Hello, 2001 Civic 5-speed between 50 and 60 there is a noticeable vibration in the right front. Had tires rotated and balanced and moved tires around and no help. Visually looked at the CV shaft, rotors, and no issues were noted. The ball joints look good, the steering wheel vibrates a little at this speed. The shifter does not vibrate and can't feel anything through it, and when I brake at this speed no issue with the pedal or braking action.- TIA

 

Best guess its a component that’s moving is causing the issue, I’d retorque the axle nut if you haven’t already and move tires with the least amount of weight to the front and the one with me most to the back right.
Assure your alignment isn’t off badly. Not sure if there a motor mount in the passenger side but if it were worn out it might add stress on that side of the suspension lmk if you happen to find it

 

Having the exact same problem, have changed outer tie rods, recently had front right tire off and on a whim i grabbed the sway bar and snatched on it, there is play there, i changed the away bar links out two years ago, ill probably be doing it again.

 

Fix found the driver's side cv shaft was the issue after doing the passenger side lower ball joint and cv shaft. Got the driver's side off and pulled out the shaft it was split (Boot) but you could not see it as when it was installed the pressure from the spindle assembly was keeping it in place. I know some may say look harder but when I jacked it up and looked with a light did not see it, and I did not put my hands on the boot itself, so lesson learned Hope this helps someone else, on to the next issue.

 

I've been experiencing a sort of elliptical sound once i start accelerating that sounds relative to the wheels possibly, there is occasional clicking when slowly pulling into a parking spot so I'm 80% convinced it stems from a cv axle issue?
