hello, i have a 98 XJ 4.0. All i have done to it is a rough country 3 inch add-a-leaf lift kit and 32’s. As i accelerate, the faster i go, i hear what sounds like a high pitch squeak/ rattle. I may be wrong but it really sounds like it’s coming from the A/C vents. It only started doing it a few months ago and it’s getting very obnoxious. I couldn’t find a forum or any info about this. If anybody has any idea about what it could be please let me know!
