Vibration in 3rd
For months now I've been battling with a vibration at the rear, and thought I'd beaten in too, so any advice would be very much appreciated here..
Symptoms
Vibration, when under load in the vtec. But only really noticible in 3rd gear.
I left the car with TGM a few weeks back, and the best guess was damage to either wheel or tyre. This rang true as s year or so ago, I had a similar vibration which was indeed cured by replacing the rear wheels.
But confirm this, Tom put another set of rear wheels he had on the car, and said there was marked improvement.
I then went away, sourced a set of wheels and tyres, and put them on yesterday. This has made no difference to vibration. Again, there is nothing discernible through first and second, even when pressing on, then hit the vtec in third and it starts to shudder. Easing off the gas, but maintaining the same road speed, and the vibration dies away, which suggests to me it isn't a prob in the wheels or tyres, as its only under heavy load.
More curious still, is that continue on and 4th doesn't present anything like the same vibration.
I'm at a loss. Could there be something wrong with the gear itself!??

does seem strange but could just be apparant most at that speed, worth a try if you've got a spare set of discs knocking around. I know when i had a wheel loose on the back it was more obvious at one speed...went faster and it'd stop. could also be a sticky rear caliper.

Mine felt like yours under heavy acceleration, especially at higher speeds (i.e. 3rd gear Vtec)
The vibration went from 'hardly noticeable' to almost undriveable within a couple of months.
Swapped inner cups from side to side which usually cures the problem (search for threads on CV cups) to no avail, but eventually traced it to outer off-side CV wear.
New shaft fitted and puurrrfect again!

Also interestingly, is that 4th gear doesn't show the symptoms either, either at 3rd gear vtec pace or in the vtec itself. Its been a while since I've been in the vtec in 5th to know if that pattern continues..
I'm guess fitting new a shaft (drive? tail? prop?
) carried a not insifnificant cost..
