Hi there, Well the three amigoes turned up after along holiday so on sunday went looking for the cause the RH rear sensor was not picking up a reading when moving (used my rova com lite).

The ohms were o.k. and voltage from the ECU checked out so off came the wheel, caliper and rotor to pull out the sensor the end was stuffed heaps of gouge marks and pushed in plus a bit of metal stuck on the end.

Can only guess that something is falling apart in the bearing assembly so now have a new hub and sensor to change out this weekend $580 dollars out of slush fund will post pic's and let you know what i found if anything!!
