Ten days after 4.56 regear on front axle (did rear last month), I got on Interstate..... first time over 50 mph since doing the work.
At 70 mph, heard rumble from front end and felt a light buffeting in the steering wheel.
Got where I was going and looked front end over.....nothing apparent.
When I got home I crawled all around the front half on the TJ and found nothing, including no excessive heat from frt differential??
Was formulating how to word this post as I stood up on passenger side.
Discovered the door was not closed all the way!
Having just reinstalled full top, I was not use to driving sounds. Noise was from higher speed on M/T tires, made more evident by door not being sealed ...... and the buffeting was from disrupted air flow due to door not being fully closed.
Closed it and went back out on Hwy to test..... problem gone!
I'm still learning about Jeeps, obviously! ANYONE ELSE had an experience this stupid??
