Clunking noise when braking
My 91 LS400 (160K) makes a small clunking noise under moderate braking, especially when turning left at the same time. The noise seems to come from the front suspension on the passenger side.
Anyone experienced similar thing and has a clue how serious the problem is?
Thanks,

could be your swaybar bushings, or control arm bushings... theres a bushing in the suspension somewhere that is producing that sound. I would start with your sway bar bushings.

Cunking noise in front end
My guess is that you need to replace the strut bar cushions.
I chased after the clunking on my 1990 LS400 front end, and these were the culprit.

Yes, that reminds me... the clunking sound came from my front left... the technician told me there were "plastic sleeves" between the spring and the strut hat on all the others but the clunky one.
Its gone now, but where do i get these strub bar cusions, or sleeves, or whatever they are? Whats the part description? They called a lexus dealer and they werent able to find a part.

Front end Strut Bar Cushions
Your Lexus dealer couldn't find these? I ordered mine from Carson Toyota in LA (888) 747-4777. Gordon knows exactly what they are. This is the terminology out of the factory service manual. I'm just a little surprised that your dealer did not know what these were nor could he find them listed. you will need one for each strut bar (total of two).

I did have new sway bar bushings installed, these cost like $5 each, and were very small... we're not talking about these right?
I think their a plastic boot that goes over the struts "hat" and would keep the spring from making a clunking noise (i guess)
Its not the spring insulator... I had all 4 of them installed when i changed the struts a while back, those are also known as "shock boots"

I had a test drive with a Lexus mechanics and he also heard the noise, but after spending more than 15 minutes checking the car he couldn't find anything wrong with the suspension. It's probably not serious but it's annoying.
