Stability off message appears, restart car and disappears ,then returns , recently had front wheel bearingd replaced?

This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS module returns the solenoid valves to their normal position and normal (base) braking resumes. OBDII Code C1155 Ford - Left Front Wheel Speed ...

The bolts that are holding the cover are loosing enough to allow the plate to move have the plate reset and the bolts installed with lock tie.

sounds like wheel bearing, jack wheel up, an see if there is any free play, by trying to move wheel side to side

Have codes checked

when removing the wheel bearing it is common to mistakenly brake the ABS sensor, or not have it seated all the way and it isnt picking up a signal. Who replaced the wheel bearing?

You have a broken wiring harness to one of the front wheel sensors. This is a very common problem. You'll have to have the abs codes read to know which side, and then you can either repair or replace that piece. As the front wheels swing back and forth as you steer, the wires leading out of the fender well to the wheel hub fatigue and break inside the insulation, making it almost impossible to see from the outside where the break is. If you have an ohmmeter and are handy with tools, you can check each front harness for contnuity while wiggling it. This is a little tricky, but it will work if you can't find a way to read the codes.

noises are a pig to diagnose from afar but i would get a can of spray silicon and spray one component at a time to find the noise...do it when dry and when you dont hear it guess what?.....

Hi vibration at 60 is normally wheel balance not the alaignment, get the 2 front wheels weighted and balanced, if they are wearing unevenly then it could be suspension bushes,track rod ends.

But most likely the wheels just need balancing only cost about $20 to 30 max

Hope this helps

I have a 2008 avalanche and my problem is the stabilt track and traction controls keeps coming on and causes the engine reduce speed sensor to stop truck from moving . Had throttle body replaced and still doing it , why is that?

check your wheel speed sensor (s) could have a bad or broken wire causing these issues.
