too! Interesting i've never heard that before... but I can't remember the last time my Jeep sat outside in that cold, and I normally don't hit the gas that hard to accelerate.

Will have to see if it does it tomorrow morning after sitting in the garage all night.

Has to be something a long the lines of ice melting off bottom engine while driving and when you stop it drips on some of the suspension/drivetrain and freezes. I never really heard anything like that, except making turns which is the ESP, mainly cause of my exhaust being loud. I always cleaned underneath it though like every 2-3 days, max! Id say everyone take it to the wash and spray the underside thoroughly and see what happens. Salt is some nasty **** especially mixed with snow, ice, dirt, oil etc..

[Matt]

Yeah it's gotta be ice built up somewhere. Any deposits will melt off tonight in the garage and I'll see if it does tomorrow night after it sits outside for 13+ hours without any source for ice.

It sounds nothing like ESP kicking in btw.

Hmmm from what I've read, it sounds like traction control/ESP but maybe I'm just understanding wrong. As far as turning it off...traction control and ESP are ALWAYS on to some degree at low speeds. Holding it turns it mostly off but there are times when it will still kick in. And of course it goes back to partially off above 45 MPH I think. So like Adam said, only way to completely get rid of it is to rig up a switch like his. You should see what it's like turning off TC/ESP on my mom's ML320 CDI...the button does basically nothing at all to turn it off.

It's -5 out where I live and my jeep isn't making the noise you guys are talking about. I feel left out lol

[johnr]

please don't feel left out is is not a nice sound.
So as far as the ice build up theory goes im not sold. my drive to and from work is only about 4 miles each way. but giving the theory a chance I though id try to break it loose before I left work today. before I pulled out of the parking lot I held the brake and put it in gear and torqued up the mounts forward and back and let it roll a bit then hit the brakes hard to flex off any ice. I left the parking lot and once I was straight on the road, accelerated and there it was again. sounds just like im feeding an ice crusher to make a slushy. by the time I get to my street it usually will not do it anymore but there is a nice icy patch in front of the house. so just to hear the sound of the track control is stopped and jumped on it a bit, that is defenatly a different sound.

^^That's kind of what I was planning on testing out tomorrow.

Yesterday i was driving through snow and some deep plow piles for fun, so I know i had a lot of snow packed under my engine that could have melted and turned to ice chunks. Being in my garage tonight that'll ALL be gone and i was going to see if the noise comes back after not having any snow/ice in the drivetrain.
