Even though I didnt think it was the problem, I yanked the front driveshaft off and drove the truck around. No changes, it still comes to a complete stop as if im tapping the brakes just before it stops. As far as I can tlel though the torque converter is working as it should otherwise. Any other tips would be greatly appreciated.
Well I'm kind of excited. After more research I found a term used on this forum that seems pretty common called "stop bump" and it seems to be the exact problem in having. They say the fix is to remove the rear driveshaft and grease the splines from the transfer case to the driveshaft with a silicone based grease. I don't want to jinx myself since I haven't done this fix yet, but I live these cheap and easy fixes :-)
If anyone else has experience with "stop bump" I would appreciate any additional info.
My aunt had that problem in her '01 after the trans was rebuilt. I guess the shop didn't know about lubing the output on the transfer case. She described it as coming to a stop then the jeep jerking like someone bumped her vehicle. Worth a try to see if that's your issue though.
I lubed the splines the other day and to my surprise the jeep still seems to give a little nudge just before stopping. I was really surprised as I thought the "stop bump" was my exact problem. I don't know, maybe it's something with the torque converter, but it seems to work perfectly otherwise. Oh well, I guess it's not a huge deal, but I just wish the jeep rolled to a stop as smoothly as it does in neutral while in drive.
Its brake related IMHO. When in drive the engine is still trying to move the car forwards when the brake is applied but in neutral it is not. If you slowly lift your foot off the brake without touching the throttle does your car start to move forward? Is there much travel in the peddle before the brake becomes engaged/firms up?
You could let your brakes bed in. Or maybe change the fluid for new. First bleed the fluid from each caliper to ensure no air is trapped.
Ps brake pistons sticking on can also cause this check each wheel for excessive heat after a run out. If one wheel is hotter than the others then you have a problem.

I have the same issue as well. I can hear brake noises, chattering when stopping and chattering when releasing the brakes slowly. If I barely release the brakes the noise continues on until I fully brake or until I fully release the brakes. I have 2004 4.7 with Stillen one piece cast, cross drilled rotors paired with Stillen Metal Matrix pads and Akebonos calipers all around. Obviously I bled the brakes as well. I had the same issue before the brake gear swap and I still have it today even after the swap. I also bedded my brakes according to Stillens instructions.
When driving, if I put the WJ in neutral and brake to a stop I don't get the chattering which, to me, would indicate the issue is not the brakes. However, if I keep the WJ in gear and come to a stop with the chatter, shift into neutral and release the brakes slowly, I can hear the chattering a little as the brakes release. I almost think the issue is the transfer case wanting to keep moving the Jeep and the brakes are just chattering away when barely applied. I have no clue. I think the issue may still be related to the brakes but I have no idea. I do know that this is NOT stop bump.
Adding info... This also happens no mater if the brakes are hot or cold.
I'll take out my front driveline this weekend to test the hypothesis above that it may be causing the chattering sound. Still seems like the torque (TC, Driveline / Diff) is causing the brakes to grab on the roters and they're just grabbing... Deep thoughts I know. I just can't explain why even after a brake overhaul the issue still occurs.
