Hello everyone, I have a 1992 Lexus LS400 with air suspension and I need to replace the left rear ride height sensor. The part I need is discontinued by Lexus. Part #89408-50020. Does anyone know what the best aftermarket part would be to use? Also..is this part easy to install? And if so can anyone send me a link to install it? I couldn't find anything on YouTube. A response would be greatly appreciated. Thank you!
