Just talked to the Wheels at Lex and they are unaware of any new suspention, hitches, or roll over airbags I just cannot figure this company out, Why not let the public that buys these things now what they are building?? Has anyone seen the new suspention?

 

It's supposed to be on the 04' something called Kinetic suspension, however I have my doubts that it will be out in late August. I think more around October/November will be more of the time frame and I have only heard rumors of the new suspension type for 04' nothing confirmed.

 

I was experiencing vibation, but after turning down the music the vibration stopped. If this is not what you are talking about, I guess I'm one of the lucky ones that doesn't have the vibration which you are mentioning. Of course I still feel it because of my music.

 

I raise the tire pressure from 32 to 37 psi and the 55-70 mph vibration is gone. The very light 1700 rpm vibration is still there but it doesn’t really bother me that much.

I will lower the tire pressure back to 32 psi this weekend and see if the vibration comes back.

BTW, is there a safety concern on 5 psi higher than Lexus recommended tire pressure?

 

super...what kind of tires are you running?

 

Bridgestone

 

damn..i was hoping you would say dunflops

 

I have Dunflops and I raised the pressure to 35 psi, the vibration was corrected. I asked the dealer service people and they claim to always set the pressure to 35 psi.

 

This poll is flawed in the sense some of us are on the second GX and it will only let you vote on one vehicle.

 

I'm seriously considering buying a new '04 with the new GVWR. I keep reading about the vibration issue, but I have never seen the phenomenon explained. When I test drove an 04 this weekend, I felt a slight fine vibration in the steering wheel, but I thought it may be due to me not being used to a wood wheel. Is this what you guys are talking about?

 

I've had my '04 for about a week now and have not experienced any vibration! All of these threads are a big reason why I waited and didn't get an '03. I've made a point to pay very close attention to the truck while driving, and after almost 500 miles, I got no vibration. Maybe I'm lucky?

 

I think people's definition of a vibration might be different.

I think the word vibration might not be the best word to decribe it. A slight hum (not in the hearing sense, but in the feeling sense) in the steering wheel might be a better description.

Maybe this analogy... Picture driving a car, any car, over slightly rough pavement, you know the feeling of the road you get in the steering wheel, well this issue feels similar to that except on the GX that feeling happens anytime you are lightly on the accelerator and in the RPM range of 1200 to about 2000 RPMs in any gear and as soon as you release your foot from the gas the feeling goes away.

We are not talking about your hands are shaking and feeling numb kind of vibration.

Of course your situation may vary, but I have had two GX's now and they have both felt like the analogy I decribed above.

 

cessna,
thanks for the description, that's exactly what I felt on Saturday, but I didn't take time to notice if it was with foot on gas or not. Why have you had 2 gxs?

 

I also have had 2 GX's and same vibration in both, plus a low speed vibration at around 30 mph, all gears.

 

Well it's a long story, but the short of it is.... Lexus bought back my first one for the Tow Hitch issue.
