Knocking type jingle from rear yoke

I finally got my new jeep and of course something needs fixing. As I drive I can here a clicking or light popping from rear end. It's not from bumps its there on flat road. I jacked it up and put it in gear. N seems it's coming from the rear driveshaft and the rear diff yoke. As I hit the gas a little bit it looks like it moves and start clicking. U joints are tight and don't see any play in it. It's more when I gas it and let off the gas but at normal speed it clinks as well but not as bad. Btw it's a 2006 unlimited 2 door with the 4.0. With 3.73 gears. Could it be pinion bearing? I don't ( hope ) want it to be something costly cause I might as well stick some better gears in it. Maybe 4:56 ? Gonna go 33s maybe 35s and do some wheeling mostly weekends trailing and hunting. Thank you guys

take the driveshaft off at the yoke and inspect the u-joint, it might look nice and tight visually, but looks can be deceiving ...
Cheap and easy check

Check the torque of the yoke nut also. You don't know if anyone has tampered with anything back there. remove the bearing caps from the U-Joints and see if they are dry. Now that you have removed the drive shaft, go ahead and install new front and rear U-Joints, and transmission and transfer case mounts.

Thanks for some input. Gonna try and check them out tomorrow. Guy I bought it from said his son went out and missed it out so who knows what couple happened. When I remove the drive shaft. The yoke should have no movement or play? The 44 is C clip right ?

No 35 is C-Clip, 44 axles are held in by outer bearings. Does it have a limited slip diff? That could make noise. My TJ had a TrakLoc and a piece of a clutch disc came out and wrecked the R&P so I ended up regearing it.

I haven't really had any time to get to it. New baby 4 days ago. So time is tight. I'm bringing it to my friends shop n he's gonna look at it. It kinda seems like it's the angry sparrows like said couple replies back. With the center ball. If it's something that gets deep into my pocket to fix it. Should I just spend the xtra and get it regeared ? Gonna run 33 maybeee 35s. Thanks

Congrats on the baby.

What gears do you have now? I regeared mine when the rear had to be fixed, also added TrueTracks front and rear. I went with 4.10 but I hear automatics like even lower for 33s. 4.88 would probably be good if you are thinking of 35s.

I have 3:73 gears now. I hope it's a cheap fix cause i didn't plan on regearing unlill I had the lockers to install at the same time maybe save me some money. If I did 4:88 would that be fine with 33s

I think 4.88 would be a bit low for 33s but let you run 35s later. I am pretty happy with 4.10s but I only have 32s.

I'll be happy with 33s.. But still need to get it fixed. I'm really thinking it's the angry sparrow noise I've been hearing? If so whats the main culprit ? Center ball?

Got the jeep figured out. Rear ujoints were toasted. Rusted/seized together that's why there was no play. Replaced em. No noise. Cheap fix. Idiot mistake not looking first
