Ok so I have replaces both upper and lower ball joints, swat bar end links and bushings, and the outer tie rods. The brake pads don't look like they are moving either. The clunk always comes when I am going slow. I am at a loss. Does anyone have any ideas? And also my headlights don't go out every time after I turn off the car and the switch is on auto.

 

do you have the noise and a thump? if so, I would check the Tranny mounts.

Yes there is a thump. Will be checking the trans mounts tomorrow

 

Like a surge, then yes, check the tranny mounts.

 

And how would I go about checking them?

 

I have a similar problem but it only when i break. I dont hear a thump noise though. I already replaced lbj.

 

The only way I know of to check the tranny mount is to take it out, then you might as well replace it. Transmission mounts are cheap like I said before and it takes about 30 minutes even if you have never touched a wrench before, it will be more like an hour if you got rusty bolts and such. Even if the issue was not the tranny mounts, the tranny mount really does improve the ride!

 

Yeah I was thinking the same thing. Any brand I should steer toward or away from when it comes to the mount?

This is the place i got mine from, I think...this will fit your 98 Lexus GS. Just out of interest, is yours a GS3 or a GS4?

 

mine is a gs4

 

Well go ahead and give a search on the internet and find the ones you like best, or which ones are the cheapest.
Probably will be about $60.
