After I took the spare off and put the original wheels on the vibration is a lot better! One thing I noticed when I was doing the Bushing install was that the rotor are held on by wheel and the lugnuts. I couldn't believe this, seems pretty generic. I'm starting to think my vibration might have something to do with how much torque I use on the lugnuts!! BTW I used a torque wrench at 85 ft/lbs.

And for the clunking noise I have, the only time I get it is when I'm braking around a turn. If I brake going straight no noise, if I go around a turn with no braking no noise!!

Down here, labor is usually $300-400 for everything.

Just find a shop that can press out the bushings for you and then reinstall the arms yourself.

My question is what do i change next i have the poly steering rack and the sways. i replace the ucas and the balljoints and the outter tie rod ends and the shocks i didnt replace the bump stop in the shocks and the rubber insultor (if it makes a diffrance at all). Should my next step b the replacement of the lower arm?

b/c things changed majorly in those years. I didn't research much about ball joints so I can't say anything for sure.

As for the tension rod, I was afraid that since I got information from researching sites from Japan and calling up Netz and TRD in Japan that it might not fit, but 03-05 arm is a direct bolt on to a 98-00 chassis, my GS is a proven fact that it'll even work on USDM GSs.

Beefier arm and bigger bushings from what I can see. From what I researched, these bushings are stiffer than 98-00 OEM and have TRD equivalent bushings. The TRD site even says that 03-05 has TRD equivalent bushing or something like that. Parts number match from the Japanese sites I looked at. HOWEVER, listen up Lexus, you're a ****ing rip off. Lower arm no2 are sold in Japan for 50bucks per side. In the States? 200 per side. What a bunch of horse****, seriously.


No idea about the material and durability. It's hard to compare since most people wear the **** out of these bushings and then change them to a newer arm in Japan.... but, from that torn bushings, I think it gets A LOT of stress, especially if slammed. Converting it to a heim joint may not be a bad idea if you want to super slammed and drive a lot.


yes. lower arm no2 in toyota speak. I think usually referred to as a tension rod.

Hope that helps. I'm here help out but don't expect me to be a black box that'll spit out information that you want (meaning don't send me a PM asking me some stupid *****).
