I have a '92 which started a random clicking in what seems to be the drivers side of the engine block, towards the front. It doesn't "click" at regular intervals nor increase w/ rpms. It seems to be completely independant and doesn't affect performance...yet. I'm nervous it's a precursor to a serious issue! Thanks in advance for any help

 

I have similar issue and don tknow what it is. I think it might be front drive shaft u joints or Axel u joint

 

It's definitely not in the suspension/steering. It will happen even sitting at idle. It almost sounds like an overheated radiator would after you cut the engine. Thx tho!
