Air duspension

[Backinblk]

First I apologize for asking a 4th gen question but my friends having suspension issues and this groups been helpful with my 5th gen. He has a 16 Laramie with air suspension. He works 1/4 mile from home so truck only has 34,000 miles on it. Lately when he goes on the highway and goes above 45 the suspension drops to an aerodynamic setting. As it lowers it will say service four wheel drive and then it lowers onto bump stops. Ya can hear compressor run trying to fill but it won’t till he slows down. Any suggestions? Dealer just wants to poke n hope and throw parts at it. Maybe this maybe that. Any help is greatly appreciated

If he wants to keep the air suspension, it will probably be an expensive repair. Or he can buy one of the air suspension delete kits and swap in standard springs and coils .

I don't know enough about the air, but maybe a bad sensor.
