Not ever hearing of this or knowing anything specific i can only guess and just trying to think/imagine what could cause this.

It seems as there's only areas that could even do this, t-case and brakes. Although since you have mentioned a nasty noise that came from the t-case i would think its safe to say that's your problem area. Now, what could cause that... again never been into a t-case personally i can only guess. Perhaps a worn or broken shift fork? chipped tooth getting wedged when the reverse motion is happening? accidental shifting due to damage or worn components?

Well, that's probably enough of me taking up space. Just pondering. Interesting dilemma, i'll be watching.

[XJ Wheeler]

Been trying to search and find some answer. Doesn't seem to be much info on this and sifting through the ones that say problems were brakes or diffs (since yours is all 4 tires and even in 2wd i wouldn't think these apply). I have found one possibility. The t-case chain has stretched and is binding or trying to skip a tooth only in reverse.

Alright, i'll keep looking for more info.

[bigjim350]

Something loose and binding in the Tcase would be my guess. No worries though just run down to the junkyard and grab another for a couple bucks :D :p

[cantab27]

could be brakes ......has crossed my mine, thought it was until the bang noise why trying to drive through the lock up.....the four wee skids are the wheels skids / dragging why the power is on until it bangs free,,,could be brakes as they are shit at mo so may be tied in to it all.......have spare rear 44 so it wont be that..lo

Brakes were my first thought till i read about the noise but also it would have to be the central part of the system, my wording for the booster/master cylinder/pedal. Since it was all four tires and was in 2wd i can't think of a logical reason a problem with the individual brakes could lock all four.

i hate you.............:D

[cantab27]

yeah thinks its gonna be tc.......found one for $350.............will wait untill i get it to my mates shop...

[cantab27]

oh yeah ..can push it back in neutral and it does it.....

[ArmyGuy45]

If all 4 wheels are locked up, how does it move?

so, how did you make those black stamps on road?

[4.3LXJ]

Doubt it is brakes mate. They probably don't work that well when you want them to. Check that linkage first. Small theory here. Something shifts in reverse enough to cause it to try to engage into low range, but not all the way. Try disconnecting the linkage and then back up.

[xj4life2]

Wayne, I would do the following to isolate the issue
1.disconnect the front driveline and test
2.replace front and disconnect the rear and test
3.disconnect all linkage(transfer case included) and manually put it in reverse and test, then reconnect the TC and test.
This will isolate the area of issue,I saw this once before and it was the spider gears in the rear diff. binding and throwing the torque into the tc. The one we had was rear end but front would do the same.Bad bearings also could cause this.I dont think its in the case, but it could be , I thnk the pop in the case was just torque transfer. Do you still have 4wd going forward? have you tried to reverse in 4wd? same issue ? Hope this helps a little anyway. If you have a lift you could put it up in the air and run it backwards and listen for noises and look for binding.

Why would all tires lock/skid then? Since its in 2wd and if it was something in one of the diffs shouldn't the other diff be separated.

They are all tied together by the drive shafts even if the front is not locked in the shaft still spins.If one psrt of the system is locked up or binding it would cause all to drag or skid . By removing the shafts one at a time and testing you can eliminate the frt and rear diff.

Ok, then i'm out. That opens up too many possibilities for me to be any help, good to know though.

Good luck Wayne.

[cantab27]

still have 4wd and does it why in 4wd....will try some of these things tonight after workies...

cheers

[cantab27]

Thats where "them" jeeps belong :D

[cantab27]

Thats where "them" jeeps belong :D

never a truer word spoken...........:p
















ps ...still hate ya:D

[cantab27]

well drove it off trailer and started binding from the front....so took the cover off the little d30 and found this...

http://i469.photobucket.com/albums/rr52/cantab27/v8%20tj/SAM_2442.jpg

pin has snapped chewing the spider gears...pin was falling out at random times ..so there for lockup was random.....but getting worse..chrome molly axles mmmm..so this may be the next weakest link......or just old and abused :rolleye0012:

anyways have a zj lsd one for it...so not a biggie.....:D

[4.3LXJ]

Did the roll pin break. Might want to check that and see if it was there in the first place.

