I need to replace the passenger rear bearing hub assembly on my 2004 Lexus RX 330 AWD. The car makes a loud hum as you increase speed and continues at speed. There are several manufacturers of the replacement assembly. Some start at $30 and go all the way up to $150. In my research I found that NSK brand is OEM. But here is my question. NSK offers two assemblies. One is around $85. The other one is around $110 but comes with a built in sensor of some sort. Can anyone tell me which one I need? Any help will be much appreciated!!
Thank you in advance.
