A while ago, i needed to replace mine as well, due to noise, which means that the sensor worked. I tried a used one, but i had the opposite effect: no noise, but also no signal, and i had a fault on the dash. I searched everywhere and on some Toyota forums i found that some people suggested cleaning the rubber part and the signal would get back to normal, which in my case did not work. I believe that it never works, as it's not only a matter of dirt.
I have also searched for alternatives on aftermarket brands and the result was zero. Only on company told me that they were in the process of building an aftermarket bearing, but it needed more time to complete.
Luckily enough, just at the time when i was mentally ready (
) to pay 800 pounds for a new one, i came across an offer from a UK dealer, who offered it for 300. Paid, installed and went to the mountains to drive my car. Some months later i spoke to another UK dealer (the best known here on the forum) who also offered the bearing for 300. I asked him why he didn't tell me this earlier, and he replied that the discount came from the factory.
So, i believe it's a matter of patience to find the correct price. We all know that Maserati does not help their customers with aftermarket parts, this is a scenario we have to live with.
And, to conclude, even if cleaning the rubber would be succesfull, which i doubt, with a new bearing now, i feel more secure while cornering. As for aliexpress i do have some positive and some negative experiences, as others mentioned. Not all Chinese products are ****, but there are a lot for sure.
