2006 Jeep Grand Cherokee 5.7- ABS issue with left turn.
This car came with Abs issue. The car came with the wheel speed sensors damaged or not all were on the wheels.
We got new set of 4 and install it on the vehicle...
Now when you plugged in
Front left, front right, rear right and then you drive the car and make a left turn to driver side, car moves freely without none of the tyres or drum locking to brake or ceases.
But when you plugged in Rear Left sensor, and you turn car to the left side, the left rear tyre or disc or rotor locked or brake is apply automatically..
Being trying to figure this out but to no avail... any suggestion would be appreciated or who ever face a similar issue can help me with guideline
First thing I would try would be pull out ABS sensor zip tie it leaving it plugged in or use a soda can shim to keep it from pushing flush on reinstall test drive if still locking up probably a com error on the ABS lines or bad sensor. If it fixes the problem then most likely a bad wheel bearing and left turns move it just a hair causing the sensor to tell the ABS system its sliding.
But I still do most old school I am sure someone has the proper testing procedure.
Almost certainly a wheel bearing to sensor air gap issue. The clearance between the bearing and sensor is ultra critical .Normal way of testing is to use a scantool that will graph the speed output of each sensor and look for dropouts or glitches in the signal.
