Not sure of the answer, but some things to test to MAYBE help find the issue...
I would be doing every "test" I can think of and write down the results. As an example.
1 when it wobbles, downshift and maintain same speed....does change anything?
2. Does the wobble frequency change with speed changes?
3. What happens if you shift into neutral and coast?
4. Have jacked up the front and spun the wheel by hand and listened. Touch an automotive stethoscope to hubs and see if both sides sound the same?
5. Check runout on wheels with dial indicator while up on stand.
6. Are all balljoints tight and not worn out.
7. Could be the hubs/bearings, even though you can't feel by tugging on wheel.

1 when it wobbles, downshift and maintain same speed....does change anything?
-No. I have done every imaginable scenario from slow / fast acceleration / braking / downshift. Nothing changes. What's even stranger is the wobble / noise will be present while driving then I come to a stop at a light then begin acceleration and the wobble / sound goes away then will randomly start back up for no apparent reason or change in driving style.
2. Does the wobble frequency change with speed changes?
- No. As mentioned in previous question I have run every possible scenario and cannot find anything I can peg the occurrence to.
3. What happens if you shift into neutral and coast?
- Same issues.
4. Have jacked up the front and spun the wheel by hand and listened. Touch an automotive stethoscope to hubs and see if both sides sound the same?
- Did this a few weeks back before I replaced pads, rotors, and CV axles. I did not use an automotive stethoscope on the hubs but I did rotate them to see if I could feel or hear any noise at all and I could not hear a thing. The wheel was very tight on the hub as well.
5. Check runout on wheels with dial indicator while up on stand.
- We did this when I changed out new wheels and tires a couple weeks back.
6. Are all balljoints tight and not worn out.
- Yes, tight and definitely no where close to being worn out. Admittedly, I wheel, however, the area I wheel is not rocky terrain and is more steep hill climbs, deep sand, and mostly moderate to difficult trail features but no rocks.
7. Could be the hubs/bearings, even though you can't feel by tugging on wheel.
- As crazy as it sounds this is what my intuition has told me from the beginning. I was on the fence about replacing the CV axles and waffled between those and replacing the wheel hubs. The only reason I didn't go wheel hubs first was how tight everything was and I couldn't hear anything that sounded concerning.
I guess I am going to pull the trigger and order the wheel hubs tomorrow and find the time next week to do this.
I appreciate all the help you've offered. It's been a big help believe it or not.
One last question. This is the first time I've dealt with wheel hubs. In the past I've only worked with wheel bearings. I've replaced wheel bearings in the past based off of the usual and customary tell tale signs. Is there something different with a wheel hub that makes it more difficult to diagnose than traditional wheel bearings?
