Thanks for the reply. I forgot to mention that the dealership’s foreman came out to tell me that he couldn’t find any TSBs on the issue and that these trucks don’t have a way to aim or level them. He said the way they are installed leaves the headlights fixed. He also, though, said there was no way to check them… Since it was light out.
As for the lifted rear end, that’s a good point about the suspension. I’d have to compare it to another Denali. But if it is higher, and the lights can’t be re-aimed or adjusted, then wouldn’t that mean they wouldn’t shoot as far out as they would in another trim level? Sounds like an oversight.
