What i really want to know is why after putting in a good straight axleshaft that the rear end all of a sudden is making noise? It starts around 15mph and goes throughout the full range while city or HW driving. It DID NOT do this before but now it does? Ill have to check the end bearings and see if it is coming from them but in the front seat it sounds like the Pumpkin.

Also: if i can get the carrier and gears from the JY for cheap can i just pop them in? What would that entail?

Just call it a day and spend $150 to $200 on a 1997+ Chrysler 8.25 from a JY. You won't be chasing down this whine or worry about these damaged parts. By the time you're done throwing money at your wrecked D35 you would have already bought a new rear end from the JY.

"and that threaded disc thing and had a hell of a time getting it back in right. The bearing that from what i can see it rests against wanted to push it back everytime i tried to screw it in more."

that's the problem rite there!

you don't remove that to replace the axle shaft.
now if it's not too late (for the bearings and gears) you need to have the backlash/bearing preload adjusted now by someone that knows what they are doing.
no more driving until it's fixed.

Um it popped out when i loosened the c clip and at first i couldn't figure out WHAT it was until i asked my old timer neighbor and he said to put i back in, screwed all the way tight.

How is the backlash adjusted on that particular peice? Chances are i can get it to a axle shop later today

There's your reason for the howling/ whining noise. I suggest start looking for a '96+ 29-spline 8.25 out of an XJ with correct gear ratio. If you want to go the other route and have the bearings and R&P replaced and set-up, you're looking at something in the region of 500+ for the parts + work. A good condition JY axle shouldn't be more than 200-300 + new u-bolts..

Im going to try and properly torque the lockers for the carrier and failing that then i will go and find a good replacement. Either way ill be out a couple bucks for the rod and 36mm knut and maybe i might find a way to put on my 4.10 geared Dana 44s off my old Comanche. IF that would take an afternoon without major modding that is.

Oh, crap I didn't notice there was a few more new posts on the second page when I posted...damn mobile- phone browsing

Yeah, you shouldn't have removed the carrier bearing setup-/ preloading screws. If they popped right out when removing the c-clips and shafts, you already had a major problem with the axle. That is also the reason your carrier bearing setup is now all screwed-up.

Also, your neighbor was all wrong with the info on screwing them all the way in. They need to be adjusted by checking the backlash/ gear pattern on the gears. You need some special tools for addjusting gear patterns (a dial gauge and an adjustable magnetic clamp for it). Do not try it without them!

Chances are, because of the big play on the carrier, the bearings and gears are already destroyed by driving your Jeep. How much driving did you do with the bad bearing setup?

..actually, I don't even get it how did you manage to remove those threaded adjusters in the first place? They are located between the axle housing and the carrier bearings, so they should not come out without removing the carrier itself.. did you remove the carrier, and if so, why?

I never removed the carrier, i did the following in this order:
removed the bolts on the c clip, pulled the clip, went to pull the axle shaft, heard a metallic clank and in the catch pan was the adjuster. Had no idea what it was so when i put everything back together i just put it in as much as i could by hand, then used a hooked peice of wire and got it to spin in a bit more.

As for the gears being trashed, they look beautiful. like there is no visible wear on them anywhere which confuses the hell out of me being that it is the origional axle with 170,000 on it

There are NO bolts on the c-clips, they are held in place by the carrier center pin. The only retaining bolt you need to unbolt from inside the pumpkin when removing shafts is the very small (1/4"?) center pin retaining bolt on the carrier.

Look at the picture, the center pin retaining bolt is shown (which you need to remove):




Then you can slide out the center pin to have access to the c-clips. You can see the c-clips in this picture on the inside of the carrier, hanging slightly loose between the small pinion gears at the ends of the shafts:





Now, if you look at the above picture, one of the carrier bearing adjuster locking plate/ nut is at the very right of the picture on the carrier bearing cap. The other is not seen, it's just out of the picture to the left on the other bearing cap. If you do not remove the bearing caps and the adjuster retaining bolts, there is no way the adjuster ring should drop out when removing the shafts?

If the gears are ok, then they may be re-used. Anyways you gotta take it to a shop to have the bearings replaced and the gears set-up. Could be cheaper to get that JY axle.

Gears last for a long long time, in many cases WELL over the age of the rest of the vehicle.

Somebody may have already said it in all these posts but those adjusters have to be adjusted to set the carrier bearing preload. The carrier cannot have any side to side movement after it is properly setup. It should have a tiny bit of backlash movement but that is all the slack the carrier should have.

Man...what a ClusterPhuk

I think he just needs to swap a new axle in. It's his cheapest option. Between us telling him what to do and look for, and him not knowing/randomly taking stuff apart.....PLUS the fact that he's getting rid of the jeep and getting a grand am soon....

Wash the hands....DONE.
