I have 2007 LS 460L and have not had any issues since I bought the car back in April '19. Yesterday when I was driving down the highway I noticed something felt little off and I could feel like every bump in the road. Even the littlest bump felt like foot deep pothole. I then was getting out of the car and noticed the whole drivers side is up 2+ inches than the passenger side. You can even see from looking at the front the car is completely lopsided. I would like to dig into the problem this weekend but don't know where to start. I plan on buying the Techstream next week as this seems to be something you need if you are a Lexus owner. I would love to bring it into a dealer but I don't have couple thousand dollars laying around to have it diagnosed.

 

You have air suspension right?

Try parking the car on level flat ground, put it in HEIGHT HIGH mode and let it lift all the way up, then turn that off and let it lower all the way down. That should fix the issue. For some reason sometimes that happens.

If that doesn't fix it, you've got an air suspension issue. So hopefully it fixes the issue.

 

yes I do have air suspension system. Earlier when I was leaving work I press the height high button and I heard the pump kick in and then blow off when I got too high.

 

You can hear the pump? That in and of itself isnt normal...

 

I have to go to the very front of the car on the passenger side right by the front bumper to hear it though as it is very quiet.

 

Then that’s fine, did cycling the height help?

 

I will have to play with it in the morning. Did not get home till later this evening. I am going to take pics and measure heigths.

 

Ok took some measurements RF 29" RR 30 1/2" LF 31 3/4" and LR 30 3/4"
I tried the height switch and nothing went up or down. Even though when leaving work I turned on the height and seen the passender side rise. I will say it is higher on the passenger side than what is was Friday buy nothing will go down. I pulled off driver front wheel just to see any issues and nothing noticeable.

 

So you saw no height change with the high button? Somethings wrong.

 

I went out and played with it some more. On front drivers side I removed the 10mm bold connects to the lower control arm which is the height sensor I believe. When I moved it up or down I could here the pump kick in and heard it blow off ever once while. I did see change on passenger side go down on front and back by 2" but no change on drivers side. I would like to just temporary get it leveled out till I can get in shop. I heard adjusting height sensors but since the front is nothing adjusting driver side I dont think anything can be done temporary. Rides like hell and I drive it 3x week 500 miles. Also techstream what do I all need. I know usb to ODBII plug and software. I seen software run $70 for two days of use?

 

Welcome to air suspension, please ready up to $3500 to reenable function for the next 5-8 years.

Jokes aside you need to scan it can figure out what the system thinks is wrong and if it can see the height sensors or not. From there you need to go and pressure/leak down test each shock and make sure the valves allow air to move in and out of each one. If you can isolate at least those items you have a better stance to figure the issue out from the remaining items. Pressure/cycle test the compressor(s) next to make sure they are not weak or unable to build up enough to pressurize both sides.

 

I wouldn’t automatically say it’s going to cost you $3,500.

 

That's why I said "up to" lol, it hopefully won't be bad at all and may be something as simple as taking a hight sensor off and cleaning the contact inside (if possible, I don't know for a 460) to as bad as needing shocks and a compressor. It's unknown how bad it can be

 

Oh great... This sounds like a freaking nightmare. Guess I should done more digging before buying the nightmare car.

 

Put the tire back on ans started the car. Nothing changed on drivera front. I bounce the front femdee up and down hard ans then the front lowered but soon after it lowered all the way down for say 20 seconds it raised right back up.
