Okay guys, when I made my first post I was doing it rather quickly so now I'll make some clarifications.
When I mentioned the "right" side I was referring to the passenger side. The clunk noise was there before I replaced the OEM struts to the new KYB-GR2s. I bought everything that was needed to replace them the correct way. Strut, boots and new mounts. I reused the original springs as there was no need to replace them. Nothing seemed out of place on them.
After I replaced the struts the clunk wasn't apparent as with the OEM struts but that was due to the fact of the stiffer suspension. The clunk was still there if I hit a bump hard enough.
As per the instructions on what to check on the "02-06 Altima Clunking From Front End
" thread I'm pretty sure I ruled out the list. I'm not a mechanic so I don't know exactly what to look for. And duplicating the noise can only be done while the vehicle is in motion.
I have jacked up the right wheel and shook it from side to side and from top to bottom and feel no play in it. I performed the motor mount test and the engine doesn't seem to have any abnormal play in it nor is there any noise while the test was performed. Its possible I have a defective strut but unlikely.
As I mentioned in my earlier post I feel a grown/tapping while braking from 5-10 mph. Recently I noticed a faint clicking/tapping noise while going over speed bumps at an adjacent angle. But that could be anything with the entire car moving around. I still have not done the rear shocks due to lack of cash atm.
I will continue looking in the areas that peelman suggested. When I was tightening the strut brace none of the bolts seemed abnormally loose but I did tighten them a bit.
I thought by replacing the front struts would solve my clunking problem but apparently there are more components to investigate. I hope it won't be a major repair such as the lower control arm. I would like to know just what it is. These noises can be such a mystery.
Thanks for your help guys. If you have any other questions or suggestions please feel free to share them.
