Alright guys it all started with a clicking coming from the front wheels so under further ivestigation i put it in 4WD and locked the hubs to hear a bad clunk like something is binding, so i then unlocked the hubs and drove it in 4WD and the clunk went away, so i thought it was the birfield, i took the axle apart, and everything looks fine, birfs wheel bearing everything, so where do i look next? im thinking its the diff but i dont know where to start first? has anyone ever had this problem before? Thanks guys

Pull the driveline, lock the hubs and see.

i pulled the driveline and it seems to me that the cv joint is binding so i took it to the driveline shop they said theyd let me know by tomorrow ill keep everyone posted as to what i find

DId you drive it the same way it made the clunk, without the driveline?

GONZO97 · « **Reply #5 on:** Apr 28, 2011, 05:42:33 PM »

yes and nothing, im thinking it has to be the driveline for sure, unless its the transfercase, but if its the transfercase then it only does it under load

Could be the centering ball, they fracture and bind causing a nasty clunking noise. Just replaced mine for the same symptom.

Hope that's not the case I get the driveline back today I'm hoping that's where the problem was

I had the same problem just recently.
I had sheared 7 gears in a row of the ring gear. It also had large chips in other places on the gear.
I guess anything can happen when your crawling.
this is where i think your problem is.

My truck is solid axel swapped. I don't think it's the ring gear no chunks of metal when I drained the diff

was there any glitter in the oil?
you might have taken some teeth off of the birfields?

GONZO97 · « **Reply #15 on:** Apr 30, 2011, 06:58:14 PM »

when i drained the oil it had some metal deposits in it but i checked all the teeth on the birfields and they were absolutely fine

GONZO97 · « **Reply #16 on:** May 01, 2011, 10:22:13 PM »

just a little update today after finally being able to get out of bed(wisdom teeth got pulled) i was able to hook up the front drive line again, due to my disappointment the clunk is still there, which i feel only leaves one last place to look, which would be the front diff, if the problem is there then im most likely just going to start my regearing process of front and rear, doesnt make sense to pull everything and regear later on

GONZO97 · « **Reply #17 on:** May 02, 2011, 10:48:51 PM »

Guys I finally tore into the front diff and look what i found,

and the teeth that got chewed off

....

so its time to start regearing, going to go with 5.29s, so while i was at it i pulled the rear diff which is a v6 but im not exactly sure what its supposed to look like,
is this right ? or is there a limited slip in there?

Rocksurfer · « **Reply #18 on:** May 03, 2011, 02:40:10 AM »

Oh, ohh, pinion was loose and dropped on the carrier. I had that happen on my 84, sucks if you'd have caught it early you may have saved it. Mine was the rear, I also regeared at that point and dropped in a couple Detroits to ease my pain.

GONZO97 · « **Reply #19 on:** May 03, 2011, 09:07:18 AM »

thats what im planning on doing regearing all the way around to 5.29s and then im looking for an affordable locker for the rear hopefully i can find one so i can just do it all at once

superyota · « **Reply #20 on:** May 03, 2011, 09:51:30 AM »

time for an aussie. go with a solid spacer when you rebuild the thirds. you won't have to worry about the crush sleeve getting messed up if you hit the drive line on a rock.

93REDCRAWLER · « **Reply #21 on:** May 07, 2011, 12:01:26 PM »

I told you my bro.
i Guess sometimes you just got to learn for yourself.
look at those teeth you got out of there man.!

well when i drained the oil no teeth came out , then we pulled the diff and sitting in the bottom (where some extra oil sits in the housing) were those big chunks, oh well, tonight i am setting up my 5.29s and my lockright so tomorrow it should be back on the road, regeared and ready to rock

This is how i found all my teeth when i messed up my diff. same thing you got no huge chunks coming out the bottom but when you tear into it then you find the problem. Well I'm glad you figured it out and hope everything else works out for ya.

Looks like a stock v6 third member to me. They are so often mistaken as LSD just cause they look B.A.
