While I agree the prices are much higher now you can surely get a better lease deal than what they quoted you. I would look around at other dealerships for quotes or go over to the leasehackr site. I've seen deals in the $500 to $600 dollar range being posted over there.
I also have the rattle in that area and now a new place that seems to be around the steering wheel area. I have tried changing the steering wheel positions to see if it will stop but it doesn't seem to help. IMO, this 2023 truck has been a rattle can from since I got it so disappointing. My 22 limited didn't have any of these issues.
Haha, I still have to do three point turns on most of my u-turns and have some slight rubbing at full lock sometimes. I'm on the stock 20's. Other than that no complaints and knew I would lose some turn radius before hand do to the lowering kit.
