Lowering Ls430 Air Suspension


Recommended Posts

Does anyone know how to lower a 2001 LS430 with air suspension??? I've had people do it for me 2 different ways before.

1. Manually releasing the air from the air suspension controller & lowering each corner one by one.

2. Tapping into the wires that control the air suspension & possibly reversing the power with a power probe.

The first way can take up to two hours if you don't get a grip on the hose & it slips out of your fingers (it's very small) & you release too much air. The second way can be as quick as 5 minutes. The problem is, the guy that knows how to do it the second way charges me to do it each time. The wires he tapped into are still there, but I have no idea how he gets it to go down. I know you need to remove the relay for the air suspension, but what do I do next? Does anybody out there know? I would keep it at just one height, but my air suspension somehow leaks air slowly & over time, usually a period of a month or so, & I will have to raise it again as it starts to rub.
