OK to remove rear drive shaft???

heres my problem...I have this weird pop noise whenever I start from a stop or real slow crawl..It sounds like a little monster underneath my truck takes a wooden stick and knocks on my floor when I give it that first itty bitty bit of throttle..

Ive come to think it is either the tc skid plate popping when I give it gas or the rear end is torquing back and causing something to pop real quick?it doesn't sound that loud but I want it to be right!

so my solution for counting out the rear end rolling back and pinging a bolt or something would be to remove the rear drive shaft and test to see if the ping persists..

I wont even need to leave my parking space..just let the brake off and it will roll back slowly then I will put it in first and let the clutch out to give tension and pull it back into its parking space.

when I start the jeep without a rear DS in will the fluid be pumping and flow out the tail shaft?how much will I lose?if any?

I have no sye!!
any help would be appreiciated..I just want to start narrowing down this noise

It's probably your t-case linkage. Since you dropped your t-case, you misaligned the linkage because the linkage is bolted to a bracket on the body. Best bet is to buy a re-location bracket (I bought Advance Adapters) and that bolts to the tranny itself and the linkage is now independent from the body.

it does sound like it is coming from my side of jeep..also feels like its under my butt..so I thought that same thing so I adjusted my linkage and all that jaz..(I wasnt going to do it cause I plan on ditching the tc drop but thought this would help)anyway what would be binding on that??everything shifts fine in and out of 4wd hi and lo?the linkage and crap do look alittle twisted maybe Ill take a closer look at that stuff!

Same thing happened to me when I installed my 1" body lift. It shifts fine, just it is contorted so it'll rattle... even with the drop bracket. Of course it'll be fine once you get rid of the t-case drop. I recommend the re-location bracket though.

I'm not getting a rattle just a one time pop every time I go from stop or let off gas and relieve any torque and then give it gas again...still sound like my prob is this linkage??It sounds as if a shock is loose or something and every time I apply pressure to it it buckles...already checked those though..everything seems to be tight?maybe I should just live with it for another week till the sye is done?Ill just hope its just this linkage crap?

TJ transfer cases don't leak when the rear driveshaft is removed like the YJ transfer cases did.

How's your rear axle's pinion angle? You sure it's not the u-joints on the driveshaft going berserk from a bad pinion angle?

It's hard to tell even with those good photos but since your driveshaft is a conventional (non-CV) driveshaft, just insure the rear pinion shaft angle is exactly the same as (parallel to) the transfer case output shaft. The pinion shaft angle kind of looks a little too low to be perfectly parallel to the t-case output shaft but it's really hard to tell for sure.

you dont think that would be enough off to make a popping sound do you?I did notice the linkage for the 4wd does look a little contorted?if it is the linkage do you think I will ruin anything by driving like this for another week?

popping noise

I had a problem with similar symptoms a while back.

Found out that my lower control arm bolts had worked loose and when ever I would take off they would slide just a little bit.

If you look at the mounts at the frame you may see where mud/grease/dirt has been rubbed off from the arm moving back and forth.

That was my experience anyways, may not help you but definitely worth checking out.
