I've been having a knocking sound coming from my front suspension, and it is noticeable at different speeds too.
I had Pedders check all suspension on the car said they said that it was in great condition, the only thing they couldn't check was the shockie mounts.......I think that's what Dasic1 is referring to??
Toyota have also told me that it is common for them to fail......and after 19 years its probably time to replace them.....nothing lasts forever.
