If the back end is VERY noisy like mega-road noise roaring its likely the axle bearings. I would inspect it all as mentioned and replace the axle bearings while your at it.

I do hear a wheel bearing, but the very LOUD noise from the back end is different. If I'm coasting. . there is NO noise. If I'm driving, or accelerating, then it is VERY loud. Seems like this might more indicate a bearing other than in the axle or wheel. I'll fix the wheel bearing(s) first, then see what's next. Thanks for all the help!

Oh. . and "QD" . . is that QuadraDrive ? I think I just have "Select-Trac" . . . not QuadraDrive. Sorry, I haven't had time to do any research here yet. Do I still need the limited slip differential fluid?

Seems like if I'm going to take apart the rear, then I should just replace all the bearings. How many are there? Is there a rear-bearing kit someone would recommend?

I had the same issue of the worn lock cylinder and ended up replacing the lock cylinder with a junkyard one. There were a few times were I started it with my Acura Integra key and didn't notice it until I pulled it out

I'm pulling off both rear axles today, and will press on new bearings this weekend. Wish me luck. . never done something this big before.

Wow. Taking the rear axles out was super easy. Actually, it was easier than doing brakes. Wheels off, two bolts for caliper removal, 4 bolts for bracket removal, slide hammer pulled out the axle in 3 whacks. Had both axles out in 20 minutes. I can't believe I almost paid someone $400 to do this. Will press on new bearings on Monday.

Came out this morning, and the interior lights were on. . . strange. No one has touched the jeep all night. I opened and closed a the rear driver side door, and they turned off. Dang. . either means another wire short, or a bad door switch. I'll probably just start disconnecting switches until this behavior stops. Any other reason why the interior lights would just come on randomly while the jeep is just sitting there?

One thing I love about The WJ. Fairly simple to work on. My aunt has a Nissan Pathfinder and I will not touch that thing. Talk about cluster ****. God bless American engineering!

The wiring you removed was for a key bypass for a remote starter. The connector would've plugged into a "coffin box" that would hold a key. And like you said the ring went up to the key cylinder to transmit the transponder code in the key to the cylinder.

Check the boots in the door as mentioned earlier. I have an 04, rear speakers didn't work. Had a complete stereo setup and while my guy was doing it, he found 8 broken wires between the two back doors. He fixed them for me. This Saturday, windows stopped working. Sunday I took apart the boot, two broken wires. I fixed them and all is well...Until the next wire snaps. If it's not that, check the switch at the door (dont know technical name) that opens and closes the circuit when the door is closed and opened.

Well . . I got the axles back in today. It was pretty easy. However, the noise is still there. I checked transmission fluid, and rear differential fluid. Is there a separate reservoir for the transfer case? Perhaps that is low on fluid.
