Steering feels like driving on a ridged surface

[Juan]

Hi Everyone,
Imagine you drive thru a work area, the crew is re-surfacing the asphalt, You enter sections where the giant machine has peeled off about 2-3 inches of old asphalt and left exposed a ridged, raw pavement, that while you drive on it, you feel almost like a buzzing vibration/feel on your steering wheel, you hear only a slight buzzing that coincides with the buzzing feeling on the steering wheel. Only thing is, this only happens when accelerating. If you start coasting on the highway taking off your foot off the accelerator the buzzing feeling also stops (ruling out ball joints and most suspension parts?).

This is a 2006 Odyssey Touring. I recently replaced the timing belt and w/p, spark plugs, flushed coolant completely and i n the process replaced the passenger-side motor mount with an aftermarket unit. Could this be related to the motor mount causing engine vibrations? Other than heat shield vibrating noises from the car’s ‘s in great shape, perfect condition.

Any suggestions would be greatly appreciated, so thank you all in advance.

Did the problem exist before any of the work was done?

Thanks for your reply. No it didn’t. I changed the mount since after removing it for the timing belt job I noticed the previous one was cracked, but I’d not felt any vibration or anything prior to doing the job. The work was done around June, so it’s been a few months. The timing belt had been replaced at 106,000, but the water pump seal flattened at around 148,000 (June) and it started leaking coolant into the timing belt so I did the entire job again replacing the water pump and the mount included. I used OEM parts for the timing belt and components except for the mount. This started the past couple of weeks or so. I’m suspicious of the motor mount, since it was an aftermarket. Afterwards I started remembering how in the past I’ve had to go back to OEM mounts as aftermarkets have not fared well for me. But, could it be something totally different?

From time to time the power steering doesn’t seem to work great at low speeds and steering becomes hard, no noise nor whining from the p/s pump, just intermittent hard steering at low speeds (a new drive belt was also installed at timing belt job). Also of note, we have been experiencing vibrations when braking at high speeds so I bought a new set of slotted and drilled rotors and quality brake pads which I have not installed yet. The vibration is only felt when braking from a high speed.
Thanks a mill

To try and find this, You may need to put it on jack stands and have a helper
put it in gear to see if the noise/vibration comes out to pin point it. You could
also try and put the van in gear with foot on the brake to see if the motor moves
to check mounts.

Recheck fasteners on the motor mount ?

The brake noise may or may not be related to the vibration Recheck the fasteners for the brake components .

God bless

Thanks, good idea, I’ll try it and report back.

Thanks, I did and it seems to be well fastened. I’m going to try college man’s suggestion as well as removing the mount itself and physically inspect it. I’ll report back.
Thank you
