I had this problem before with a customer truck it was a bad wheel speed sensor. If you take a volt meter and plug the leads in to the wheel speed sensor wires turn the meter to A/C volts low scale. Turn the wheel one revolution per minute you should get a lease 350 to 500 A/C volts on each front wheel. If you don't replace the sensor. If you do then the sensor is ok keep looking GM had a service bulletin on this problem caused by rust. Good Luck
it needs the hydrostatic fluid replace are it may be low on fluid best to replace the fluid do it right now if you wait the hdro pump will burn out then wont move at all and you will have to pay 300 hundred dollars or if you can find used one 150 dollors
this problem is evident in vehicles that have a strut suspension
at the top of the strut there is a plate that is the top plate for the suspension coil spring
above that plate in the rubber bush is a bearing
if that bearing has failed then the plate will not turn and when you turn the steering wheel the power steering is in effect winding up that coil spring
that makes low speed turning very heavy on the power steering system especially at low rpms
have the front suspension checked for that bearing failure ( both sides ) by an accredited suspension specialist shop
standing stationary and turning the wheel you may even hear a creaking or groaning noise as the spring is flexing on the strut
if you do not have a strut suspension , take it to a power steering specialist shop for a proper diagnosis
most likely the problem is you have a wheel sensor that is not working properly, the traction control system is constantly monitoring the wheel speed to make sure all wheels are spinning at the same speed if it sees one wheel speed up then it thinks it is slipping on the pavement like ice or snow then the system will apply a little brake or power witch ever is needed to stop that wheel from spinning. if the system constantly sees one wheel that is turning faster or slower then all the other wheels it will turn on the light and shut down the traction control system, by the way a low tire can set the system off.
If the low traction light and the ABS light are on, chances are the system is reading at least one wheel turning faster than the others, and is interpreting this as a slipping tire. I'm not sure how much the measured speed difference needs to be to turn the system on - maybe even an undersized spare tire could do it.
If you know it isn't the tires, you may have a problem with one of the wheel speed sensors. These detect the slots in the edges of the brake rotors. Check the wiring harness to the speed sensors - it gets a lot of abuse on the bottom of the car. A replacement rotor with different slot spacing could also cause the problem.
If the sensors and wiring are good and not sending false signals, then the ABS controller is at fault.
Normally this problem is caused by a wheel speed sensor.Every wheel has a sensor to detect the mph of each wheel. the vehicle notices any major difference in wheel speed and makes the tcs light flash at you or stay on all the time.This is how the vehicle knows if your spinning or losing control of your vehicle.Have your mechanic verify that all the wheel speed sensors are working properly and have him check for diagnostic trouble codes in the computer. Hope this helps,
Sounds like maybe just rust on outside edge of rotors is touching on spindle slightly. Try removing wheel, and check rotors for rusty outside edge. Take a hammer with safety glasses on, and tap corner of outside edges of both front & backside of rotors to remove that rusty edge. See if noise is gone after. Inspect your brakes while your at it for worn pads.
The speedo drive sender is very common failure on these bikes following any maintenance involving the front wheel removal (like tire replacement) The speed sensor is located on front axle on the right side of the wheel The magnetic rotor gets broken because the drive detent is not properly engaged duing re-assembly. Fortunately the replacement is relatively inexpensive and reasonably easy to replace if you are careful to engage the drive properly when re-installing wheel. Insert the drive into the wheel before bringing wheel up to forks and inserting axle.
