@ Modded

Hey Modded, I also have this issue buit my vehicle is a 2011 Yukon with non air ride suspension. As soon as I did the 2/3 drop I got this light. Also I was so badly aligned in the front afterwards it was crazy!!

Hey so I do not have a solution for this yet. I was hoping that I would find an answer to this here. It seems like originally I was set up for a 2/3 but they sold me on the struts (which I added a 1/2" drop to the already 2" initial with the spindles) Rear shocks + springs that makes me Cali lean or maybe even level now!! WTF do I do??

I'm trying to avoid this issue on the front side. Just bought an 04 yukon and am looking to drop 2/3 on new ltz wheels. I was mcguaghys all the way but now am confused.

There is a plug right on the frame in the rear right next to the upper strut bolt. My socket loosened the plug and I had the same issue. Seems common I read allot about it here. Check that see if it's loose.this plug is the abs traction connector.

2007 Yukon 2WD history:
First Mod: 24" Rims: No problem.
Second: Bell Tech 2/3 drop WITHOUT spindles. Drove 3 years: no problem
Third: Install Kelderman Air Struts up front, drove 2 months: no problem
Fourth: Installed Bell Tech spindles (From Tony): ABS PROBLEM

I mentioned it to my alignment shop and he went through everything and checked all sensors. Didn't think to look it up on the forum, but here it is.

Tony, you know first hand my suspension history, any thoughts on how to fix?

 

[NORCAL SS]

on the 2007s this is apparent more then other vehicles. there was a TSB listed that addressed this issue. Changing to the belltech spindle cured it for one guys truck I did while other was a lot better than other spindle he had on there but from time to time would still kick on. I always wondered if there is something different with the BCM.

 

[LRob]

So it seems to go with the drop shock option rather than the spindle option to avoid the problem?

 

[NORCAL SS]

Yes or spring but camber kit will be needed. For autoride little different.

So I have an 07 z71 with a CCM 2.5/1 leveling kit. Also have 20 inch monsters with 305/55's. I am having the exact same problem with the brake pulsing when I make a slow speed right or left turn. It doesn't happen very often but is annoying when it does. Have anyone fixed this problem?

Add my truck to the list. Just installed a McGaughy 2/3 kit on my '07 Suburban today and I'm getting the traction control light flash, but no ABS pulsation. Happens with tighter, slow speed, left or right hand turns. Doesn't happen everytime, but probably 3/10 times. McGaughy kit is installed along with 22" CK375's that I installed last week. Didn't get the light until I dropped it today. Its nowhere near unbearable, but I'd like to find a solution. I was hoping to be among one of the lucky few that doesn't seem to have this problem after the drop, but it showed up the second I took it off the lift and pulled out of the bay...

Like Tony said.... it happens more on the early models. 2007 is early.

They must have programmed the stabilitrack different early on

 

[NORCAL SS]

its 2007 mostly

I am having this same issue now, just installed the Belltech 2 inch struts in the front and the 3-4 springs in the rear. Installed the front first then pulled out of the shop to turn around and install the rear with no lights. Installed the rear springs and immediately the stabilitrak, traction control and ABS light comes on. Yukon is sitting perfectly level now. This one is also a 2007.

 

[GalaxyBlackEsky]

Yours is a Denali correct? If so check your sensors to make sure they didn't get unpluged when lowering the rear axle.

 

[gmunee23]

Not a Denali, not auto ride either. I am going to inspect my sensors and wiring today.

 

[NORCAL SS]

your sensors popped off. IN rear if you DO NOT remove the lines from frame and put springs in 2 things can happen. 1 the sensor plug pops out or 2 you broke the line in rear and thats why the lights popped up.

I have the belltech kit 2/3,4 and I am getting an annoying clank clank noise from the rear.

Retorque everything

Check all brackets on the axle as well

 

[NORCAL SS]

Use both isolators on springs?

Tighten down extender bracket?

Hit me up if that doesnt work got a few other things you can check.
