Title: Helping a friend in the morning/rear drive shaft removal
Post by: Blue J on January 02, 2016, 10:59:01 PM
I have friend with a 12 jku.  That says his drive shaft is just spinning when he puts it in gear, thinks his teeth on the ring gear may be shot. Is there anything special to removing the rear drive shaft or can I just loosen the bolts and remove it? I have never done this before. What better way to learn than on some one else's jeep. Planning to remove the rear drive shaft so he can limp home in 4 high on the front. Thoughts?

Make sure the front doesn't have a locker, especially a lunchbox or auto locker.  It will be the most terrifying ride home ever...just call a tow truck.  Where is he located now and where does he need to go...lots of trucks and trailers in the club.

I would be really suprised if every tooth on the ring gear is sheared to allow the DS to free spin. 

Something else is up.

He's the guy that got me into GATR. Jeeps at Lee road and I 20 at the gas station north of I-20. I'm picking him up at 8 and heading to the jeep. He lives just south of there off Lee road. There was talk of trying to get it to a mechanic/friend just 10 min more down the road to do the surgery/repair. It's a bummer because he just got this jeep in October with 73k on it. He rode Tray today so you never know what might have occurred. I wasn't with him.

If anyone is going to know about blown out ring gears, it's tcdawg! 

Can the factory dc cv joint get blown out to the point it causes what was described about the problem?

He said he lost forward drive and had to put it in reverse and creep off of I 20 to the gas station.

I anyone is around In The mornin and wants to stop by round 8:30-9:00 I-20 and Lee Rd.  hit me up 404-819-3941. I need some shut eye. Rode Flat Lands today. Was kinda worried because they don't all look like FS roads/Legal. More on that later I guess.

transmission is what I would suspect.  Again, @tcdawg is the most experienced with this.

After thinking about it...no need to remove the rear drive shaft if the gears in the rear diff are effed..just put it in 4wd.

But, based on what you just posted, and Tony's experience, I think it is something else.

Yep. Sounds like a Trans issue unfortunately

He said he saw fluid leaking from the front of the rear pumpkin, is it possible he just damaged thread drive shaft?

Why does this forum always post pics like my wife thinks I drive?  Itgoes in gear but the rear punkin is crunchy. Tow truck called. ....the saga continues.
Title: Re: Helping a friend in the morning/rear drive shaft removal
Post by: clark123456 on January 03, 2016, 09:24:20 AM
Wow...that's interesting for sure.  Some effed up angles and fluid.  Doesn't look like transmission fluid blown backwards...good!

Are you towing it to a shop or his home?  I want to see pictures of the inside of the pumpkin.  Maybe a broken pinion shaft?

I don't know if it's an optical illusion in that second picture but something really looks screwed up. It looks like pumpkin is pointing down? Looks like dif fluid is leaking

Let us now what the outcome of this is, curious myself.

yep, pinion angle looks dorked...like he has no suspension lift at all.  Had to be an optical illusion.

They pulled it apart and the pinion  and gears are destroyed. They rattled around and destroyed the housing. He may need a new axle. I talked him into calling Danny tomorrow. Post office delivered his CB this morning to add insult to injury  I am trying to get a photo.

Post by: SemperFiArms on January 03, 2016, 02:22:38 PM
Just saw the pics and it looks like the pinion bearing/s came apart and might have initiated the rest of the failure in the diff. Too bad to hear about the housing, ring and pinion are costly enough without having to add the complete assembly.
Title: Re: Helping a friend in the morning/rear drive shaft removal
Post by: Scott F. on January 03, 2016, 03:06:03 PM
I am curious to know if they were factory R&P or if it had been regeared.

Inside parts shown, or just driveshaft spinning?

Sounds and looks like the angle killed the factory driveshaft joint to me, and they will grab one way, like reverse if rounded off in forward position.

Video I saw was the driveshaft turning and a lot of wobble at the pinion side

Gotcha, if you can see the pinion flopping, its the gears.

Yea it the gears and pinion and.... I finally got Seth (Sasquatch) on the forum to call Allsouth tomorrow. The saga continues. He thinks the axle is shot as well...

Didn't he used to have an LJ with
white wheels on it 4 or 5 years ago?
Title: Re: Helping a friend in the morning/rear drive shaft removal
Post by: Blue J on January 04, 2016, 06:05:14 AM
Yep that's him. When is daughter was born he sold it for a family car and has regretted it every day.  He has been looking for a Rubi LJ but the jku really does make more sense as a grocery getter slash forest service road trail runner. He traded in his 07 jku for this 12 jku.  What causes this kind of damages? Is it too much speed in tight twisty spots or is it due to just being worn and possibly not enough regular msintence?
Title: Re: Helping a friend in the morning/rear drive shaft removal
Post by: cru9 on January 04, 2016, 06:18:13 AM
Has it been regeared?
Is it lifted with bigger tire or stock?
Title: Re: Helping a friend in the morning/rear drive shaft removal
Post by: Blue J on January 04, 2016, 08:41:07 AM
its stock....not sure on the re-gear.

Hey guys.

Jeep is completely stock with 4.10 gears. (Towing package). It had a vibration between 60 and 70 that was very minor. I figured it was just some mud.  It detonated the gears inside the pumpkin when I tried to leave the line at a stoplight. Apparently the guy looking at it says he's seen this before and there's a %90 likelihood I'll need a whole new axle as the inside of the pumpkin is trashed. I'll be trying to Allsouth shortly.

That sucks man, sorry for the bad luck.

Hope you get it squared away soon and possibly upgrade if you can.

They got everything apart this weekend. Looks like the pinion sheared.

Looks like maybe he broke some teeth first and it sheared when it bound up

I don't know enough about the interworkings and prefer to think that its magic instead. Whatever happened the magic went poof.
I have asked for more pictures but this is what they sent me.

I will probably be by at some point to document the carnage. I still want to know what causes this? Could it have been too much flex on a stock rig at Tray Mtn. I rolled Tray several times stock and never had an issue. My motives are selfish and I want to know if I need to beef up the rear driveshaft etc.
