Gx 470 / Air Ride Problems

[sledder]

I finally had a new ride height sensor instlled on our 470 and now the suspension sometimes leaks air to the point the axle housing is against the bumpstops. It doesn't happen over night, but over time it does go down.

Could I have a leaky airline somewhere?

Why wouldn't the system automatically correct this low ride problem everytime the vehicle is started?

Thanks
