I did not watch the video. But this is a very confusing story. Are we saying that the Tone Ring was missing? When you replace the rear rotor, that part must be transferred. But you would know right away as you'd be getting codes. Or was it just that the speed sensor needed to be replaced? As mentioned before. If the sensor was impacted by something during the tire service, that would be enough to damage it.
It's not the Vredestein tire (which several have pointed out). It just isn't. We've put a few hundred of them on, not to mention other aftermarket tires, with just 1 issue, which is unrelated to this problem.
I can't imagine that it's the aftermarket rotor, though I'm not there so I can't be sure. I do not know of an aftermarket rotor that is as poor quality as the OEM product fitted from the factory. To be fair, most are fine with the OEM rotors. But they are just above the bare minimum on the quality scale, (my opinion).
I hope they aren't just throwing parts at the problem, hoping to get lucky. Admittedly, we all do it. But the items sighted here just don't fit the bill.
