HELP! Chasing Front End Clunk, LOST!!
#17
There is no radial play, they sit very nicely on the hub. There is however a lot of tangential play (probably close to +/- 1/16"). So I can see that if the lugnuts are not tight enough, the rotors could potentially slide around back and forth. Though I think the lugnuts would need to be dangerously loose for that to happen.

Go to https://secure.drivers.lexus.com/lex...-lexus/home.do and register your car to see the service history. See if you can find history of the motor mount being replaced.

I got the "gold" level front rotors from advance auto. Passenger side fits much better but still has gap between the stud and the hole. the drivers side really wont even hold itself up on the hub. It has a hole on the rotor where you could screw it down to the hub, but my 99 doesnt have that hole. That would solve this problem but it seems it wasnt used until like 2000+

strut
strut mount
outer tie rod
lower ball joint
sway bar link
lower suspension arm no 2

brake pads
I literally just got the car back on the road on monday and started noticing it yesterday.

Are you sure you go the right rotors for the car? The hub and the rotor should have a pretty close tolerance, as that is what maintains concentricity, not the studs.
That threaded hole in the rotor is not for bolting the rotor to the stud, it's for threading a screw into it to break away a frozen/rusted rotor from a hub.

Did you load your suspension before torquing all your bolts? I changed all that stuff last year and didn't put enough of a load on my suspension when I tightened it and it would make a popping sound. A week later I loosened everything, then retorqued everything with the proper load on the suspension and it was all good.
Update...this might be too early to say...knock on wood... but this morning when I drove to work no more clunking sound. Still curious to know what it is.

I think im going to go ahead and go after a new rotor for the drivers side. I just cant help but think that is the source of the problem. Every time the front end compresses a little or with any potential shift of the front wheels, it clunks. I go from park to reverse, the wheels move slightly, clunk. Back into drive, slight movement, clunk. Any time the wheel changes direction it makes a sound.
