horrible noise seems to be behind driver side tire

What is your question?

bought this car used. we suspected it had a little damage to the axle because there was uneven wear on the rear brake drums. replaced rear brakes. squeaking stopped, now started again less than 6 mos. later. Now I went to drive yesterday and i heard a crunching squeal noise ! sounds like a soda can being crushed by steel cog-wheels. i read a q&a talking about worn outer tie rods, is this the problem or something else?
