Vibrations 40-50mph,

[Geordieguy]

Hello, I've joined this group in the hope that someone can help me diagnose and fix a problem with my 2010 honda Type S when accelerating between 40-50mph my car vibrates from the front passenger side.

Wheel alignment checked, Wheels checked and swapped, tyres changed too, yet the issue persists.

Has anyone suffered from similar and if so how did you fix it?

I'm starting to think it could be driveshaft related.

Thanks for taking your time to read this, I'd as appreciate any feedback.

I don't think it is drive shaft issue and never change original shaft with much inferior after market. 40-50 mph vibration is usually caused by tires imbalanced. 

Take a look again your tire balance. I had the similar situation before, it turns out the Walmart tire service install 2 balance weight on 180 degrees on inner side. It should be one inner one outer to eliminate lateral vibration. 

Driveshaft in Honda never have any issue unless you went to a ditch.

Another part that you can check is the ball joints (upper and lower) because Accord have double wishbond suspension.
