Horrible Bumpy Ride

Recommended Posts

I have a 04 GX470 that bounces on every bump, dip, stone on the road, etc. It just got out of extended warranty. While it was under warranty I took it numerous times to the dealer and they said its "normal." Well now the problem has gotten alot worse. I like to drive with my head on the headrest and I just cant do it in this car because it gets thrown around too much. I had a slammed car before that drove 100 times better than this. Oh and also the steering has a shimmy too, if it could be a related problem. Any help would be appreciated or I'm gonna have to get rid of this. Thanks.

It almost sounds as if your shock absorbers are bad. Have you had them checked?

What is the position the Height Control Ride s/w. Which is placed close to your the Hand Brake lever. I have noticed this in GX, I do not know how many would agree, I have played with all the settings on the ride control s/w. If it is at the lowest, the suspension after a few minutes ride, automatically becomes very soft and cushy,( this is the softest ride . The next setting is a bit hard, but comfortable yet enough. The mid point where if selected, your ride as per the mfr is comfort, but yes you can feel this difference. The max is the Sport ride wherein the shock and Air Suspension becomes harder, wherein the compressor kicks to keep the pressure at bay with the hydraulics. This is a bit hard and you can feel it at the slightest faint road hump or bump.

You might have a leak in the air ride suspension. The rubber bump stops might be resting on the rear end housing making the ride as rough as you say. You might need a new ride height sensor or two. If this is the case, just hit the "raise" button and go for a test drive and see if it's still rough. It will automatically go to the normal position after it hit 18 mph.

I had a similar issue with my 04 over a year ago. Turned out it was the switch on the console that sets the height adjustment. It was "thinking" that the car was in something other than neutral while driving, so kept adjusting the rear as we were driving. It felt like I was riding a horse trying to throw me. The dealer replaced the switch, and that completely solved the issue. It was not cheap, and not covered by the extended warranty because the switch is defined as an expendable part. But, it was sure nice to get the smooth ride back. Hope this helps!
