I have an 03 rubicon with 108,000 miles. 4" procomp lift and goodyear mtr tires. Other than the lift, it's stock with an automatic. I picked up a strange noise about a week ago and I'm stumped as to where its coming from and am hoping the forum can help me out.
At first I thought it was the sepentine belt tensioner, which was worn, but after replacing it, the noise remained. A friend rode with me and we thought we traced to the rear end, driver side. I pulled the axle shaft and replaced the bearing, and the noise remains the same.
I have checked all four wheels for bad bearings, and they feel solid. Ujoints check out ok too. there is no vibration or shaking at any speed, just a noise.
The noise speeds up and slows down to match RPMs, and goes from a hiss to a low rumble as I slow down. I'll try to record it and post later. Any help is appreciated.