[xj4life2]

Set of spidy's and a new roll pin and your good, Heck you can do that in the vehicle. Glad ya found it wayne !!!!
Barbie Jeeps :bang:

[4.3LXJ]

Or how about an Aussie locker. It has a new pin in it :D

[cantab27]

lsd outta a zj going into day,,,,,,pin has snapped will get better pics when i pull it down

[cantab27]

http://i469.photobucket.com/albums/rr52/cantab27/SAM_2462.jpg

well i dont know what to do.....pull diff ,plus the spare only for it to dawn on me that i dont run stock gears...ive got 4.11...so getting that nice smell of
diff oil over me for nothing:mad:

what to do next....:(

beef the gears up if i can..locker or ???????

this can only be fixed by me purchasing something.....and that hurts me down here......

what a thoses cable lockers like i have read the odd posts about......

cheers

[XJ Wheeler]

Whew, tough luck mate. Looks like a good time to source a stronger axle, maybe one that came with 4.11s to save cost.

[cantab27]

this is what i think tony and queried a bit back...i'm running chrome-molly axles so the weak point has to move...gears be it...??

[4.3LXJ]

Hey mate, tough break. But all is not lost. If you have 4.10s, you can use a whole axle out of a 4 cyl XJ or TJ and save the set up. They never have any wear on them like the rear. The cable lockers I assume are the OX Locker. Work well, but the cable is a PITA. Same cost as an ARB, maybe more in your part of the world. Lunchbox locker would be easy on a stock four banger axle

lol dont get the 4 bangers down here steve......can ya get chrome molly gears ???????? gonna do home work for a bit on this one...

[4.3LXJ]

Chrome molly gears. Nice idea, but already thought of. The alloy used is tougher than chrome molly. And hardened too. Try taking a file to then and you will see what I mean.

But, I couldn't quite tell from the pics how bad the damage was. But as I was driving my "Superior Jeep" :D to town, I was thinking if the damage was only to the ends of the gear teeth, I would just smooth them off and call it good. Not much strength there on the edges anyway. The center is where the most strength is. How is the carrier? That hole for the cross pin damaged?

[cantab27]

the whole thing is had it....will get more pics of it........whats peoples thoughts on these lockers........

http://www.quadratec.com/products/16100_4502.htm

wanna fix it but do it right and i think locking it may be the wat to go..?????

http://i469.photobucket.com/albums/rr52/cantab27/SAM_2461.jpg

[4.3LXJ]

Supposed to be a good locker. You get a nice tough diff cover in the deal. Only down side is cable, like what to do with it and in a front you have to steer the wheel back and forth to disengage. Add cable and shift lever to that price. An extra $189

[cantab27]

still be cheaper than arb..by the time ya got compressor and such..... and again everyone runs arb down here...I'm different hence the jeep thing lol'''will keep looking for reviews on the ox...anything on ya other forums Steve post in here..thanks mate..

[4.3LXJ]

The only issues I have run across is the cable thing. There is an electric solenoid kit available so it will work like an E Locker. A little spendy, but it goes on the diff plate. Only down side to that is it needs to be shielded. It is very similar to the Toyota factory rear locker set up except it is on the diff plate instead of the carrier.

[4.3LXJ]

Wayne, did a little research but couldn't find much on the electric or air actuation system they have. However I did fine that the Diff Shop in ChCh is a dealer. But you knew that right?

[cantab27]

cable / air hose still gotta be plumb up somewhere.....the ox also has this


http://www.quadratec.com/products/16100_4403.htm

will keep looking ...will get on ebay and have a lookee

the ox would be around $500 cheaper to land here me thinks....

[4.3LXJ]

Very true. If you wanted to lock it for the day, then that would be great. But I gotta tell ya that a completely locked front end does not steer well. That is why a selectable can be better than the other types, particularly a welded axle. But it is a good fail safe.

[cantab27]

think that wee tool will let you unlock diff if ya damage the cable why wheeling..kinda like a fool safe thing..that's why i'm looking at selectable lockers for front.....steering ....dont need it locking up on the street...

Not sure mate. Looks like it will lock by pushing on the fork, but it doesn't look like it will pull. But hard to tell for sure.

[4.3LXJ]

ARB of course says they are not as strong. Might be something there, but after seeing the testing done on them, not an issue for 33s in mud. Tests done with 35 spline alloy axles. The whole thing was at the point of breaking. I am sure these will outlast 27 spline axles alloy or not. I used to get a discount there, not sure if I can now or not.

[cantab27]

will email them during the week re with price with shipping ,.......got a nice warranty with it...

[4.3LXJ]

Very good people to deal with
