Haha I needed some humor today

 

You don't have to take the diff apart to change the output shaft seals.
Just remove the output shafts, they are easy to remove.


IMO the whole axle, from wheel hub to output shaft, "floats".
Splined at both ends, one end in the wheel hub the other in the side gear (inside the diff)
At the hub its tight because of the axle nut, but inside the diff its not supported by a bearing.
The bearings you are talking about are the Torsen bearings IMO.

Replacing the Torsen LSD bearings is not that easy and you'll need a good puller to to that.
And you'll need the proper tools to put the new bearings back too.
Besides, IF the Torsen bearings are worn your gear set will have taken a beating too.
If the Torsen moves, the ring gear moves, backlash is changed, etc..

Who installed your 4.57's?
What kinda diff oil did you use with your 4.57's?
A higher final drive ratio is a bit harder on all axle parts.
Are you lowered?
Lowering wears out your CV's a bit more as they operate at an angle almost all of the time.
(this combined with 4.57's and a spirited driving style...)
Swapping inner CV buckets is an option.
Spacers may just give you a "fresh patch" inside the bucket but don't change the angle the CV is operating on.. just my opinion on that.
Your output shafts may be worn, where they enter the diff.
Or a combination of all of the above.

Because he wanted to replace those bearings, is why I said clean it up and inspect the gear and ware pattern. That is something that anyone can do. The problem is, few can read the pattern or ware. That is where the pictures came from.

He is chasing sound in the rear and has done everything on the outside of the diff and is working his way in. So logically if it is the gear, opening it up and inspecting it will surely tell the tail.

Is there anything in my post that "undermines" what you posted?

 

Thanks for your help guys. Here's the prob- I went to Honda almost exactlya year ago (18k miles)for a recall and asked them to change my diff oil. They charged me for a "diff overhaul" without my knowledge where they replaced the seals for the out put shaft and put two $7.16 bottles of fluid in. That msrp is right around the cost of the CRV fluid. I'm guessing that is my culprit? I've changed my game plan and I'm waiting to see what Honda has to say about it. My friend has a spare diff from an '05 with 25k miles at his shop if all else fails.

 

Btw, my neighbor is a retired mechanic (NASCAR/Chevy guy) and he gave me a hand inspecting it, again ON THE CAR. He played with it for about 20 minutes and scratched his head saying somehow it feels like the gears are ok, and asked me if I changed them out for something aftermarket. I told him Richmond, and he keep saying how great those gears are, and how he used them on his Camaro, etc. Stratocaster- for a great product.

 

Update- called the Honda dealer and they said even though my invoice said they replaced the seals they didn't I asked about the fluid and they said they put the correct one in. Even though I had their sku#, he said he couldn't look it up on the computer but "they put the right oil in the car."

 

I find it strange that they list TWO bottles of fluid. The differential in the S2000 takes less than ONE quart of fluid, the only gear oil that I've seen for this car comes in 1 quart containers. Why were you charged for two? Could they have been talking about the transmission? Or are they using some weird sized bottles that hold less than 1 quart of fluid?

I'd be googling those SKUs like crazy if I were you. Something isn't lining up here.....

It was your first sentence that lead me the direction I went. But no nothing underminded anything.

So let me get this straight: The dealer charge for and did not work some service work? Swapping the pinion seal risks the gear installation and they just did it (Not really but, that is another story) without your knowledge? And now they want you to take their word for the fuild they put in?

IMHO drain it and send a smaple to blackstone. See if they can ID the oil used. Then fill it with something that is known to be right. Have your neighbor help you. Give him a beer, and ask him to talk you through it. Also do it on a Saturday becasue NASCAR runs on Sundays
