At the front of the propshaft there is a large rubber coupling on the front universal joint, these become soft with age and can cause driveline vibration, check it by gripping the prop at the front and try to see if there is exessive movement, if yes then change it.
It could be the centre rubber vibration damper but i would go with the front first.

is it on picture marked with red arrow?
found on Ebay

is this that rubber?
My car is omega 2.6v6 2002.y.
-
YEP,
but the one one ebay you linked to is used and therefor unknown quality, also it does not list its model fitment as to what what engine size. they might be all the same but you will have to check that with your local dealer. if you fit a used part you might end up doing the job twice.
Some parts you need to buy new. More informed on here will be able to help you as to poss variations in part no and fitment.
-
I can't find GM number for my Omega 2.6v6
on ebay and local store there is only for 2.5v6 with no. GM 90578558 and swag 40860002 (50x127-131x30)
does it fit to my Omega?
-
Take that part No to your local dealer and ask if they are the same across the range.
-
rubber is OK but some disk is not :(
can I change only this disk? if there is a GM no.?
-
What disc are you refering to, need more information and discription pls.

I found
it is PROPSHAFT BALANCE WEIGHT GM 90522611

is it possibly to repair, what can go wrong with it?

is it possible to drive without balance?
preice for new is about 600 Euro and can't find replacement
-
What makes you think yours is faulty mate, is yours damaged in anyway ? as far as i can see there is nothing to go wrong with the balance weight, have you checked the prop shaft to see if the small balance wieght is still attatched to the propshaft. It is a curved piece of metal stuck to the prop half way along its length, if that is missing it could give you the symptoms that you describe.
-
Does the vibration change at different speeds and does it occur at a certain speed, and dissaapear at a set speed.?
-
i have this strange vibration on my 3.0 mv6 seems to come from the prop but only does it when backing off the gas between 60 mph to 50 mph but if i dip the clutch it stops it
-
it occurs only in 1 and 2 speed entering and exit roundabout, or when uphill start and turn left or right
when it happens reducing the acceleration it disappears
when accelerate straight and at higher speed there is no problem
-
i wonder if this is more related to the diff half shafts rather than gearbox, propshaft, coupler.
From the discription sounds like the shudder is when the car is turning either r/l and underload
so could be the joint on the half shaft.
Does the car have a LSD DIFF?
-
don't know about LSD diff
and don't believe that balance weight is wrong
what You mean by joint on the half shaft???
-
from the rear diff on either side of the car is a drive shaft, and at each end of the drive shaft is a universal joint with a rubber gaitor on it, these are the joints that allow flex of the suspension whilst the car travels forward and the suspension travels up and down.
Check the condition of these joints for slopyness and also the rubber gaitors for splits and tears, if split then the grease may have leaked out and road dirt and salt may have entered the joint and caused damage.Other than that then I dont know how else to help you, perhaps someone else may have an idea.
-
Have you checked wheel bearings and wheel nuts for correct tightness, also worth checking conditon of front wishbone bushes and lower swivel joints as well.
-
1th mehanicar suspect to universal joints and lose clamp on rubber boots and oiled it. No difference in vibration but I think it could bee problem, will check again
all wishbone bushes (4 front and 2 rear) are new

Find cose of vibration
It is up wishbone bush on carrier of diff

-

no, it was not wishbone bush.
problem was some plate in diff, don't know name but here is pic that i found on net (not from Omega)
(https://lh6.googleusercontent.com/-TflXXERGFkQ/ToT4QB6tiiI/AAAAAAAAAwM/BRa8KCPfIEU/s640/86.jpg)
seams that the plate is acting as spring and after time of usage is aligned
on the press we warp out centre
now i have no vibration, but don't know how long it will be OK
on the automotive hoist
before > when turning one wheel other one was standing still
now > when turning one wheel other one is turning in the same direction
think now I should have better traction, will know after few days testing
