OK,
98 Expy with rear air susp. Seems I have a leak after I drove home from picking up a trailer. Parked it over nite and the next morning the rear dropped.
Checked for the obvious and jumped in and started up the engine, closed the door and voila! the compressor comes on, rear lifts up and stayed all day. Now I did check all the connectors etc. nothing seems to be leaking (soapy water test). #1 level sensor you think? #2 your opinion on LLS vs. a shock/coil conversion kit.
Thanks for any and all input.....
