Default rear end vibration while accelarating

i know there are lots of posts on this and every post has a different solution. i don't know what to do. some say its the drive shaft some say the bearings are shot. i thought i put the wrong diff fluid in so i got it changed yesterday and nothing changed. i also checked the Axel nuts and nothing. what can i do now. has any one had this problem who can guide me the right way.

Some more information is required.

When did you notice this happening?
What speed is this happening at?
Did you changed rims/tires?
Is it coming from both sides or one?
what happens when you're driving and put the clutch down, does it go away?
What happens on Decel?

Volunteer as much info as possible please

drive shaft spacers fixed the problem with me
usually this occurs after lowering the s2000 after (x)amount of kms.

for me it was 120k, some people 80k.

the root problem is pitting of the half shaft buckets.

i installed my own spacers, lmk if you need a hand.

it just started last week
it only happens when accelerating not in first gear but u start noticing it when u shift to second, third etc.
haven't changed the rims or the tires... i have ap2 v2 rims on my ap1
feels like it comes more from the passenger side
when i put it in neutral it smooth as a baby's butt
my car is lowered

my car vibrates too when i am on the high way and push on the gas. dont matter what gear it vibrates the rear end. weird. dont really bother me that much although it is a strong vibration. i just think of it as a super exhaust.

the truth.

or you can swap your half shaft buckets, but that can be quite the job.

*facepalm*

dude, get that fixed.

i never really noticed my vibrations until a friend of mine pointed it out.
Now my acceleration is smooth.

my vibrations made me not want to accelerate....
