Air Suspension Problems or Questions

FYI...I had problems with the air suspension on my 2004 GX470. At first I thought it was the ECU that controls the air suspension (Part #89293-60031) especially since both the right & left side were causing problems but it wasn't which would have been an easy fix.
The problem was the height control sensors for both the left & right rear. I had no choice but to get it fixed at the dealer. Part cost was about $450 each & labor/misc about $275 - total $1,175. I know it was crazy to pay that much but the guy who regularly fixes my car on the cheap couldn't figure the problem out.
If you have a good repair guy & have a similar problem, the part numbers are 89407-60022 (right rear sensor) & 89408-60011 (left rear sensor). I think different online part sites for Lexus shows the parts listed for about $290 each.
I didn't save any money but I hope this information will be helpful to someone & save him or her a lot of $$$$.

What were the symptoms of the problems you were experiencing?

Yes...replacing sensors fixed the problem. You will know when the sensors go bad because the height of the rear will go either really high or low & stay fixed at that height intermitently. The rear is suppose to adjust to normal when you reach a certain speed but it will not go to normal. The car will be really bumpy when the suspension stays fixed at high. I even tried removing the fuse for this feature after the height of the rear was at normal but the ride was too bumpy.
When the sensors go bad, you will know as the rear of the car will have a mind of its own.

I could be wrong, but I seem to remember when researching the GX last year the air suspension had a few components that were relatively common for failure, these sensors being among them.

yeah, suspension work isn't easy especially on this truck with so many extra parts, and the fact that it is a full size heavy as heck truck makes it even more intimidating to work on so i see lots of expenses i am gonna have to accept as i don't like to do electrical and suspension myself... oh well

I wonder if it affects the 05 too. I seem to have the same symptoms as dkong. My ride seems really rough. Like he said, a mind of its own. But I chalked it up to be worn out shocks since I don't see any codes popping up. Does a code pop up if the sensors are bad? The truck lifts when I start it up and lowers when I shut it off. And lowers and raises when I use the height control. The ride quality really sucks when I think of it. If the sensors are bad I gonna take it in to get it fixed. Extended warranty covers it. Dkong, does this sound like your symptoms too?
