U sure about that? How does a drive shaft stay straight when it moves forward and over bumps???

 

Dude when you are wrong at least take the time to be sure about your point before trying to argue it. The differential is mounted in a rigid fashion to the chassis and does not move when going over bumps.

 

It may be your wording but I'm interpretting this as you meaning that "vibration at high speeds points toward bad CV joints". If this is so, then it's not quite right. It's more likely that the symptom of bad CV joints is vibration when accelerating under power.

Trust me when I tell you: When "SlowS2K" states that there are NO U-joints in the driveshaft of an S2000, this information is solid and cannot be proven wrong.

 

As for the squeak from the right front,mine did the same thing. Found it to be coming from the lower spring seat/rubber pad/lower spring coil area. I sprayed it with white lithium grease....never to return.. I don't know if you have the same culprit,but good-luck

 

Did you get it fix?
I've just bought a 03 with 33k miles on it, mine does it same thing. I got it balanced today and it's alot better now but still there @ 72 mph. The tires are brand new too. =(
What was the cause?

 

i think its your tires

 

Talk about bringing a thread back to life!!

 

have the same issue....suspecting bad inner CVs..... I'll change it out all together with the differential that I'm having rebuild, so we'll see what happends.

 

I think it was the tires, but it's been so long I can't be 100% sure.

Maybe those with vibrations should start a new thread that's more specific to your issues.
