jeeperman Depending on your limited slip that you had installed, as little as 1/2 pound of pressure difference in the rear tires could cause a lot of heat to build up at speed... Check to see if the pumpkin is getting hot, and see if the belt is unusually warm, other than that, it might just be oil that dripped on something, and gets hot when you run the engine hard...

Weird smell at 45MPH+

I have a 97 Jeep Wrangler, 4banger. Recently I got a rear differential changed. Went from an open diff to limited slip (posi) differential.
After I got it done, there has been this weird smell coming when i hit around 45 MPH. when my window is open, it is strong and when its closed it is not at all.
The closest i can relate to that smell is like smell near lot of factories. It is definitely not coolant and most likely not oil.
I got it checked and when hoisted the jeep, there was no oil or any thing falling on the exhaust system. It does not smell when I stop. Tried to smell to the source of the smell but failed.

Also i recently got the idle pulleys (on serpentine belt)changed.

i have no idea where the smell is coming from or what it is..

It is kinda hard to explain what it smells like but i gave the best description i could..

Any help suggestions would be greatly appreciated.
