I started noticing a vibration on the front end about 3 months ago. The problem becomes noticeable when you reach a speed of about 57 mph. It gets worse up to about 70 mph. If there is no acceleration there is no vibration. When you start to increase your speed the vibration becomes very noticeable; especially when going up a slight incline. So far I have had the front tires balanced; both axles replaced; and two motor mounts replaced. Still the same problem. This cost approx. $1,000 and did not help any. Note that both front axles had busted seals and one motor mount was broken. So, the $1,000 spent was not a total loss. Very strange situation.

Update from Mar 18, 2016: A local tire shop replaced the motor/transmission mount. This fixed my vibration problem. They also changed both front axles as the rubber boots were busted and losing grease.

My wife and I bought a new Odyssey EXL/RN in Tampa back in 2006. Starting at about 272 miles the steering wheel started shaking/vibrating. I also noticed that when the van was under load at acceleration and on load in corners, that a weird humming type vibration would occur. The van now has 37,000 miles We have been through two sets of Michelin LX4 tires which have been road forced balanced about ten times, two new front axles, four new alloy wheels, two new front rotors, and one new rear engine mount all in effort on the dealers behalf to cure the vibration problem. I have heard bad things about the LX4 tires which may or may not be the problem in the steering wheel vibration. The other vibration is beyond me, the dealer just scratches their heads and says hummm!!! I would never had thought I would have such a nightmare ordeal from buying a Honda. This problem has consumed a large part of our lives since day one. What do We do?????
