What is your question?
I'm familiar with the famous G35 defective compression rod bushing issue and had the bushing replaced (4 times and counting on same side) but the knocking/clunking noise continued to occur over bumps, gravel, compacted snow, etc. At the mechanics advice, the sway bar links, strut mount and upper control arm were replaced and the brake calipers were greased and checked...knocking still occurs. NOW being said that it's the lower control arm on front right side making the noise but I'm not entirely convinced. This issue has to be resolved NOW and I am NOT happy that any of the so-called "professionals" cannot source the knocking/clunking noise. QUESTION: could the knocking noise be caused a worn strut or strut assembly (despite no leaking or other obvious signs of being worn out) or a loose wheel bearing assembly?

Yes! .
Not likely. I still have the knocking noise. Dealer said to replace the control arms, CV Boot. Took to independent mechanic and he said control arms were fine, but to replace the struts, CV Boot and Axle which I did. Still knocks. Had planned to replace this bushing. Guess I'll assume that won't work. Independent mechanic said to replace sway bar. Sounds like endless problem. 125,000 miles
Both mechanics claimed they knew the reason - replacing struts and CV Boot/axle did tighten it up and drive better but the reason I took it there was the knock!!!
Google > Chassis Ear... Find a shop that has one.
Thank you for the confirmation reply but is there any way of knowing for sure what the source of the knocking noise is? I'd rather avoid the process of elimination routine (and expense!) and with those two things to add to a growing list, I'm becoming concerned that this will be end up being an excessively expensive fix...any and all help and/or guidance would be greatly appreciated.
Suspension noise is a difficult problem for any mechanic to diagnose.... there is a tool called **'Chassis Ear'** that can be very helpful in this process. However not all repair shops have this... try to find a shop that does and have them hook it up then test drive your vehicle! Parts replacement based on a guess is 'always' much more expensive than testing!.. Good luck with it!!
