I have a 2006, EX Honda Odyssey with a side to side steering wheel vibration from 60 mph to 70 mp. The vibration comes and goes and when it vibrates it gets into a harmonics that requires slowing down to 45 mph to go away, shifting to neutral makes no difference, sometimes turning the steering wheel calms it down if there is no feathering on the tires. When the tires were rotated it use to gets better but the problem has gotten worse. I've replaced all except engine rear mount & steering rack. What is that I should try?

Oscillations in steering wheel when accelerating through 60 -70 MPH. Honda service center said that this was due to either hole in high pressure hose (power steering high pressure hose leaking & sucking air) or bad steering rack. Quoted cost was to replace high pressure hose.

Update from Sep 7, 2016: Replaced the high pressure coupling and power steering hose and had tires balanced and rotated. This seemed to wholly alleviate the problem. Even when accelerating through 60-70 MPH and upward I feel no vibration.

Took the van in because my wife couldn't park it the steering was so stiff. They replaced the power steering pump and it cured the stiffness in the steering. then we noticed small jerking type feedback in the steering wheel at almost all speeds but most noticeable at very low speeds. Took van back and was told I have a problem with the tires. I think the steering rack is hooped and that's what caused the PS pump to crash in the first place. I will change the tires out and I'm hoping they're correct about that being the cause. I hate to think what kind of fight I'll have if the steering rack really is done. If they say it's a "typical feel' or something like that, I'll come unglued. I'll update as soon as tires are changed. The initial inspection cost me $90 bucks to come up with the "Tires are bad" answer. Good luck Honda if it isn't the tires!!

steering wheel vibration from the day we bought the vehicle. we now have 32000 miles less 5% (that's another issue) and have had 3 new sets of tires along with rotating, balancing, new set of wheels/rims... from another van, and axles replaced and we still have an annoying as hell vibration in the steering wheel. seems to be most noticeable at 70+ highway speeds. One set of tires was even "road force balanced" (that was a $75 hit out of my pocket) and the issue was tire tread wobble? i think Michelin is in on this conspiracy.

I have experienced the same thing as Bob - excessive vibration at 3 points - when the car was taking off - when the car reached around 60 mph, and when the car started to brake. Had it in 3 different times for the same thing - they said I needed new tires - got new tires - they said I needed an alignment - got the alignment - then they said they didn't know what it was but that they would take a look at it. Today they called and said they THINK it's one of the engine mounts. Supposedly the engine mounts have little motors in them to absorb the vibrations from the engine. They have to order the part of course - so I'll let you know next week if that helped.

While driving at steady speed (40-50 MPH) I feel excessive road feel coming through steering wheel. Even on very smooth surface I still feel it. It is not the vibration from being on over drive (5th gear) at slow speed. It almost feels like I have off road tires on vehicle. Dealer and Factory Service Rep. say this is a "Driving Characteristic" for this vehicle. They are talking about the vibration felt from being in overdrive at a fairly slow speed. I can't get them to ignore that and concentrate on the other vibration.
