Abs/Traction Control/4wd help!

Hey, hope someone can help me figure out my issues.

I've got a 2011 Sr5 Tundra. I've owned it for almost 2 years and this issue started 8 months ago. I installed a leveling kit and 1" wheel spacers on the truck and have had nothing but issues since. It was a small kit only 3.5 inches in the front and 2 inches in the rear.

What's happening is this. When I first turn the truck on no lights are illuminated on the dash. I can engage 4wd hi or lo no issues. When I start moving the lights stay off up to 15 mph, the second I push over 15mph my abs/tc lights illuminate and my 4wd hi start blinking. If the vehicle was put in 4wd it will kick it out. After that the lights stay that way until the truck is parked and off. With a shutoff and restart the lights will all go away until that 15mph braket.

Under 15mph with no lights, the front driverside wheel area makes an odd grinding noise and the brake pedal will pulse when depressed.

I replaced the front drivers abs sensor and harness. The dealership originally thought that was an issue or the 4wd actuator. After fixing that sensor/harness nothing changed and still gave errors. I've had codes run on the ECM multiple times and it either says nothing is wrong or that my front abs and rear right abs sensors are bad.

I'm thinking of replacing the wheel bearings as those are stock and sounding a little rough.

Any ideas/help would be greatly appreciated!

 

My guess is that it's one of the other ABS sensors or the wiring leading from the main harness, to them. They're quite fragile and easily damaged, and likely were during the lift installation. The question is, which other one is it? I'd be most suspect of the ones that have thrown the codes.

 

My thoughts too, so thought the dealership as well. So I replaced the driverside sensor and harness. Same issue occurred. I found a wiring diagram here and the sensors aren't seeming to be daisy chained together
