My wifes 2006 4.4 settles on the passenger front overnite "sometimes"
how do I recalibrate ride height settings?
Thanks

No, its called your air strut is leaking. There is no reset that I know of.

There's a ride height calibration that should be done. Through GT1 only.

Yes, but JT///MC is referring to socalkev's point about the car settling overnight- it should not do that. Recalibration will not fix it, there's a leak somewhere.

wow, what causes the air compressor to go out? Thats why at the first sign of the front shocks going out, I replaced them as soon as possible. I didn't want to tax the compressor and risk a failure.

Thanks guys, I'll look for leaks today.

Just got the latest update of my rear air suspension problem. Finally indy shop concluded I need to change only my left rear air shock since this the side that is sagging overnight. It will cost me about USD400.00 parts and labor.... I am just thinking if I should change both air shocks or just one. It might come out uneven heights if one is new and the other is old. Can I get some comments from our expert E53 gurus....

I'm no guru but just because you only change one shock does not necessarily mean it will be uneven. I would replace the bad one and verify that there is not a discrepancy in height. If they have access to a GT1, they can re-calibrate the ride height to compensate for any variations.

As to replacing the other shock, IMO, I would wait and save the $400. I'm under the assumption that they did not find any other suspension parts that need attention - because if they did, that's where I would put my money instead.

Good luck!

At your mileage, if one goes, one will most likely follow shortly. They're cheap enough, have both rear air springs changed.
