I have a set and I think over the last couple months one has developed a clunk on right hand turns--have to turn sharply, and it doesn't do it all the time, but it makes me think I have a bad strut bearing. 2 years and 60,000 miles plus. Maybe I can't complain--I think there might be a lifetime warranty on them from Pep Boy's, in which case I could swap and be out the price of an alignment. If I could do that, then it's really not that bad of a situation -- it's my beater Camry so changing spring rates isn't high on my list of cares.
