1990 LS400 Diagnosis of Front End Vibration
When I brake I get vibration of the front wheels and sometimes I hear a clunk sound. I replaced the lower ball joints and that helped but still have the vibration. Could this be the bushings on the power steering rack? How can I diagnosis this problem? I keep thinking it is either the front brake rotors or the power steering rack.
Your help will be greatly appreciated.

Currently looking at a similar issue on my '94.
Question I have is, has anyone ordered poly strut rod bushings from PRI Racing?
LINK TO PRODUCT.
What I was wondering is, what kind of effect will poly bushings have on my ride if I use them just for these bushings? I don't want to create a harsh ride but these are priced very nicely.
I don't see the OEMs listed anywhere online and I'm not sure if someone like Carson would deliver to Canada. Not sure what my options are apart from paying the canadian stealer a whoping $240CA (about $200US) EACH.
