I have a 2006 Jeep Wrangler 2.4L 4 Cylinder 6 speed manual. It has very low mileage; 44,260. I got it new and have owned it since 9 miles on the odometer.
I got it when I was younger, and I put a 1" spacer body lift, and 2" suspension lift in it. I ran 30" and then 32" tires in it for less than a year total. It spent some time off road, but less than two years and probably 20 trips. I then garaged it for about 3 years.
After garaging it I drove it as my primary vehicle in Boston without the 2" suspension lift, and back to stock tires. It still has the 1" spacer body lift in it.
My jeep started making a strange noise in 2012. It was sporadic and I took it to a few different places and they didn't seem to concerned about it.
I have since been using a VW Jetta as my daily driver, and my Jeep has been sitting outside. Until recently it was unregistered/uninspected. It just got back from inspection and I am noticing what seems like a crazy loud noise coming from underneath the passenger seat when attempting to accelerate. It does not happen when the vehicle is coasting or when the engine is revved with the clutch disengaged.
It's almost like a groaning/grinding couples with what almost sounds like a fan?

I live in a city and don't have access to putting it up on a lift on my own right now. Any suggestions or should I just take it to a mechanic and tell them to drive it around? I'm thinking it may be Transfer Case/Transmission- I know I have not put in new fluids/checked the fluids myself since owning the Jeep. Since it seems to be getting worse I am wondering if it could possibly be something fluid related.
