Random weird wheel vibration on 2001 Acura MDX

Occasionally experience weird wheel vibration/shudder when driving. Typically happens at near constant speed between ~ 20 - 40 mph on a level paved road. When I back off the accelerator slightly the problem goes away. Will generally happen about 2 - 3 times within a ten mile drive. Vibration seems to be coming from front passenger tire, but hard to tell. All tires in very good condition. Car mileage ~ 130K miles.

Conditions stated would lead to costant vibration, not intermittent. Problem is intermittent.

Just got the same issue with my 05 mdx,I went to balance the tires on a place that only does tires, they balance them 3 times(only pay for the first one), and still vibrating, I call the dealer and they told is balancing, so I did not want to keep on trying at the same place, so I look on the web for similar issues and find out that I need it to take it to balance to a place that uses a machine call the road hunter GSP700, luckly me my regular mechanic has one of them, so I took it there, and after $70 dollars, problem solved. He mentioned that some luxury cars need a more precise balancing. I have not got a issue with wheel vibration since then, all this happen after I put new tires at the place that try to balance the tires. they did a good job with the tires, but the equipment that they have, is not as new as the road hunter.

It's possible you are experiencing a shuddering due to the torque converter going in and out of lock up. It usually happens between 35 and 40 mph under light throttle and will also make a noise. The fix is a new torque converter.
