Shaking at 40kph and 60kph, 1,500rpm?

[Petronas]

My mate just bought an 2003 Accord Euro Luxury and we have noticed something peculiar after driving in it for two or so days.

At about 40kph and 60kph with about 1,500rpm, the car shakes, has a type of vibration. We can only replicate the issue about 70% of the time.

Any idea what it may be? One of the Engine mounts were changed before purchase so maybe the mechanic didn't put it back together? Gearbox? I don't think it's wheel balancing as the issue is not 100% dependent on the speed.

Could this be the issue?

100% problem lies within the driveshafts. Its a common problem on nearly all euros. My mate has a euro 04 lux and I was told that you just need to change out a washer or something.

Anyone know what washers need changing?

Thanks for the reply mate. After reading through a couple of threads it most likely is the drive shafts.
