Replaced axle bearings, now the howl is back

Replaced axle bearings, now the howl is back I had a howling while on the highway so I replaced the axle bearings and seals. The driver side axle was also chewed up so I replaced it as well. Put it all back together, and what a difference, it was quiet again!
But... it didn't last. Now I am hearing a howling yet again, after only a few hundred miles. It is a little different now than before though. It used to just be speed dependent, the faster I went the louder it got. Now it is the loudest when I am accelerating or climbing a hill, and it gets fairly quiet when coasting (though it is still there to an extent).
Could this just be a dud bearing? Or could it be from something else in the drivetrain? The car has almost 125k on it right now, though I have a suspicion the rear may have been rebuilt at one point (c-clamps are gold colored possibly from heat and the little bolt on the carrier had a good wear mark on it, but the gears don't look like they have 125k on them at all).

Too loose of a bearing preload?
You should have to dead blow hammer the carrier into the housing.
If its louder on one side, sounds like gear setup to me. When you replace the carrier bearings, you have to check the patterns cause they will move. Sounds like backlash has changed from what you described.

It can harm it but im sure he doesnt have super huge chunks floating around in ther either. Posi units with cluthes require metel deposits (friction modifier)to allow the clutches to grab. I would never put the friction modifier in my engine lol. whole nother concept. small amounts of worn parts in the rear is fine untill is wears so thin it breaks or increases the viscosity of the gear oil

When I changed the axle shaft bearings, I swabbed the axle housings out good, and cleaned out the pumpkin. There was only a slight bit of fuzz on the cover magnet.
Like I said earlier, the axle that was shot was replaced, and the other axle had no grooves or pitting.
If it is a carrier bearing I'm gonna
and maybe upgrade the whole darn thing to a Torsen unit. Except, I've never done anything with a differential or set up gears or anything. Wonder if my friend has.
*off topic* ahhwataday, your car in your sig looks great!

Hey man you can replace the Carrier bearing with no problems. But if it is required than you may want to freshen the entire rear. Well the carrier and pinion atleast. If you do, you will need some specialty tools. You can get them off ebay for around $100 or firends. Its pretty simple really. O1ssreda4 knows his shiit and has helped me a bit. If you got guts do it haha Ill help you out.
May want to change units and gears
*Thanks for the sig comliment. She is sold now im building the Rear for the Black Camaro
hahaha I have built rears. "oh whatever", stop actin like a baby. We are all here to help and learn. Ive got a 10 bolt im workin on now (and a 9 inch and 8.8). Look on here I even posted a question

If I do it maybe I'll replace the axle bearings and seals again for good measure. They're cheap enough.
What rear you putting in the black Camaro?

You have a 3.08??? You have a V6 or Z? A4 or M5 or 6. If you have an auto i would say go to 3.73 or 4.11. If a straight drive v6 go 4.11, straight drive with an ls1 I would reccomend 3.73. Yes of course you can go with higher or lower but I find these ratios to be pretty safe. with these cars. Also recommend a rearend girdle. TA, SUMMIT, JEGS, few others. Just a little extra protection.
Im putting the 10 bolt in the black one. I wanna do what cant be dont. "keep it alive"
hahaha. my tires will spin before i break a properly built rearend.
lol whatever homie. I said, "I DONT THINK THE SHAVING....". This would mean that your explaination could be true. I didnt say "you are wrong, please dont post in here you stupid idiot" lol.

Yeah 3.08 open diff on my V6, currently A4 but will probably end up manual, either T5 or perhaps T56 (watching a thread on FTV6 where someone is gonna do that, curious how it turns out). Turning this car into a project with a turbo setup and supporting engine mods. But that won't happen for a while. Future project!

Wait till you get a turbo. If you are gonna race stay auto, fun on the street and turbo get the t-56. T56 with the stock v6 will be rough. On the highway You will be goin from back and forth from 6th to 5th.
With your future plans I would say get a 3.73 or save a few bucks and get 3.42. Me personally, 3.73. But ists up to you. Keep an eye on ebay and craigslist for a posi unit. You can go to 2 series and get everything sheaper too. You could find the ring pinion and carrier.
