Well, mine is back again after ~3k miles. I got the front discs lathed while on the car. I did this thinking it would compensate for any issue with the hub running out of true. The issue was on the NSF, disc was badly warped prior to lathing. For a while after lathing it was pure bliss but eventually....
Same as others, I feel the judder above 60mph, only when the car has traveled for 30 mins or more and the discs are warmed up. I am really happy that the calipers or sliders are not over heating as they are fine when i pull in and check them for any sign of heat. I have rebuilt the entire braking setup on both sides at the front if folks here recall.
Do others on here feel the vibration in the pedal or the steering wheel or both? Wear socks only to be sure its coming through the pedal.
I also had a lower ball joint replaced on the NSF and wonder if its somehow linked....
The comment from Lexus about the issue being at the back is interesting! I'm beginning to think there may be something in that..Damo2 I would go back!
My stub axle bushings have play and need replacing but the non genuine options on ebay and elsewhere are rubbish by all accounts. We know what Lexus suggest and its big money. But could issues at the back be somehow linked to the front?
Has anyone on here changed their back discs or pads during their struggle?!
I'm gonna drive in my socks for a bit and report back exactly what amount of judder is coming through the pedal and wheel.
My car is perfect apart from this, which is why its driving me crazy!
Surely someone out there has the definitive answer! Chris appears to be the only one to rectify but his fix has not worked for others.
Chris - Are you still judder free?!
Are there other IS forums that might be helpful, plenty of guys driving their IS200s much harder than any of us i bet. They might hold the answers!
Have lexus a website that you can submit technical problems like this?
