Please help... bad diff?

[c00nhunterjoe]

I listened to the video again. Sounds like a ratcheting sound, not a whine. I would drop ghe shaft as has been suggested prior and rotate the pinion by hand. Did you spin it over before installing it?

YEP !
Get that Driveshaft OUT and rotate by hand again !

Ill do that tomorrow. When i was installing it, i did turn in by hand before installing the driveshaft, it moved freely.

Ill check to see any play tomorrow. Is there a way to get the yoke part out and replacing bearings without removing the diff? It takes me 2-3 hours to remove the diff, and another 2-3 to put it back. And like i said, the one place im gonna take it to, charges $385 to just take it apart...

It is not a whine sound.

Update*

I have squared away with the seller (charger-bodie). We have come to an agreement.

The diff is in the shop, parts are ordered, hoping it will be fixed by next week.

That is good news.

Great, buying second hand is always a risk, your probably lucky Charger-bodie stepped up, allot wouldn't.

What parts were ordered by your shop? They havnt even looked at it yet? That videondoes not sound like a bearing. I fear your quoted price is going to be significantly higher once they have possesion of your rear.

From your other post, the diff is rebuilt. Did they give you the old parts back? What component did they say was bad?

Sorry for long wait on reply

So, the only parts i got back after rebuild was the gears, and the long gear on a stick (sorry, dont know its actual name) had some teeth that were badly damaged.

Right now there is no bearing noise, but i do get some howling sound at highway speeds, but only in certain driving conditions which i cant pin point. Wish i had a good garage to work in and more knowledge...

[c00nhunterjoe]

Gear on a stick is the pinion. How did teeth get broken on it? The whine you are describing now, if it changes based on whether you are coasting, light throttle or accelerating, then its from the ring and pinion being set up incorrectly when they rebuilt it for you.

Check front to back pinion play, If detected (any) you might install a  new crush sleeve and see if it helps. $10 dollars and an hours time.

He just got it back from being overhauled.
