Bought a used Navigator a few months back and honestly it's been a fantastic highway cruiser for the family, rides like a dream when everything's working. But last week I noticed the rear end seemed a bit lower than usual when I came out to the car in the morning, and after driving around it leveled itself back up but now I'm paranoid every time I park. I know these air suspension systems can get expensive really fast if you take them to the dealer, and honestly I'd rather not go that route because I've heard they just want to replace the whole compressor and bags instead of actually figuring out what's failing. I've been trying to track down a decent lincoln garage abu dhabi that has experience with these American SUVs and actually understands how to diagnose air suspension properly instead of guessing. I'm hoping it's just a small leak in one of the lines or maybe a sensor acting up rather than a full compressor failure. Anyone with a Navigator or Expedition dealt with this before and found a shop that knows these trucks inside out? Really don't want to get ripped off because the car's been great otherwise and I'd like to keep it for a few more years.
