Alright guys, i did some adjustments to the front two collies ( took the helpers out ) for more lows ( Two days ago ), everything fitted perfectly no worries there, now i start my car, ABS light comes on, next time i drive, the ABS light is off, bit temperamental at times. But now ive been driving with the ABS light off and my speed meter will randomly go to like 80MPH to 100MPH back down to around 70MPH ( could be anything it flips in between, not only them figures ) and back to the speed im going at say for instance 30MPH, then the ABS light comes on, thats happened to me around 4-5 times now and not too sure what is wrong with it. first few times it happened i took the wheels off to see any loose connections but everything was fine so im really not too sure, would any of you guys know whats wrong? im pretty much convinced its to do with the collies and fitment ive just done but i dont know why because it was done fine and fitted back normally. thanks, Rory.

sounds like a problem with a speed sensor perhaps. that would explain the speedometer jumping around and the speed sensors determine how fast each wheel is turning so it can determine where to apply anti lock braking at your wheels. when you brake fairly hard are you noticing the brake pedal pulsing at all or any abnormal braking symptoms?

no that was thefirst thing i tried is braking hard, everything felt smooth and normal to tell you the truth, noticing driving today the ABS light is always off until i hit a pothole on the right wheel then it goes crazy then the ABS light comes on

take the bulb out
