[just wondering]

I recently had the timing belt, balance shaft belt and oil seals replaced on my '98 Odyssey. Now the van has a persistent new vibration at all speeds. It seems to run fine, but we don't like that new hum. We checked and replaced the front motor mount which was worn out, but that made no difference. I've read that you can get major vibration from the balance shaft belt sprockets not being properly aligned, but no one mentioned if it could be a little off and create a noticable but not bone shaking vibration. My mechanic, not having driven the van before, doesn't notice the vibration as something new, and it's a fair amount of work to go in and check, but I don't know what else it could be. Any thoughts?

If the balancer belt is mis-timed then you do get a vibration how bad the vibration depends on how far out the shaft is. I've driven a prelude with the shaft 180 degrees out and the floor shook very badly, however I also drove a accord with it a couple of teeth out and the vibration was hardly noticeable. I would ask the garage to check it out it's only a hour job to remove the covers and check the timing. One thing to mention if the vibration is left then this can have an effect on the bearings and the oil pump so don't leave it too long.
