My turn: axle u-joint?

Oh shit lol well the rear driveshaft CV end goes in front. That's what I get for answering after two dinner cocktails.🤣

Snort! Now you have me more confused than ever. Driveshaft in question:

When this is completely disassembled, can the main part of it be swapped end for end? In other words, the arrow I drew on it pointing the other way?
 
Nevermind Jerry with his CV joint nonsense. You don't have a CV (actually DC) joint on your rear driveshaft.

As B1Toad showed, it only matters for balance. You should try to reassemble it the same way it came out, because part of that balancing process involved the front yoke. Usually, replacing U-joints won't mess up the balance, because they're fairly compact, uniform, and symmetrical.

That's also why you mark everything like you did, you want that yoke to go back exactly like it was. I even mark the differential although I doubt that matters. On the driveline and yoke I use a prick punch, the chaulk could get worn/washed off.

Bright pink fingernail polish works very well. Most of us have to borrow our wife's polish, but Zorba probably has more colors than she does.

It does - and I do have more colors, she seldom does her nails. But I just used a white paint pen. After I get it apart, I'm going to give it a coat of paint, so I need to keep track of what's where through the painting process. @B1Toad 's punch idea sounds workable.

Bright pink nail polish is my go to for when I need to highlight gun sights.

You can also use nail polish in lieu of LocTite in a pinch

I've done that a time or two on small stuff. Don't remember what color though...

EDIT: Actually, now I do. There was a makeup grab at a Belly Dance class I was in years back - and there was a bunch of nail polish - including an ugly brown shade (!!). I used that for loctite and even glyptol on calibration potentiometers a few times.

I wouldn't trust nail polish to dry in the threads, it's aerobic, not anaerobic. But it works great for locking small screwheads in place on electronic equipment.

Come to think of it, I have more colors than my wife too. Because she bought me a cheapo set of the brightest colors she could find.

I use bright orange on my gun sights to match the ones which came with the orange insert.

there's a kind of ratcheting motion on sharp on-pavement turns

Sharp turn + single U-joint = changing velocity . The " ratcheting motion " is totally normal . Remember when high end XJ s came with full time all wheel drive?
those Dana 30s came with CV type joints in the axle ends , ( like a front wheel drive car ).
Good luck with your repairs . and buy some damn tires .....:LOL:

driving the jeep in FWD, makes me believe the axle U-joints are bad as well, there's a kind of ratcheting motion on sharp on-pavement turns (read: Parking lots).

That’s no reason for concern. It’s the nature of u-joints, in that while operating at an angle, the output speed fluctuates. The sharper the turn, the more fluctuation, and high grip surfaces such as asphalt make it very noticeable, whereas offroad the tire would just slip against a loose surface.

New Spicer U-joints have made the scene. Goddess only knows when I'll get them put in though. The old one I examined is also a Spicer, but evidentially an older type as it has different markings.

@NWPA Jeepy T Nailed it - its the forward rear driveshaft u-joint. But not to leave @Jerry Bransford out, driving the jeep in FWD, makes me believe the axle U-joints are bad as well, there's a kind of ratcheting motion on sharp on-pavement turns (read: Parking lots). The driveshaft removal was as easy as everyone said it was - so easy even a Belly Dancer can do it!




for the ratcheting… didn’t you install a lunchbox in the front?
