So I lifted the 4Runner about 2 weeks ago. Pretty much ever since then i've had a horrible squeak. Determined its definitely rear end area. Sounds like its coming from my passenger side coil (toytec superflex) on the top.. Its seated correctly and everything is tight and doesnt move. It just SQUEAKS and it makes me insane the kind of squeak that is horribly embarrassing going though parking lots but I can't figure it out for the life of me. Any one have any input?
