Ok. So I have the same issues with my Titan Le. Leaning. I thot the suspension was a great place to start. Cause the Frames not bend nor damaged. After replacing the suspension the problem with the leaning truck was still their. After Months of looking for the right answers online. I couldn't find anything. However... I found out the SRS seat belts could be the reason for my problem. Maybe also ur problem. Let me know.
