I’ve jacked up 2 days ago and taken all brake hardware off, this is the sound I got which made me think wheel bearing chasing my noise.
Link Here I was simply doing fluid fill as a preventative item because other people have checked 1/2 times per year and I figured it’s time. Turned out to be more. I understand what you’re saying completely. I may try your prop shaft method backwards, spray with brake clear and silicone lube and see if it goes away, if not remove and see if it goes away. If propshaft is also bad that may motivate me more to the trade option. There are 2 bearings that I should try spraying, If I remember correctly it’s a sort of 3 section part? I also just spent 5-6k on whole new top end and oil cooler job so I’m at a loss here not sure which way to go. This is my second cherokee and both have left me high and dry all while doing lots of preventative maintenance (the stuff everyone says should prevent these problems like synthetic oil every 4k and checking fluids often, that’s just my luck I guess

)
