HELP!! I think I broke my Jeep 4WD'ing today?

[AussieJeep]

Hi Guys,
Went 4WD'ing on the beach today (for the first time) and basicaly gave the Jeep a gut full and I think I broke it?
This is what happened:-
Got bogged in really soft sand, finaly got out (with a lot of help).
Whilst changing from low to high gear range (4WD) heard a huge clunck noise and thought, Shit what was that?
Car went great after that - no drama's.
Got off the sand and onto bitumen road home.
Drove for about 40mins then all of a sudden the car starts making this clunking noise with every wheel revolution. When braking the sound would dissipate.
Pulled over to see if there was something stuck in my wheel - no.
Limped the 10KM home and my mate had a look and thinks it's got something to do with the 'transfer case" cause when I try to rotate the drive shaft up the front that goes into the transfer case it makes the same noise?
Any ideas?
Anyone had the same/similar problem?
Is it going to cost me shitloads of money to fix?
Thanks.

I dunno mate

you still under warranty

get on to www.ausjeepoffroad.com

could be diff, Cv's

which part of Aus you in?

 

[AussieJeep]

Hi Fouros,
In Newcastle, NSW.
Out of warranty.
Thinking it's the transfer case or front drive shaft as there is a fair bit of movement in it.
Just done a search on the other posts on here under "transfer case" to see what comes up. ](*,)
Figuring I'm gonna be up for 3 grand - worst case?

 

[fouros]

if it is your t/fer case or drive shaft

try here

they advertise on Ausjeep and from all reports they are a good bunch

Thanks Mate!
I was hoping there would be such a place in OZ!
Cheers.

When i get her fixed, I'll post some pics!

 

[fouros]

not a problem

check out ausjeep when you can


we are slowly building an Aussie Kj community over there

were you moving at all when you switched from low to high? Where you in gear or in neutral? Hard to say exactly whats wrong, but it does sound like something is wrong.

hmm, i really to not think its something that major. Unless u were in low doing 30mph and shifted it in2wd or something like that, ur tcase should be fine. If it does it with every wheel rotation then theres no way its ur tcase, the drive lines does not turn at the same rate as ur tires, they turn much, much faster. Put it up on some jack stands or something and get under it and turn things and see what u find. The front drive line does have alot of slack in it, thats normal. I am thinking it make have something to do with ur brakes or the "front drive train". Maybe bearing, cv jonints, something like that.

It sounds to me like the transfer case failed to release the centre diff and it was all locked up. they advise in the handbook to do a neutral shift and if you get a bit of lock up to stop and reverse a couple of feet to take the strain out.

 

[JeepJeepster]

then why did it go away when he hit the brakes?

 

[Derek Mc]

there would be no loading from the engine so there would be less noise, it does sound as though there is a problem possibly caused by driving on tarmac with the centre diff lock engaged for that distance, It happened on a mates import CJ many years ago, that was what was diagnosed, but hey? Lets hope its simple simple cheap cheap, these are tough little things \/

 

[JeepJeepster]

Well, i wonder if it does away when he lets off the gas too? If it did then i would understand it being the drive train. But if hes off the gas then hits the brake to make it go away, idk.

Would like to have ur crd though. 8-[

When you are on the road and the clunking appears...are you in 2WD or 4WD.

Does the sound change with this swap?

Check the U/J / knuckles....These are a weak point on 4x4's with a bit of power when you load them up...

The U/Js on my Mitsubishi Shogun were consumable items!

Hi,
Yes the car was in nuetral when I was changing from low to high. When i got bogged, some guys pushed us back down a steep hill and they said the car WASN"T in 4wd when it was. It was like the front 2 wheels hadn't engaged or something? Changed from low to high again and it seemed to engage.

I did a search on the forum and it seems there is an inherent problem with the KJ not engaging the 4WD gear change at times? The was one occasion yesterday, where I did change it (stopped and in neutral) and it made a huge bbang noise. I have since learned that this is a common thing and I probably didn't"break" anything then?

Car was in normal 2wd when driving on the bitumen road home.
Thunking noise happens in normal drive and I put it in 4WD last night and it still makes the same noise. No change when swapping.

Accelerating, the car makes the same noise - just faster!
Braking, I can't hear it when the car slows a bit?

Will make some calls in the next few hours to see what I can find out and let you know.

Cheers.

O.K PROBLEM FIXED!!

I'm a bit embarassed to tell you what the problem is ](*,)
It turns out whilst going over some very big "jumps" 4WD'ing, I have snapped a wheel stud, the other 4 nuts loosened (?) and the wheel was about to fall off!
This would explain why the thumping noise would go away when I put the brakes on. It would stop the disc from vibrating etc.

So fortunately I don't need any major transmission work done \/

Took the mechanics a while to work out what had happened.

Thanks to all your responses =D>

 

[fouros]

thats good to hear

at least a stud is not as expensive as a t/fer case =D>


did you get on to Ausjeep there is a few Kjers down your way, and you can get info on the Jeep jamboree next year

 

[AussieJeep]

Not yet, but I will be sure to check it out.

BTW, how do I put pics of my car in a new posting?
I tried today to just upload a pic from my computer through profile and it said it had to be .jpeg file or others, and it was ajpeg, but it wouldn't work?

I have seen people put postings on here and big pictures of their cars come up and I want to know how to do that? I saw yours a while back when you were 4WD'ing.
Can you tell me how to post them (Aeh)

Cheers.

If you snapped a wheel stud, it is likely that they were all loose to begin with. Check back in time to see to who last worked on the front wheels or front end. :-k
