    Default Vibration and intermittent ABS Fault?

    Well, following on from this thread....

    http://www.vectra-c.com/forum/showth...ng-in-the-rain

    The car has developed a harsh vibration through the steering wheel when moving. I think its the front drivers side, as I can feel the vibration through the floor.

    So I'm guessing that its probably a wheel hub bearing?

    Now, someone has also mentioned that my intermittent ABS fault could also be related to this "wobbling" hub...?

    Does anyone have any advice on how to check wheel hubs?

    I've looked at the How2, but the pictures are all over the place despite being a good write up, I just cant seem to make sense of it with them all over the place! LOL

    Jack up and spin wheel listen out for any noise should be quiet and feel smooth.
    And yes could also be causing ABS light to come on

    Well, gave the car a wash, ABS warning came on...

    So had the car up, wheels on... gave them a good spin, pull, etc... nothing....

    Car up, wheels off, gave them a good spin, pull, etc... nothing...

    I've pored a full watering can over all over the sensors and loom, a wheel at a time... again... NOTHING!

    I can never seem to replicate the fault when I want to!

    Anyone know if faults like this are stored in the ECU and can be read with dealer software? Or are they only readable when the warning light is on? I know its a Saab, but its still a vectra-c underneath... lol

    Aslong as they are stored they can be seen yes.

    The problem is that after so "x" amount of clean drive cycles the ecu will no longer store it

    Try putting some contact cleaner/ wd40 on the abs module plug
