I'm assuming it is under factory bumper to bumper. If so I'd start with the dealer.
Other option is to get it inspected; start with a suspension place. When suspension wears it gets loose; lift the truck up and start wiggling stuff.
If the air suspension is bad it'll leak and the compressor will run a lot.
We had some magride shocks go bad, they leaked, it was visible on the shocks themselves.
Yes, ride quality would be different, effectively you wouldn't have any damper.
Update for all who have chimed in:
Brought Yukon to the dealer. They balanced all 4 wheels, added new Michelin tires, did 3 alignments. Yes 3. It was so bad, they asked if there was any suspension work done before I brought it in. I am the second owner so I had no idea. The Chevrolet dealership I bought it from had not done any.
After all that, the truck still rides like absolute garbage albeit straight and without wheel vibration. It feels like there is no suspension at all. Bouncy and extremely harsh over any road imperfections. The entire truck slams everything. The dealer test drove it when I brought it in and didn’t mention anything about the ride being “bad”.
I honestly don’t know what to do at this point. I’ve already dumped $2,500 into this thing in the first 2 weeks I’ve owned it and I don’t want to continue down the rabbit hole even if it’s under warranty. Dealerships don’t care to help.
Do I cut my losses and take the $7k hit if I trade this thing in? Do I continue to try with any dealership to help fix it? Someone talk me off the ledge haha
