I have an 8th Gen 2009 Honda Civic LX-S 5spd sedan that I purchased new with 108k miles. It now has a wobble feeling when accelerating at around 45-50 MPH.
A year or so ago I started to notice a roar sound that started to get a little louder as time went on. A few months ago I got under the car and found that the roar was coming from the driver's side front middle, not a wheel bearing, or outer joint. So I took a chance and replaced the driver's side axle thinking it possibly may have been the inner joint. That didn't fix it so I ended up having to get the 5spd transmission rebuilt because it was the main shaft bearing that was roaring. I didn't feel a wobble after the rebuild, but I do now and it's been about 3 months since the rebuild.
I really don't believe the wobble has anything to do with the rebuild, do you? Could it possibly be the new drive axle, or could it be the passenger side axle?
I always keep my tires and wheels rotated and balanced, and had them done today and I'm still feeling the wobble.
How do I find the culprit of the wobble?

Well the wobble could be tons of things. I would say go to a good front end shop and see what they say. But of course it could be internal to the transmission if somebody rebuilt it very rarely. Does anybody know how to rebuild those things correctly anymore? They're so complex inside. That could easily be another bearing inside the transmission
All 6 bearings were replaced during the rebuild. Remember, it is a manual and I would think if it's a bearing, I'd hear a groan, no noise at all.
