Welcome I'm Chris aka Moose
On the noise, I too agree the CV joints should be ruled out being they were swapped, so lets also rule out a wheel bearing going bad, by loading up each side with some safe but harsh swerving. If you can ever get a hum or moan as well as the click then do suspect a wheel bearing. If you can not get those noises then try the vehicle on a rack or stands so you can see if the noise can be identified from under the vehicle while driving and turning. The next thing to pay attention to is the differential where both axle shafts go into the trans.
For the converter, I recommend a fluid service with an additive called lubegard prior to swapping out the converter for those issues you noticed.
