Hi all. New member. I created my account just to add my two cents here, as this issue is not really being discussed on my main forum. I have a 2020 Lone Star. I owned it for about 2 weeks before observing the passenger side of the bumper was lower than the driver side. Hood/grille gaps were even. It was definitely the bumper. I took it to the dealership and they refused to fix it, citing no adjustment on the mounts, and told me to take it to a body shop.
Body shop saw my truck today. Their explanation was that the passenger side bumper bracket was "twisted" in appearance, resulting in a .5" droop on passenger side. As opposed to wallowing out the mounting holes, they shackled my truck to the floor, then winched on the bracket from an upward angle, essentially performing a mild "frame straightening" job just to bend the mounting bracket. Having bent the bracket back to a level position through brute force, they corrected the bumper sag and leveled the bumper. They showed me measurements before and after showing the .5" in adjustment.
In the end it was a quick fix but required no shims, modification of the mount holes, and theoretically no structural compromise of the frame.
I paid $200 for my "bumper realignment". I understand this may not be the right solution for everyone in the this thread, but it's worth adding my experience in hopes it helps someone else in the same boat.
