front axles

So, I have a 2001 325xi. When I bought it, the front boots were torn, and the left made a little noise so I knew i was in for axle replacements and got the car for the right price... I replaced both sides and being a cheap daily driver I went for the chineesium option #1 (Cardone). After driving, I got a vibration in the front end 75 mph+ that seemed on longer drives to get a little better. It would go away if turning at speed on the freeway and then come back when driving straight. Frustrated, I tried Chineesium #2 for a little more money (TruTrak) and now its much less of a vibration but still there.

Am I crazy if I keep assuming the issue are the axles and buy GKN ones this go around?

Is it important to replace the right Front Axle Support Bracket as well? I can't find anything on the forums where this is a failure component.

I cant' find any play in the front driveshaft at the TC or Diff, but now I'm questioning if I have a diff issue? Also doesn't seem to be a common failure point from my searches.

Let me know what your questions and thoughts are.

If you haven't already, look at your engine mounts and transfer case mount as either can transfer vibrations if they are in rough condition. When I replaced the front axles with GKN and replaced the engine mounts, the majority of my vibration was eliminated but it was ultimately replacing the rear driveshaft, at around 192k miles, that eliminated it completely.
