94 honda civic d series conversion to b series everything been replaced e.g lcas cvs hubs shift linkages. Knockong still coming from under floor pan passgener side front sounds like flat spot in wheel but wheels are fine thought maybe wheel barring but swapped that over still doing it nothing is loose and everything that is obvious has been replaced only knocking from passenger side front any ideas not sure where to go from here tried every obvious option still doing it when you drive the car at 15/20 kms an hour havent gotten over that speed any ideas on where to look mext?

 

axle binding? I had a similar problem with a swapped car when I hit 45-50mph
