Ok, I'm having two problems.

1) Occasional popping from the front end, not a very sharp pop but more of a clunk. Usually happens while turning and hitting a bump. Inspected tie rods, ball joints, all look fine. Nothing on the sway bar looked bad (that I could tell, maybe i'll post pictures) Did notice this with the control arm busing but I asked a few people on here a while ago and they said most likely not causing the sound.

2) Second problem that i just noticed is a faint gear/groan noise from the front left wheel while turning sharply at low speeds like pulling into a parking spot. It almost sounds like a tire rubbing on a piece of plastic which i checked for and thats not the case. First thing that came to mind is the axle (new wheel hub installed like 6 months ago). It only makes noise when turning as hard as you can to the left (forward and reverse) and noise is definitely coming from the drivers side. I took a look and found this.

Clearly the boot is torn to some degree and I'm losing grease. Not sure if that is a lot or not but its definitely leaking.

Do these two problems seem related? Like, could the pop/clunk noise be coming from a potentially bad drivers side axle if that is whats bad?

Lower motor mount was just replaced, I thought that was the problem because it was starting to go but still makes the noise (although it seems to make it less often now which seems odd).

Thoughts?
