I have used KYB products several times, but NEVER again.  Simply put, KYB
products are junk.  What good is their lifetime warranty when their parts
only last a third as long as the OE item which was replaced?

In my firsthand experience, the most condemning examples of KYB's shoddiness
were the KYB upper strut bearing mounts which I installed on a Volvo.  In
less than 3000 miles, the bonded rubber was visibly separating from the inner
and outer metal components causing the mounts to be poised on the verge of a
catastrophic failure.  It doesn't take much foresight to know what happens
when the upper mount on a MacPherson strut comes apart.  Of course, my parts
guy told me that they would be covered under KYB's generous warranty, but, as
I asked him,"Are you nuts?!"  I got my money back.
