Hey guys,
I have had the same issue as well; sounds of knocking/loose in the front.
The thing is i have already installed a sure rear engine mount (found out the factory one had already cracked, nice to see how mazda notes they checked all engine mounting brackets as stated in the service i did)
Also there was no knocking since then, knocking started happening about a year later and also when the knocking noise got worse sounds like the whole front suspension was very loose on bumpy roads.
found out that the rear bushes on my left control arm were cracked, so go them replaced with whiteline control arm bushes for both sides. it improved a tiny bit, but the noise is still there **SIGH**
Next im getting my mate to look at my shocks (which mazda told me they are fine, as well as signs of no wear and tear) although they failed to mention me about the cracked rear control arm bushes.
Any others had any problems like this and found the reason for the noise?
