Vibration when accelerating

i'm not qualified to assess the diff. just making a guess.
it would help if you could guess the location of the vibration.
when the cv joint vibrates, you can obviously tell it's coming from the rear of the car.
can you guess the location of the vibration?

I would say it's quite ceratainly from the rear of the car. The car is going in to Honda for a standard service on Thursday, so I'll tell them to check it then. But it would also be good to be able to point them to what it COULD be. IF it is the diff, would it be the final drive gear? (That seems logical to me at least.)

You're also sure it's only vibrating during acceleartion?
Parts to check are (IMHO)
Trans output shaft.
Trans mounts.
Propshaft CV's at both end.
Propshaft length compensator (sliding part at IIRC the diff end).
Diff input shaft (if you find play up/down or in/out there its really bad)
Diff output shaft.
Diff mounts (front & back)
Inboard CV's.
Outboard CV's.
Wheel bearings.
Btw.. what does the "level 2.9" mean?
They look like OEM CV's and axles.
About the diff output shafts.. they are not really supported by bearings.
The output shafts "float" so a little play is normal.

More info about the axles here: http://www.driveshaftshop.com/pdetail.php?pid=708 
I can only feel it when accelerating. If there is any vibration at all with constant speed/throttle, it is extremely mild. Could it be the gears in the diff?
I am not the best in all technical words and terms in English vs Norwegian... I am very greatful for all your help so far! Could you help me and confirm/correct me here?
Trans output shaft. Parts catalogue picture 2 part 6?
Propshaft CV's at both end. Parts catalogue picture 4, circled red?
Propshaft length compensator (sliding part at IIRC the diff end). Parts catalogue picture 4, circled red?
Diff input shaft (if you find play up/down or in/out there its really bad) Parts catalogue picture 1. part 1?
Diff output shaft. Parts catalogue picture 1, part 2?
Inboard CV's. Parts catalogue picture 3, part 5+6?
Outboard CV's. Parts catalogue picture 3, part 5+6?
Again, thanks a lot so far!

About the Driveshaft's description of their axles:
Your inboard CV's look 99.9% like OEM's, the outer shape of the CV, the flange and the diameter. (just painted black
)
This means IMO the tripod is also the same size.
As far as I remember OEM tripod wheels have needle bearings, I have a picture at home I will post as soon as I get home.
Anyway...
Trans output shaft. Parts catalogue picture 2 part 6?
Yes, with part 7.
Pull & rock the flange to see if there is any play.
Propshaft CV's at both end. Parts catalogue picture 4, circled red?
Propshaft length compensator (sliding part at IIRC the diff end). Parts catalogue picture 4, circled red?
Yes, the length compensator may have little play but not too much - hard to tell online.
CV's should be without play.
Check for grease marks on the chassis.
Diff input shaft (if you find play up/down or in/out there its really bad) Parts catalogue picture 1. part 1?
Part 1 is the flange but yes.
Pull & rock to check for play
Check for oil leaks.
Diff output shaft. Parts catalogue picture 1, part 2?
Yes.
A little bit up/down play is normal
Also check for oil coming past the seal.
Inboard CV's. Parts catalogue picture 3, part 5 + 6?
Just 5 on both ends.
Check the booth for tears
Check the straps
Outboard CV's. Parts catalogue picture 3, part 5+6?
Just 6 on both ends
Check the booth for tears.

Thanks a lot! I changed the axles because of pitting in the inner CV joints. The prices on parts are insane here in Norway, so I got the pair of these axles for less than i would have to pay for the CV joints only in Norway. And again, thanks. I really appreciate it!

What somewhat bothers me is that aftermarket manufacturers sometimes "dish" OEM parts by using incorrect info.
OEM is not that bad you know....
I hear you about OEM Honda parts price in Europe.
When I need stuff NOW I use the dealer but if I can plan ahead I'm buying OEM overseas (Hard Top Guy)
With shipping & import tax its still cheaper than buying at the dealer.
In the case of axles, lower arms and stuff... I donno.. kinda heavy.
It makes you wonder: driveshaftshop sells you new OEM parts & OEM quality with a huge discount?
I don't think so.
Keep us updated on what you find.

Hmmm. Now I'm getting really frustrated. Had the car at Honda today, and I will say that just about everything is checked without finding anything wrong. Axles, diff and all "joints" in and out, propeller shaft and connection points, wheel bearings, engine mounts, transmission mounts and diff mounts. Found nothing wrong. So I'm really clueless now...
