I too drive around 2000 rpm regularly and that's where it seems to make the noise the most. I also tried driving at higher rpm, but around 3k rpm the engine makes quite a bit of racket like you mentioned.I agree the tire/gearing explanation unlikely but it was worth mentioning for redundancies sake. And yeah we need more data, we need to find what we all have in common and what we don't have in common with Jeeps that don't make the sound. That should point us in the right direction.
Every time I drive it's all I can hear and it's driving me crazy.
What RPM's do you guys typically cruise around at? For me around town I'm usually around 2000, sometimes lower than that in residentials at 30mph I'll be in 3rd and the RPMs are at like 1200. Highway when I can even use 5th at 70mph is like 1600 RPMs, 4th at 70mph that usually sits at like 1900.
I know people are going to tell me that I need to drive at higher RPM's than that and I'm lugging the engine and I've been adjusting that, the only reason I've normally driven like that is because the engine is so damn loud at 2000+ I figured it was too high, I've done my research and have adjusted accordingly though. I wonder if all that time driving in low RPM's has something to do with it.
