So a few weeks ago I'm driving for about 10-15 mins and started to get a knocking/thump coming from the rear end. Sounded like rear passenger. It seemed rotational, and had a "one and two and..." rhythm to it. I pulled over and checked out, nothing seemed wrong. Less than a mile down the road the noise stopped and hadn't recurred since, until today. My wife was driving home and about 10 minutes in she calls me saying she had to pull over because the jeep is making a weird noise. So I came and got her and drove it home, which was about another 10 mins. After about 5 minutes it started making a thumping noise, but less of a knock and more of a rubbing/squeaking from the rear passenger side. Lasted maybe 1/4 to 1/2 mile and stopped completely. Tires were just rotated, pressure is good, rear diff oil was changed less than 5,000 miles ago. Rear u-joint was done 25,000 miles ago. Rear lower control arms were changed out from the last recall a couple years ago. Thinking maybe wheel bearings, worn bushings or something with the tri-link. Any thoughts or ideas to help me come up with a solid diagnosis?
