Hi Guys, hope you can help, car failed Mot on front ball joints and ABS fault, car is `09` 407sw, changed front joints myself, relatively straight forward job:thumb: ABS fault had already been pinpointed as O/S/R sensor fault, checked sensor, sure enough broken wire, tried to repair, did not work. purchased new sensor and fitted, remembering to drop the fuel tank. whilst fitting sensor, noted cracks in ABS exciter ring, used a suede brush to clean off dirt to check more closely, ABS ring fell to pieces and parts dropped off refitted wheel etc, knowing it should fault again, sure enough 20mph+ abs light back on. My question is, is it possible to buy the ring as a spare part, and is it an easy job to remove the rear hub to fit it?. all help gratefully received, Regards, Hornet1068.
