First time posting with a question. I've searched and cant find the answer.
I bought a 2003 celsior from Japan.
I purchased rims for the car.

The location for changing the rims over wasn't very level and because of this I had to change one side at a time.
Starting the car, backing it out and driving in with 20s on one side and stock wheels on the other.

I noticed right away after I put the 2nd side of wheels on the car didnt sit level.
Seems like one rear side for sure sits lower than the other.

Is there something I should have done prior to jacking the car up to keep the car level?
I haven't tried jacking the front and rear of the car separately to see if it levels out after fully extending the shocks.. any thoughts?

 

Drive it for a couple of minutes and then park on totally flat ground.
Leave the motor running for at least 30 secs, then measure from the ground to the same spot for left and right.
The air-ride has level sensors so it can look skewed if the ground is not TOTALLY level when ya shut the motor off.

Having 20s on one side and stock wheels will probably have thrown it off as I doubt that they are exactly the same rolling radius.
Running with all the same sized wheels should set it back to level.

 

I have put about 600 miles on the car since I changed the wheels. It still sits the same. It's like it leveled itself when I had the 2 types of wheels on but now it wont level with the 20s. My garage is very level. Its parked for the winter but I start it regularly..
it runs for 10 mins or so each time I head out.
I've measured and still no change. It was perfect prior to changing the wheels.
driving me nuts lol

 

Have you "rebooted" your car? I would park it on very level ground and disconnect the battery. Give it a minute or two and reconnect. Easy to just disconnect the ground cable. Worth a try.

 

Also may be worth setting the suspension to high, and then back to normal with the engine running.

 

I'm thinking of jacking up the back of the car then the front, fully extending the shocks.

Maybe that will make it level itself again.

I dont have the manual. Is there anything about jacking these ones up with OEM air ride I should know?

 

I was thinking the exact same thing. Tried it. No go.

 

I would be plugging in to Techstream next I think. A quick google search will hook you up. Easy for me to say, I have to get mine set up, but have not had a compelling reason to do so yet, too many other priorities.
