Worn Lower Control Arm Bushings = Floorboard THUMP when braking ?
SO over the past month our GS430 has been making a THUMP noise on the floorboard while braking just before the car comes to a complete stop. I took it to a local (non-Lexus) shop and they couldn't tell me what it was .... they thought it might be my aftermarket rear rotors but that's BS because those rotors have been on for a while.
Lower ball joints were replaced last summer along with the tie rod ends.
I got the car on a lift tonight and saw this AAAAAAACK !
I'm guessing I need to call my freindly neighborhood Daizen dealer ?

Yes you'll need an alignment. Your caster spec has changed since the bushing are worn out. The toe changes as soon as caster changes, which is why some people are experiencing vibration and/or irregular tire wear.
If you need to do any other suspension work, now is the time to do it.

There are no OEM bushings available. Daizen's kit includes bushings to service all the front bushings: Caster, Lower control, and Upper control. Go look up the picture and you'll see whats in the kit.
TRD also offers bushings (rubber), but they're a 3 month wait from Japan and it's not definite that they'll fit the USDM GS.

I need to replace these this weekend as well... Anyone have a DIY link handy?? I will do a search.
I have seen the DIY for the steering rack bushings but not the control arm bushings.
What does the kit include?
