09 yukon harsh drive and traction control error message

Hello all,

Last month I replaced the front upper control arm left and right, sway bar links, both hub bearings, outer tie rods, rebuild the rack and pinion, driver side engine mount, new michelin tyres with alignments (tyres and road alignment) and finally the rear left airride suspension. Sound good? Felt good at the time, however after everything done just before the rear suspension and the engine mount I’ve got traction control light on with traction and stability control service message i did not think it would effect the driving and honestly I thought the steering position sensor is out and since they don’t have it anymore anywhere, just to note when I start the car no error come except when I turn the wheel right all the way or drive a little bet but no message pop up when I turn it left of course it comes on eventually as am driving little more, but couple of days ago I found out that if some how I drove it for short distance and turning only left it become very harsh and the left side bounce in the same time the traction triangle light start flashing rapidly, I don’t have access for any gm code reader and I would appreciate any help or ideas what it could be or where to start


Cruise control work so that check for the brake switch.

check out a video I made for my car when it does that

Looks to me like it's behaving like it's either in 4wd mode or you have something wrong with the left front hub, despite that you replaced it. Best to get that thing up in the air to have a look.

It was on the 2wd mode thats out of discussion I guess, but it came to me that it could be the hub’s speed sensor but usually it illuminates both ABS and traction errors signs, or it doesn’t?

They can get stuck in 4wd mode if the actuator isn't working. Given the jerking, it looks like more than just the speed sensor. And the speed sensor can fail if the hub bearing is failing.

I hate aftermarket parts which the hubs are, I went off-roading and it switched between 2wd, 4h & 4L but I will double check.

Should I replace the new hub’s speed sensor with the genuine old sensor from the old hub? Never had an issue with the old one
