Ok, new to the forum. I have a 05 yukon denali with air ride suspension and approximately 95k miles. I need some help to figure out what I need to fix. The steering wheel feels sloppy and seems to wander all over the place while driving. I haven't heard the compressor come on in months. Height of the vehicle looks normal, no sagging. I just had new tires put on and an alignment done, thought it might help but still rides the same. Any help would be appreciated, thanks.
