My passenger axle started leaking... here is what happened.

I replaced the passenger side and thought, why don't I just change both out. I just bought some new axles from Oriely Auto Parts... I put them in and took them for a spin. Immediately I heard clicking noises coming from the axles.. they make noise when I accelerate in a straight line, the clicking noises click faster as I accelerate faster.
I made sure all the bolts were tight (axle nut torqued to 170ftlbs and axle shaft output bolts to 20ftlbs)
I am not sure why the clicking noise is still happening.. I read that you should grease up the axle... which I didn't do, maybe thats why its clicking?
I also heard that some axles don't work with low cars... the cv joints will click.
Can anyone help me out?
My car isn't really that low... (ignore the stupid camber, i just installed my rucas in this picture
